National Aerospace University "KhAI"

Our History

The KhAI was founded in 1930 as Kharkiv Aviation Institute and ever since its history has been linked to the global development of aircraft engineering and science. The first passenger airplane with retractable landing gear in Europe, called the «KhAI-1», and the first Soviet turbojet engine were designed and produced in KhAI at the beginning of the thirties. From 1937 an experienced team of KhAI researchers has been involved in the first Soviet jet rockets development. The airplanes and gliders designed by KhAI students and staff set up world records and even were produced serially and operated by USSR passenger airlines.

The rapid Institute development was interrupted by the World War II and KhAI evacuation to Kazan where the specialists’ training for aircraft industry was continued. More than 500 KhAI teachers and students went to the front, while many senior year students were employed by the Soviet defence enterprises as engineers. The Institute was moved back to Kharkiv only in 1944 after the

Ukraine is one of the few countries in the world involved in the aerospace structures and products development and manufacturing, and at the same time in highly qualified aerospace specialists training. Furthermore, the National Aerospace University “Kharkiv Aviation Institute” is the only engineering University in Ukraine that provides a full cycle of higher education in the field of aviation and aerospace science.

city was liberated by the Soviet Army. It took about 8 years to restore the completely ruined Institute buildings and facilities.

During the second half of the 20th

century the Institute’s research area was continually expanded simultaneously with regular educational process improvements. As a result, new Departments were set up and KhAI became the world leader in explosive forming, jet burners and pulse power sources development for research and industrial applications. The Students’ Design Bureau, founded in 1959, was deeply involved in design and manufacturing of new light and ultra-light airplanes, helicopters, autogyros, etc. In 1966 the KhAI was included in the list of 26 basic higher education institutions of the USSR.

In 1980s the Advance Wind Tunnels Complex and Strength Laboratory facilitated KhAI’s research in aerohydrodynamic and aircraft long-term structural strength areas. Aircraft Control Systems

and Rocket Engineering Faculties were established to meet the USSR industry’s demand for rocket engineers. The Faculty of Advanced Training was established for current aerospace industry employees.

In 1978 the KhAI was named after Nikolay Zhukovskiy and in 1980 it received the award - the Order of Lenin - for its great successes achieved in the training of highly qualified specialists and in research work realisation. Since Ukraine became an independent country in 1991, N. Ye. Zhukovskiy State Aerospace University “Kharkiv Aviation Institute” was founded on the basis of the KhAI and in 2000 the University received the status of the National Aerospace University.

Since its foundation in 1930, KhAI has trained more than 60 000 engineers. Our employees are proud of the achievements gained by our scientists in the fields of supersonic aerodynamics, aircraft structural strength, aircraft and rocket engine design, aircraft control systems, etc.

Predictive flight researches with Free-flying Dynamically Similar ModelsThe large-scale Free-flying Dynamic Model (FDM) is a re-usable unmanned research aerial vehicle capable to perform remotely-piloted or automatic pre-programmed flights with the possibility of recording in-flight information. The FDM is geometrically similar to the investigated aircraft and has the same controls. Its weight, inertia moments, autopilot coefficients and other parameters ensure that the FDM flight performance conforms to the performance of a full-scale aircraft. When necessary the pilot actions (including possible pilot errors) are simulated by the model.The major part of the FDM structure is made of composites and aluminum al-loys. The FDM onboard systems include an automatic control system, flight pa-rameters measuring and recording system and recovery system. For the FDM development we used the modular approach providing model deep modifi-cation during the flight tests.The FDM can be applied for: (i) the investigation of the most effective aerodynamic layouts with the allowance for fixed and separated external stores effect; (ii) the study of critical flight modes related to complicated 3D aircraft movement; (iii) the investigation of aeroelasticity phenomena under the energetic maneuvering; (iv) the investigation of aircraft invulnerability and reconfigurable automatic control system efficiency.

The scientists and researchers of the strength lab have developed the method of aircraft structures durability calculation. This method is based on energy fracture criterion, local stress-strain state and cyclic strain material data.In contrast to traditional methods, additional testing does not require the specific type of loading, operational conditions, flight profiles, or design solution. New material application can be studied without fatigue tests of structural elements, but on the basis of the cyclic strain material data tests only.Our method allows reducing required volume of fatigue testing and total costs for aircraft design, testing, modernization and operation.This method is applicable for:•calculation of damage equivalent for testing program or spectrum of

The Research Laboratory of Gas-tur-bine Engines and Power Plants was cre-ated within the specific R&D Laboratory of USSR Ministry of Aircraft Production. The Laboratory had conducted ex-perimental, estimative and theoretical investigations of flow parameters in the areas of steady and unsteady modes of axial compressors. Currently the Laboratory carries out the research focused on (i) the development of mathematical models of gas-turbine engines for various applications, (ii) the development of design methods for numerical investigation of impeller machines performances, as well as (iii) the improvement of compressor aerodynamic calculation methods.We are involved in collaborative proj-ects together with well-known Ukrai-nian organizations, such as Ivchen-ko-Progress State-owned Company, «Motor Sich JSC», (Zaporozhye), “TUR-BOATOM JSC” (Kharkiv), PJSC «Sumy Frunze NPO» (Sumy), Gas Turbine Re-search & Production Complex Zorya-Mashproekt” (Nikolaev).Principal Investigators•Dr.Sc.,Prof.LudmilaBoyko•Dr.Sc.,Prof.VladimirGerasymenko•Ph.D.,SeniorresearcherAlexander

The Laboratory of Gas-turbine Engines and Power Plants carries out research focused on the development of mathematical models for gas-turbine engines for various applications, taking into account the geometrical parameters of its blade rows on the mean radius and the air-gas channel shape. In the frame of this research we had developed the calculation method for the turboshaft gas-turbine engine. This method includes the description of geometric parameters of the multistage axial compressor by each row. We are developing the calculation method for the multistage axial gas turbine in a wide range of flow patterns, including the transonic regimes taking into account the cooling. This approach provides the estimation of high-temperature gas-turbine engines product performance at given geometric parameters of blade rows and air-gas channel, as well as the evaluation of its influence on the thrust, power, fuel rate, efficiency and other engine parameters. The models of definite engines developed by our team give the opportunity to take into account the influence of propellant bleeding for the spacecraft needs and channel hot section cooling on flow parameters in different engine components and its performance characteristics. Such models practical application helps to improve an engine control system during its design and final adjustment. The approaches applied to the gas-turbine engines mathematical models formation provide the usage of considerably less number of adjustment coefficients during the specific models development and their identification. This helps to decrease a human factor influence on calculation results. Within the Laboratory of Gas-turbine Engines and Power Plants we develop the methods for design and performances numerical investigation of blade machines, high-pressure trans- and supersonic axial compressor stages, fans stages, multistage axial compressors, superchargers and high-pressure centrifugal compressor stages with high engine pressure ratio. The relevant software is developed. The proposed methods are based on the 1-D, 2-D and 3-D approaches used for the description of gas-dynamic processes and blade surfaces shapes.

We have developed the advanced approach for the increasing of gas turbine engine aerodynamics efficiency. It is based on the application of main parameters and operating tolerance new robust estimation methods at the development and operation stages using the inverse problem concept.Suggested methodology is based on system aggregation, decomposition and coordination of general problem principles. It assumes general problem solving by means of distributed solution of interrelated inverse (variational, optimal control) and optimal subproblems in determinate and stochastic problem definition. If feasible solution class limits are presented, system modification problem solution synthesis is realized on the basis of regularizing algorithms. The created modification problem numerical solution evolution method is based on the genetic algorithm application.Reconstruction (modification), control and turbojet engine technical state diagnostics problems were solved with the help of developed methodology.Also the information technology allowing computer support and decision-making systems was developed:1.

The experienced researchers of the Aircraft Engine Diagnostics Laboratory de-velop multilevel mathematical complex of gas turbine engines and models of their automatic control systems. This complex provides the simulation support in control and diagnostic systems design at all stages. Initial model is a ther-modynamic model of engine units coordinated by engine design bureau. Its adequacy is provided by experimental data with the help of parametric identifi-cation method. Then the model is transformed into a non-linear dynamic model taking into account rotors dynamics, gas cavities presence and heat exchange between propellant and structural elements. To allow radial clearances change during both active and passive methods of clearances control, this model is complemented with the dynamic model of parts heat expansion, which forms clearances, and appropriate correction of units’ performances. To obtain real-time and accelerated models, this model is simplified to the quasi-linear form with the factors depending on the operation mode and ambient conditions. To form models required for ACS elements testing, the model is complemented with the execution devices and sensors, and with the propellers and other driven devices for turboshaft and turboprop engines.This model can automatically calculate the working process parameters influence on the variable parameters of units’ performances.The following models have been already developed: (i) mathematical model of engine starting mode is formed by identification methods using experimental data, and also with the help of prior data (in this case this model is interfaced with the dynamic model in operating modes); (ii) mathematical model of oil supply system operation taking into account the two-phase propellant in discharge main.Based on these models, the methods of engine control algorithms synthesis and analysis, parametric diagnostics methods, and monitoring models of boundary heat exchange conditions for different parts were developed.Also, the approach to the analysis of algorithmic detection methods of engine and its systems parameters changing was developed. Using routine flight parameters registration data and proposed method, the most efficient criteria of parameters faulty values and trend detection were substantiated.To calculate parts residuary lifetime, the method of stress-stain state monitoring models formation was developed. This method ensures formation of models with high computing power but high temperature and stresses calculation tolerance in the most heavy-loaded parts zones in real maintenance conditions. Stress and temperature are determined in real time and can be implemented in onboard systems or realized as on-ground software (fig. 3).

Its concepts are based on integrated computing of the entire life cycle of the aircraft.Design of optimal composite structuresMethods and algorithms for the design of basic structure elements (rods and bars, shells, spars and beams, flat, stiffened and sandwich panels) in consideration of strength, buckling and stiffness constraints are developed. They are based on solving of design problems of composite structures. Strength analysis of composite structuresThe following issues are developed and are currently under research:•method of prediction of strength properties of textile and 3D-woven

composites, composite physical and mechanical characteristics variation coefficients on the results of standard tests. According to this method values of an additional safety factor are determined;

•experimentalensuringsystemofstrengthcalculationofmechanicaljointsatthe best fit test condition and nature of loading in real structure;

•FEMmodelingof2Dand3Dwovencompositestrengthandelasticproperties;•methodofdefinitionofphysicalandmechanicalpropertiesofcomposites

reinforced by woven sleeves. Joints of high-loaded polymer composite parts and structuresNew structural and technological solutions of joints of high-loaded composite structural components (embedded longitudinal and transverse fastening microelements, semi-loop joints) are developed.Prediction of structural element stress-strain state under thermome-chanical loadingThe mechanism of skin panel and stiffener thermal deformation is theoretically and experimentally grounded. On this base a method of assembly stresses and strains prediction that occurs during panel installation and manufacture processes with minimum thermal and shrinkage deformation are developed; structural and technological solutions of thick skins interlaminar strength increasing to prevent delamination due to thermal and shrinkage stresses are suggested.Cost-efficient composite structures repair and curing processes Problem of energy saving during composite structure manufacture is solved by the selection of curing process optimal parameters and by using of a heating tool.

Composites Structures Design, Manufacturing and TestingThe outstanding aircraft designer, academician of the Academy of Sciences of Ukraine Oleg Antonov led the creation and development of the Laboratory of Composite Materials. The Laboratory was established in 1971, after the successful static testing of the An-2M fuselage, which was the first large-scale aircraft unit made of polymeric composite materials in the Soviet Union.

Currently, the actual problems of design and manufacture of polymeric composites for aviation, rocket and space structures are under the research of our Laboratory.

Software development for automation of spacecraft testing systems Testing of spacecraft systems is a part of experimental improvement, and includes test object control tools at production level, preparation to work etc. The software for tests automation should work under real-time constraints, be reliable and resilient to hardware failures, be adapted to various tests purposes and problems, various configurations of control test and measuring equipment, and it should clearly and completely meet customer requirements (system developer) in control algorithms.

During test automation software development the following methods were theoretically grounded and tested in real life projects:

•Data processing method maintaining reliability and urgency of results control. It is based on the model of measured or calculated value, taking into account the history of measurements, their errors and obtained time intervals.

•Language-oriented approach, which involves algorithms of control and tests specifying in terms and in the anguage of the customer.

This approach allows us to eliminate software modification during testing, and to ensure flexibility and efficiency of modification of test scenarios technologi-cal processes.

The development of spacecraft systems test automation software was performed in such projects as «Microsputnik», «EgyptSat-1», «MC-2-8» within the framework of First National Space Programme of Ukraine (1993 -1997), Second and Third National Space Programmes (1998 - 2002 and 2003 - 2007), and State purpose science and technology space programme of Ukraine (2008 – 2012).

In 1977 the KhAI’s Department of Engines and Power Plants started R&D work in the area of ion-plasma technologies. The new area introduction was based on the wide experience in the development, investigation and improvement of electroject thrusters and other plasma sources and accelerators. Extensive knowledge in the field of plasma fluxes generation/acceleration and their interaction with the structure elements of plasma devices and with the environment gave the opportunity to create the unique processing plant “Vikhr”, based on the arc plasma sources and protected by a set of inventor’s certificates. A new type of the process plasma source, belonging to the magnetron systems class, so-called “quasimagnetron” plasma source, was developed. Several plants based on this source were created. In 1995 by the joint decision of the National Space Agency and the Ministry of education of Ukraine, the Interbranch S&T Center of Space Power and Propulsion was established. The Team of Ion-plasma Technologies and Equipment is part of this Center.

grinding technology ensuring the highest productivity of definite metals and alloys grinding (heat resistant and high-temperature nickel-chromium alloys, titanium alloys, chilled cast iron, magnetic alloys etc.), excluding grinding burns formation and providing part lifetime increasing.

2. Manufacturing, testing and optimization of specialized equipment and technique.

3. Methods and equipment for design and experiments in planetary grinding for wide range of materials.

Technology SpecificationThe offered technology is unique and doesn’t have similar analogues.This technology is implemented on usual grinders with the planetary-grinding head installed on a spindle. Thus usual grinding wheels and cutting emulsion are used. Provision of the fullest proceeding of adsorption-plasticizer effect in the contact zone results in the sharp decrease of cutting forces and contact temperatures in the cutting zone. It excludes burns formation and provides formation of compression residual stresses in workpiece surface layer resulting in substantial increase of the part lifetime.Basic characteristics:1.

with usual technology of deep grinding.4. It allows decreasing consumption of cutting emulsion in 5-9 times.5. It allows decreasing heat-intensity of process in 7-10 times and to exclude the

Nanotechnologies application for aerospace components improvementWe develop the theoretical foundations of nanotechnologies based on the application of ion flows, electron flows, plasma flows, laser emission and their combination. They are used for knowledge-based selection of flow characteristics that will ensure the required nanostructure development. Also, we estimate analytically the nanocoatings adhesion to the most used structural materials. All developed theories have been validated by theoretical and experimental data comparing.

Currently, we assess the applicability of multi-process treatment for nanocoatings deposition on aerospace and medical components and design an improved unit for multi-process treatment and multilayer nanocoatings deposition for components life-time increasing. Due to the advanced mathematical simulation of the used technological processes it is possible to receive pre-defined nanostructures and achieve the required operation characteristics.

Coating and surface hardening of aerospace componentsWe have developed a theory of plasma-ion technology, ion-implantation dop-ing and laser treatment as well as multi-process treatment technology based on their combination. Also, we have developed a methodology for cutting tools selection taking into account stresses generated in the coating during the machining. Today we study these technologies application in aerospace industry. Our researches are focused on 1) aerospace components service life increasing; 2) increasing of cutting tools durability for heat-resistant steels/alloys and hardened steels aerospace structures machining; 3) laser treatment ap-plication for small size holes broaching and grooves slotting; 4) laser treatment of superhard ceramic components and artificial diamonds with up to 6.6 mm3/min machining rate.

Also we design lab-scale and industrial units for stable thickness coatings de-position and surface multi-process treatment. We expect that combination of plasma-ion, ion-beam and laser surface treatment techniques with electric-discharge hardening and electron-beam treatment will significantly increase hardening layer thickness and cutting tool wear resistance and durability.

Advanced Hardening and Machining Technologies

The Research Centre of Innovative Technologies in Mechanical Engineer-ing was established in 1980. Since than more than 1000 research papers, 7 patents and 20 inventor’s certificates have been issued. Also, 21 Internation-al Conferences on “New Technologies in Mechanical Engineering” were held in 1992 - 2011.As a result of the Centre’s long-term research, multi-process technology for surface hardening based on plasma-ion, ion-beam and laser surface treatment techniques was developed. Appropriate industrial multipurpose convertible vacuum unit for coatings deposition and surface hardening was designed based on the similar lab-scale unit development and testing. Also, high efficient laser facilities for 3D superhard ceramic parts machining, holes broaching and small size grooves slotting (0.1-0.3 mm) were developed.The Centre is equipped with lab-scale units for ion-plasma coatings deposi-tion and surface multi-process harden-ing, Carl Zeiss Jena atomic adsorption spektograf, LV04 Magnifier time with nanosecond resolution and large vari-ety of instruments for surface harden-ing and coatings quality assessment.Principal Investigators•Dr.Sc.,Prof.GennadiyKostyuk•Dr.Sc.,Prof.ValeriyFadeev•Ph.D.,Ass.Prof.VitaliyPavlenko•Ph.D.,Ass.Prof.UriySysoev•Ph.D.,Ass.Prof.UriyShirokiy

The main activities of the KhAI Research Group of Electrohydraulic Forming (EHF) include the development of modern technologies and equipment for forming of sheet parts with a complex geometry.

The sequential local loading of blanks, generated pressure fields, pressure distribution, deformation and temperature influence on the forming processes are thoroughly studied.

EHF Research Group have developed the high-quality electrohydraulic presses with controlled heredity, which is especially important for aerospace and other transport parts manufacturing.

Manufacturing facilities for EHF available at KhAI include:

•electrohydraulic press for small-size components manufacturing allowing to manufacture sheet parts with maximal dimension of 300 mm •multi-circuit electrohydraulic press for large-size sheet parts production.

Principal Investigators•Ph.D., Ass. Prof. Mykhaylo Knyazyev •Dr.Sc., Prof. Mykhaylo Taranenko

The great advantages of electrohydraulic presses application for sheet parts industrial manufacturing over the sheet-metal presses are high technical ca-pabilities and sufficiently low time and cost expenses for production planning. In comparison with the traditional technology, the electrohydraulic sheet-metal forming is characterized by the great simplification of tooling, reduction of ma-terial consumption for dies (from 5 to 15 times) and initial sheet blank (by 10 to 30 %), large shortening of pre-production periods, reduction of energy and cutting-tool material consumption for forming tools manufacture, large short-ening of pre-production periods and great reduction of waste during these periods, as well as significant increase of cost efficiency under conditions of small and middle scale production. KhAI EHF Group is extensively involved in the following research activities:•Electrohydraulic forming processes research.•Development of technologies for EHF presses available power increasing

and four-dimensional guidance for applied loads.•Study of pressure fields generated by discharge chambers of various geo-

metric shapes with single electrode pair (wire-initiated and wireless).•Research of uniformity of pressure fields distribution and repeatability from

one discharge to another for reliable EHF industrial application for sheet components of small sizes (up to 300 mm).

•Testing of discharge chambers made of non-conductive materials.•Study pressure fields generated by multi-electrode discharge blocks includ-

ing non-linear effects of interaction of several shock waves for sheet compo-nents of large sizes (up to 1600 mm).

Works on the smart EHF press development were carried out. As a result the automated control system for EHF press was designed. This system provides measurement of actual geometric shape of a sheet blank during forming process and automated correction of pressure loading field for the next discharge with voltage (energy) correction and optimized electrodes connection.Among other research activities in this field is the investigation of EHF process combined with differential sheet blank heating. This process is applicable for forming of parts made of high-strength low-plasticity titanium alloys. Also, the influence of high-rate deformation on microstructure and mechanical properties of carbon and alloyed steels, aluminum and titanium alloys, is under the survey of KhAI EHF research group.

The complete “Top Torch” equipment for the extraction of granite blocks is offered. Thermo-gas-stream cutter is the main and unique element of our equipment and has the equivalent thermal power of 400 kW. It has an external diameter of 75 mm and optimized angle of the cutting jet. This allows significant reduction of the production costs in mining blocks (cutting speed is up to 2 m2 per hour and the cost of diesel fuel for cutter operation does not exceed 33 litres per hour). The cutter fuel system provides fuel supply to the cutter in a wide temperature range from -40oC to +40oC. The cutter has a standby mode that reduces the fuel consumption and unproductive time. Figure 1 shows the application of our cutter on the granite quarry in Ukraine. We also have developed the complete “Piromaster Plus” equipment for high-performance cleaning. We were the first who created cleaning equipment based on rocket engine. We used our experience of aerospace equipment development for its conversion to civilian industry. Our equipment is reliable and easy to operate. Unlike existing analogues our equipment has a high performance and it is also multifunctional. It provides the cleaning of buildings, bridges, pipelines during their repair or construction. Figures 2 and 3 show the gas pipeline purification for corrosion protection developed for Japanese colleagues. Its cleaning capacity is up to 60 m2 per hour and its fuel consumption is from 9 to 12 litres per hour. For customer requirements we have completed the equipment with an effective dust control system. Currently, the Laboratory is conducting research supported from the state bud-get and by private investments and has initiated the following programmes:•studyofcompoundliquidrocketfuelcomponent,basedonammonia,and

the possibility of establishing low-power supply systems;•creationofhigh-speedcombustionchamberofair-jetenginewithdeepfuel

pathogenic waste by phasing the impact of supersonic jets with a high temperature”;

•implementationoftheproject“Watervapour-gas-emulsiongunwithahighvolumetric productivity of flame retardant substances for remote fire fighting in especially difficult circumstances”.

The Electron Microscopy Laboratory was founded in 1972. In 2008 it was re-equipped with modern facilities, such as scanning electron microscope SEM-106 with X-ray energy-dispersive analyzer and SELMI TEM-100-01 transmission electron microscope. The Laboratory’s equipment allows performing of electron-microscopy and optical investigations of objects with different nature.Currently, we are working in the following areas: surface structure investigation, investigation of ultimate composition in local objects’ areas, high-precision analysis of chemical elements distribution, chemical mapping, high-resolution images (e.g. of microelectronic devices, polymers, conductors, massive and thin-film dielectrics etc.) obtaining in high and low vacuum, metals and coatings investigation.

Research on semiconducting solid solutions self-assembling depends on growth conditionsSemiconducting solid solutions of CdZnTe type are widely used in electromagnetic radiation monitoring. We conduct research focused on the establishment of principles of self-assembling of such materials’ structure and the process dependence on the growth conditions and impurities. This research helps to analyze how the material structure affects crystals electric properties. Also, the study of CdZnTe-type crystals defects, the structures characteristics and electric and photoelectric properties leads to the development of new methods for the research on CdZnTe-type crystals properties.

Electroject engines lifetime analysisAs currently available lifetime tests of electrojet engines require significant time and financial resources, we propose to use electron microscopy capabilities, which help to overcome such problems. The study of sputtered surface microstructure gives an insight into the nature of engine structures and plasma steam interaction and helps to predict an engine’s lifetime. The information on the elements’ composition and surface structure enables an optimal selection of materials (e.g. to select the most spray resistant one), and investigation of how the changes of initial engine design affect an engine’s lifetime.

Cathode emission material researchScanning Electron Microscope (SEM) is applied for analysis of emission materials used in hollow cathodes-compensators. By the use of electron microscope we can control the quality and uniformity of emission samples stoichiometric composition at each stage of emitter production: batch manufacturing, samples molding, annealing. Also, electron microscopy can provide the information on surface migration and changing of active components number in the emitter. In particular, the study of low porous emitters’ surface by electron microscopes provides the important information on samples porosity, topography and grain sizes.

Radio engineering systems synthesis and optimizationWe apply the systems approach for radio engineering systems design and optimisation, which involves synthesis of active/passive system structure and development of algorithms for signal parameters estimation and processing that is based on particular set of quality criteria. This approach can be applied in different areas of radio physics, such as remote sensing, radio astronomy, diagnostics, etc.In cooperation with several international partners our researches are involved in the development of technologies for geophysical Antarctica study within the «Instruments for remote sensing of subsurface Antarctica layers» programme. Also, in collaboration with the National Academy of Sciences of Ukraine we are working on “Methods and instruments of effective resolution of signals with unknown form in radio engineering systems”, “Optimization of spatio-temporal fields processing in radiometric systems” and other subject research projects.Theoretical performance limit on mono/multi/hyperspectal images pro-cessingIn collaboration with the Institut d’Electronique et de Télécommunications de Rennes (IETR) and the University of Rennes 1 (France) we are developing the unifying approach allowing to set a theoretical performance limit on fundamental image processing tasks. The overall aim is to model image content by fractal Brownian motion model. We are able to parameterize a given image and formulate different image processing tasks within statistical maximum likelihood approach. Theoretical performance limit is obtained as a corresponding Cramér–Rao lower bound (CRLB).Three image processing tasks were considered: image filtering, blind noise param-eters estimation, and image registration with subpixel accuracy. CRLB on image filtering was obtained for local component-wise or vector filters under additive and spatially uncorrelated noise hypothesis. It was experimentally shown that our bound allows predicting the state-of-the-art filters accuracy with an error less than 30%. CRLB on image noise parameters estimation accuracy was derived for various noise and image combinations: additive, Poisson-like, multiplicative noise, mixtures of additive and Poisson/multiplicative noise or general polynomial dependence of noise variance on image intensity; both spatially uncorrelated and correlated noise; mono/multi/hyperspectral images. A wide spectrum of possible situations is a unique feature of our approach. For subpixel image registration, the proposed CRLB bound on pure translation estimation accuracy describes more adequately the performance of conventional estimators than other existing bounds. This holds with respect to the images SNR value, the images texture roughness, their correlation and the actual value of translation parameters between their grids.

Multichannel data (signals, images) processing requires a high degree of automation as the amount of data is extremely large and should be processed and delivered to users with proper quality and speed. So the quality of original (registered, acquired) and processed (filtered and/or lossy compressed) data is of great importance. To characterize this quality, one needs methods and algorithms for blind determination of noise and other distortion (e.g., blur) type and characteristics. Recently to solve this task our research team in cooperation with the University of Rennes I (France) developed several approaches, including blind estimation of mixed noise component variances (see Fig. 1) using scatter-plots and robust curve fitting. Also, we have designed the method of noise spectrum blind estimation. Besides, adequate visual quality metrics (indices), both full-reference and non-reference are required. Several full-reference metrics including PSNR-HVS-M and PSNR-HMA have been proposed and analysed. Their verification has been carried out for the largest in the World database TID2008 created in cooperation with the Tampere University of Technology (Finland) and the University of Rome III (Italy).The procedures for automatic setting of the parameters of lossy compression methods to provide either visually lossless compression or noisy image coding in the neighbourhood of optimal operation point have been designed. Proposed lossy compression techniques provide compression ratio about 1.5 larger than JPEG or JPEG2000 for the same visual quality due to partition scheme optimization (see Fig. 2), use of special quantization tables for DCT coefficients and their efficient coding. Being modified and applied to hyperspectral data compression and taking into account sub-band image cross-correlation and spectral abundance, the lossy compression methods provide the compression ratio up to 20…50 without decreasing the probability of correct classification of multichannel remote sensing data. Additional increase in classification accuracy can be provided if an image filtering is carried out on-board or on-land in automatic or semi-automatic mode (Fig. 3). The proposed estimation, compression, filtering and classification techniques and software have been tested for AVIRIS, HYPERION, LandsatTM, TerraSAR and other multichannel remote sensing data as well as for other types of signals and images including micro-Doppler radar data and higher order time-frequency representations (in cooperation with University of Montenegro), multichannel ECG, color images from mobile phone digital cameras, etc.

Cross-functional environment for intelligent tutoring programmes creation

One of the methods to increase traditional training process efficiency is to use intelligent computer tutoring programmes (ICTP). ICTPs utilize effective pedagogical principles and practically unlimited memory sizes and thus they are capable to provide a detailed estimation of trainee competence current level and to form individual approach to trainees by the received competence estimation. The main disadvantage of ICTP is its low time efficiency and high intellectual expenses when it comes to programme realization and further work support. To overcome these difficulties it is proposed to use special author’s tools of ICTP development allowing creation of training computer support with small enough time expenses and without any programming skills.The cross-functional environment is intended for the automated computer tutoring programmes creation without any programming means. The environment consists of two programmes:1. ICTP editor. ICTP construction process is the following:•ICTPcompetencecomponents(CC)baseformation(knowledgeandskills

elements which trainees have to acquire as a result of ICTP execution).•CTPtasksinterfacedesignusingapaletteof16visualelementstypes.•CCmodels for each task creation and tasks properties editing (name,

evaluation mode, help information).•ICTPassemblagecorrectnesscheckandICTPsaving.

2. The application which translates editor-created ICTP and organizes collaborative application-trainee work. Next ICTP task selection is performed due to the operation of developed decision-making methods which analyze CC structure for each task and trainee mastering degree.

The main features of the cross-functional environment are the following:•Automatedrapidcreationofcomputertutoringprogrammeswithoutuseof

any programming tools;•Easy-to-useinterface;•Differenttypesofcreatedprogrammes(lectures,labsandpracticals,tests,

demonstration tools);•Tools forcollectionandanalysisof tutoringprogrammeexecutionstatistics

data.A number of computer tutoring programmes on technical and humanitarian disciplines have been developed on the base of cross-functional environment. Results of created ICTPs work analysis confirm their high degree of efficiency in comparison with the results of traditional training form.

Personal health monitoring system ETH-KhAI IMONThe complexity of modern medical systems continually grows to meet ever-increasing demands in functionality and performance. XAI-Medica in cooperation with ETH Zürich (Switzerland) work on the development of advanced Telemedicine Intelligent Health Monitoring System for real time remote vital signals monitoring. It will monitor and process patient’s 12-channel ECG, respiration, cardiac output, circulation and motion activity. Based on the wireless technology ETH-KhAI IMON System will support self diagnostic, self care and cardiac rehabilitation programmes in the home environment using mobile phones and PDA’s. The system will enable the patient to spend much more time at home during examination, treatment and rehabilitation periods.Continuous Blood Pressure MonitoringBlood pressure measurement is the most frequent medical examination worldwide. Current non-invasive measurement devices are based on oscillometric and auscultation methods. They are simple and reliable, but application of inflatable cuff makes them inconvenient for the patient and unsuitable for continuous monitoring. We have developed a reliable method for blood pressure continuous measurement without squeezing cuff application. It is based on simultaneous measurement of several cardiovascular parameters, like blood flow, heart rate, HRV and pulse wave velocity. Measured bio-signals are recorded, processed and used for calculation of systolic and diastolic blood pressure for each pulse. Our Continuous Blood Pressure Monitor can be easily applied for blood pressure monitoring in a home care environment. Fetal ECG monitoringFetal Electrocardiogram (ECG) monitoring during the women pregnancy period has a great clinical importance. Reliable reading of the fetal ECG provides an opportunity for physician to detect problems in the fetal heart activity even before the child is born. XAI-Medica have developed wireless Fetal ECG Monitor and associated software for non-invasive monitoring of heart rhythms and ECGs of both fetus and mother during pregnancy which has strong advantages over the currently used Doppler units. Our technology is based on the Blind Source Filtering and Separation technique that allows recovering of very low fetus ECG signal from the background noise and high amplitude maternal ECG. As a result, long term fetal and maternal heart rate traces can be received for mother and fetus HRV parameters evaluation. The system also allows the recovering of complete PQRST complex of fetal ECG for waveform analysis of the fetal ECG. Developed Fetal ECG Monitor can be used for long term fetal rhythm/ECG monitoring in home environment (Fetal Holter).

University Experience in International Collaborative ResearchNovel Railway Haulage Aerodynamics

The project was implemented in the frame of research contract with Curtin University of Technology, Australia. The main tasks of the project were to determine the influence of the rail haulage train shape onto its aerodynamic properties and to select wagon design configurations with most potential for reducing air drag.In the frame of the project, the KhAI researchers have generated the recommendations on the optimal methods for aerodynamic drag reduction of long open-wagon haulage train. The preliminary computational modelling was conducted to determine the dimensions of the design area, turbulence models and boundary conditions. Then the 3-D models of various aerodynamic regimes of locomotive and open-top rail wagons and their modifications were developed.The air resistance coefficients for different values of oncoming flow speed were determined by two methods: 1) numerical modelling of flow about the rolling-stock and 2) physical modelling - 1:40-scaled train model wind tunnel testing in a range of cross-wind angles. As a result, the optimal configuration of the long open-wagon haulage train in terms of air drag reduction was determined. The outputs of this project are of the significant importance for Australian Railway and are supposed to be applied in railway industry.

• language-oriented approach, which includes control and verification algorithms specifying in terms and in language of customer, and following automatic execution of these specifications.

Research on the development of special-purpose software for spacecraft systems tests automation was performed within «Microsatellite», «EgyptSat-1»and «MC-2-8» projects in the frame of the National Space Programmes of Ukraine (1993-2007) and are in progress today under the State Target Science and Technology Space Programme of Ukraine for 2008-2012.The figure below represents the developed software package for automation of spacecraft systems testing.

Space Vehicles Advanced Thermal Control Systems based on the Two-Phase Mechanically Pumped Loops

The project is currently implemented in the frame of bilateral collaboration of KhAI and THALES ALENIA SPACE Corporation. It is aimed at the development of innovative space vehicle’s thermal control system on the basis of two-phase mechanically pumped loop approach. The proposed thermal control system will have strong advantages in power consumption, thermal control precision, thermal resistance, and heat transfer distance in comparison with existing thermal control systems. Above-mentioned advantages will be particularly significant for high power space vehicles (e.g. next generation of communication satellites). Within this project KhAI scientists are responsible for the development of thermal control system and its key elements for perspective telecommunication satellite of THALES ALENIA SPACE Corporation. The unique experimental prototype of thermal control system based on two-phase mechanically pumped loop have been already created and tested. System operability and efficiency have been confirmed by excellent correspondence of numerical calculations and experimental results in normal and microgravity conditions. The project is planned to be completed by September, 2013.
