Objectives of this workshop

In a Bachelor Engineering course students are mainly involved in theoretical aspects of aircraft design and it’s elements. But realization of an real aircraft involves various phases . As a student it would be ambitious to realize the full size aircraft of any aviation category. Hence it would be more appropriate to design an aircraft which is of a realizable size. UAVs of smaller size would perfectly suit this need. Hence the work shop deals with the design, fabrication and field testing of an small sized UAV.

How this is useful for the students?

• Realization of an aircraft involves all the aspects of Aeronautical Engineering. The students will have a chance to match their theoretical knowledge to the practical aspects of designing and realizing the product which is of critical importance

• In a real industry environment , it is required to work on the design and analysis of real aircrafts. Once they are clear with the whole process of design they would able to understand and perform better in their organizations.

Who will be the Trainers & Instructors??

• Young & Dynamic Aerospace Engineers working in the Industry from several years on variety of aircraft design projects

• Design Engineers who in the past have worked on the India’s ambitious aircraft design projects (MAVs, UAVs, SARAS, NM5 etc..) at various organizations like IITs, NAL, ADA etc..

• In the present working as Consultants, Project leaders for various AIRBUS design projects & with major European Suppliers for aircraft manufacturing companies worldwide

• Having an experience in the aerospace industry of over 5-7 yrs

• Manufacturing and hangar training will be provided by experienced Aircraft Maintenance Engineers (over 10-15 yrs of experience)

E// Aircraft Requirements

• Areas to be met to build a successful fl platform

– Aerodynamics

– Propulsion

– Structure

– Stability, performance and Controls

– Cost aspects

F// Design Methodology

1. Ground up approach – Learn all the basics, then design your vehicle

around your mission requirements • Aerodynamics Propulsion Structure

Performance Stability and Control etc.

2. Empirical approach – Use essential data from previously designed

aircraft in particular category to determine the baseline, then worry about the details

– Weight wing size engine size etc.

F// Design Methodology

• Empirical design method (One of the many ways) – Estimate weight (TOW or Wo) based on known payload – Estimate wing size based on known speed and lift

coefficient – Select wing shape and aspect ratio based on type of

aircraft – Select C.G. location based on static margin requirements

(Stability) as given distance from a.c – Select wing twist, if any – Size control surfaces based upon tail distance from C.G – Iterate

• Need baseline data

UAVs vs Convn. AC

• What makes UAV design different from traditional aircraft design

• They both are designed around payloads, but. . .

The problem

• Low speed, small size

• High Altitude

– Low density

• UAVs Re = 10^5 – 10^6

• MAVs Re = 10^4 – 10^5

• Viscous forces are significant- separation prevalent : low L high D low L/D

• Outside of “Classical Aerodynamic Design”
