1964 by merger of all three companies

Evolution and Expansion

• 19 Production Units and 9 Research and Design Centers

• 12 types of aircraft manufactured with in-house R & D

and 14 types produced under license.

• manufactured over 3550 aircraft, 3600 engines and

overhauled over 8150 aircraft and 27300 engines.

GYROSCOPE

• Any heavy rotating mass can be called gyro .

• A gyroscope is a device for measuring or maintaining orientation, based

on the principles of conservation of angular momentum

BASIC PROPERTIES OF GYRO

• Rigidity:• The axis of rotation (spin axis) of the gyro wheel tends to remain in a fixed

direction in space if no force is applied to it.

• Precession:• The axis of rotation has a tendency to turn at a right angle to the direction

of an applied force.

TYPES OF GYRO

There are three types of gyro:• Mechanical rate gyro

• Piezoelectric gyro

• Micro electric mechanical system gyro

MECHNICAL RATE GYRO• The mechanical rate gyro uses an electric motor to spin a small disc or

flywheel . • When the gyro was moved about the axis the spinning disc tilts and this

tilt is picked up electronically by a potentiometer.

PIZOELECTRIC GYRO

• piezoelectric gyro which uses a quickly vibrating crystal. As the crystal

vibrates, an applied rotational force will cause disturbances in it’s wobble

which create a small, but measurable electric current proportional to the

rate at which the gyro is rotated.

• Advantage:

• More sensitive than mechanical gyro.

• Disadvantage:

• they’re very temperature sensitive and going from hot to cold or vice versa

will cause them to act erratically.

Micro Electric-Mechanical System gyro

• MEMS are molecule sized machines that are fabricated on top of a piece of

silicon, along with the electronics to interface to them.

• They vibrate at a high rate .

• As the gyro rotates, there is displacement of the mass and the signal is

generated by the gyro .

TYPE OF FUNCTIONING OF GYROS

• There are two type of gyro functions

• Rate Gyros:

• They only sense the turn rate or the angular acceleration of the

aircraft.

• Heading hold gyros:

• They keeps tracks of all turns and provide the final orientation

from the set position.

BLACK BOX

• Two main parts of the Black Box are:

• Flight data recorder:• It is a device used to record specific aircraft performance

parameters

• Cockpit voice Recorder:

• It records conversation in the cockpit, radio communications

between the cockpit crew and others.

USE OF FDR

• The data recorded by the FDR is used for accident investigation.

• Analyzing air safety issues.

• Analyzing material degradation and engine performance.

FUEL CONTENT GUAGE

• Consist of two parts: Sensing unit: it uses a float connected with the potentiometer.

Indicator indicate the level of fuel.
