single seat fighter is smaller, lighter and costs less than an equivalent two seat version. improved aircraft performance, control and better handling. reduction in maintenance costs. secure communication. 7dr gemson, IIAEM, JU, Bangalore
Avionics in Space systems: Fly-by-wire control system used for space vehicle’s attitude and translation control. Sensors used in the spacecraft for obtaining data. Autopilot redundancy system. On-board computers used in satellites for processing the data. Automatic checkout Communication with outside world8dr gemson, IIAEM, JU, Bangalore
dr gemson, IIAEM, JU, Bangalore9Unmanned Aerial Vehicles (UAVs) : It should be noted that unmanned aerial vehicles are totally dependant on the avionic systems.
10Typical Core avionic systemsdr gemson, IIAEM, JU, Bangalore
The application of avionics covers a very wide area each part fulfilling a specialized function.Avionics system of an aircraft comprises of (i) Navigation, (ii) Communication, (iii) Flight control consisting of stability augmentation and autopilot, (iv) Engine control, (v) Flight management, (vi) Subsystem monitoring and control, dr gemson, IIAEM, JU, Bangalore11
(vii) Collision avoidance, (viii) Weather detection (ix) Emergency locator transmitter (ELT), (x) Radar, infrared, and other target sensors, (xi) Weapon management system, (xii) Electronic countermeasures, (xiii) Mission planning, (xiv) Formation flight. Subsystems listed from (i) to (ix) are common to both civil air lines and military aviation Subsystems listed under (x) to (xiv) are for military aircraft.dr gemson, IIAEM, JU, Bangalore12
dr gemson, IIAEM, JU, Bangalore13Avionic System requirements:Minimum weight.Compatible to operate adverse operating environment particularly in military aircraft in terms of operating temperature range, acceleration, shock, vibration, humidity range and electro-magnetic interference.Possessing very high reliability, safety and integrity.Minimum volume particularly in military aircraft requiring an emphasis on miniaturisation and high packaging densities.
Unit 1Aerospace Avionics – Navigation and Navigational Aids:Introduction to basic navigation; Maps and Geodesy: WGS – 85 system; Coordinate system and transformation; great circle and rhumb line navigation; dead reckoning.Objectives: At the end of this session the student should be familiar with basic concepts of navigation and the need for the same with special reference to aerospace vehicles; general categories, methods and terminologies associated with navigation. dr gemson, IIAEM, JU, Bangalore14
dr gemson, IIAEM, JU, Bangalore15One of the avionics subsystems is navigation system which will be addressed in the following sections. Following aspects will be covered.What is navigation in general and as applied to aeronautical vehicles?
