2. Date Stealth Technology  Scientifically know as LOW OBSERVATORY.  Used in military aviation  Reduces detection range of an air craft  Similar to camouflage tactics used by soldiers  Partial indivisibility to radar and other detection

3. Technical SeminarDate  The first “STEALTH” aircraft have been developed in Germany during the last years of WWII.  This technique has also been used in ships.  Later Americans worked on stealth technology and succeeded.

4. Technical SeminarDate  Electromagnetic radiation with longer wavelengths than those of visible light.  frequency range approximately 430 THz down to 300 GHz.  thermal radiation emitted by objects near room temperature is detected. Infrared radiation

5. Technical SeminarDate  In this stealth the aircraft injects a stream of ionized gas

7. Technical SeminarDate What Is RADAR ?

8. Technical SeminarDate Almost since the invention of radar, various techniques have been tried to minimize detection Some of the techniques used for this purpose are:  1.Vehicle shape  2.Radar absorbing material

9. Technical SeminarDate  Rad ar absorbing materials  Acute angle  Design of NOSE  Stealth air craft must bury the engines within the wings

10. Technical SeminarDate A corner reflector is a retro reflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects electromagnetic waves back towards the source

11. Technical SeminarDate Stealth technology is used Using Normal shape

12. Technical SeminarDate Normal fighter plane showing the engine Engines of the aircraft are covered

13. Technical SeminarDate Exhaust PLUME of a normal plane Stealth Aircraft without Exhaust

14. Technical SeminarDate Nanostructural composite material, absorbing without reflection radar wave.  Magnetic ferrite-based substance  RAM reduces the radar cross selection making the object appear smaller.

21. Technical SeminarDate Future Of The S TEALTH

22. Technical SeminarDate  Stealth technology developed a lot.  Investment needed is very high.  High chance of low cost gain.  A lot learned about signature reduction and absorption.  Success yet to be proved extensively.  Useful for other projects.
