Transcript

  • 1. DRK College of Engineering & Technology Date Technical Seminar
  • 2. DRK College of Engineering & Technology Technical SeminarDate 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. DRK College of Engineering & Technology 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. DRK College of Engineering & Technology 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. DRK College of Engineering & Technology Technical SeminarDate In this stealth the aircraft injects a stream of ionized gas
  • 6. DRK College of Engineering & Technology Technical SeminarDate
  • 7. DRK College of Engineering & Technology Technical SeminarDate What Is RADAR ?
  • 8. DRK College of Engineering & Technology 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. DRK College of Engineering & Technology Technical SeminarDate Radar absorbing materials Acute angle Design of NOSE Stealth air craft must bury the engines within the wings
  • 10. DRK College of Engineering & Technology 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. DRK College of Engineering & Technology Technical SeminarDate
  • 12. DRK College of Engineering & Technology Technical SeminarDate Normal fighter plane showing the engine Engines of the aircraft are covered
  • 13. DRK College of Engineering & Technology Technical SeminarDate Exhaust PLUME of a normal plane Stealth Aircraft without Exhaust
  • 14. DRK College of Engineering & Technology 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.
  • 15. DRK College of Engineering & Technology Technical SeminarDate
  • 16. DRK College of Engineering & Technology Technical SeminarDate
  • 17. DRK College of Engineering & Technology Technical SeminarDate Crew one Length 19.4m(63ft 9in) Height 3.9m(12ft 9in) Weight 23625kg Angle of Sweep of Delta Wing 67`
  • 18. DRK College of Engineering & Technology Technical SeminarDate
  • 19. DRK College of Engineering & Technology Technical SeminarDate Reduces the causality rates during war Saving military budget. Develop the military secretes Bluff the anti-detective device Stealth aircraft are invisible to radar
  • 20. DRK College of Engineering & Technology Technical SeminarDate .
  • 21. DRK College of Engineering & Technology Technical SeminarDate Future Of The STEALTH
  • 22. DRK College of Engineering & Technology 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.
