2. STEALTH TECHNOLOGY Presented By SUPREETH.S (4MH07ME047) Mysore, karnataka

6. RADAR CROSS-SECTION REDUCTIONS 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

8. A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects electromagnetic waves back towards the source.

10. CASE STUDY ON NIGHTHAWK PLANES

11. Nighthawk design Crew One Length 19.4m (63ft 9in) Height 3.9m (12ft 9in) Weight 23,625kg (52,500lb) Angle of Sweep of Delta Wing 67°

12. A: Two imaging infrared turrets are recessed into the nose of the F-1 17. One looks forward to acquire targets; the other is on the underside and is used for tracking and laser designators . B: The edges of the F-1 17's cockpit canopy, like all surfaces on the aircraft , have no right-angles-these are strong reflectors of radar. C: The unique arrow shape of the F-117 is naturally unstable. Stability is maintained by computerized fly-by-wire controls. D: Bombs are strong radar reflectors, so the F-1 17 carries its weapons internally. The bomb doors only open for a moment when the warload is released. E: The Nighthawk's twin General Electric engines are buried deep in the fuselage. They have shallow exhausts, which cool and deflect the exhaust gases upward to minimize heat emissions. F: it is kept at an angle in order to reduce the detected by the radar.

13. ENGINES OF THE AIRCRAFT ARE COVERED NORMAL FIGHTER PLANE SHOWING THE ENGINE

14. STEALTH AIRCRAFT WITHOUT EXHAUST EXHAUST PLUME OF A NORMAL PLANE

15. Sensors

17. COCKPIT

19. FLIGHT MANAGEMENT

23. B-2 STEALTH BOMBER

24. In this stealth the aircraft injects a stream of ionized gas which envelopes the aircraft due to which most of the radar wave are observe this make the aircraft completely invisible PLASMA STEALTH

27. CONCLUSION  Stealth technology is a techniques used with Aircrafts, ships order to make them less visible to radar.  Need of Stealth Technology very importance in military field.
