Stealth technology

  1. 1. Presented by: R.ASHOK KUMAR ECE-2 25013202810
  2. 2. CONTENTS • • • • • • • • • INTRODUCTION HISTORY SIGNATURES VARIOUS STEALTHS STEALTH HELICOPTERS PROPOSED ADVANCEMENTS INDIA’s STEP TOWARDS STEALTH ADVANTAGES AND DISADVANTAGES FUTURE SCOPE
  3. 3. INTRODUCTION • Stealth technology also known as LO technology (low observable technology). • Technique which makes any object invisible to detection. • It is an important technology which used in military operations
  4. 4. HISTORY • The first "stealth" aircraft was developed in Germany during the last years of WWII. • Royal canadian army used camoufage in 1941 Americans worked on stealth technology and succeeded in 1975. • Stealth armed: China, Russia, USA, Germany, France, UK, Spain
  5. 5. SIGNATURES • Any unique indicator of the presence of certain material or troops. • TYPES OF SIGNATURES: Radio Cross Section Infrared signature Acoustic Signature Visible Signature Laser Cross Section
  6. 6. RADAR STEALTH WORKING OF RADAR
  7. 7. • RADAR stealth technique include: 1. Vehicle shape 2. Radar absorbing material (E.g. IRON BALL PAINT) • Vehicle shape
  8. 8. INFRARED STEALTH • Heat seeking missiles and other weapons zero in on the infrared glow of hot aircraft parts. • MEASURES Mixing cool air Directing hot exhausts upwards
  9. 9. VISUAL STEALTH • Unable to detect in background • Achieved using camouflages and decoys
  10. 10. SONAR STEALTH • SONAR used for detecting and locating objects submerged in water by means of the sound waves.
  11. 11. • STEALTH: Submarine is submerged at the layer of thermo cline or immediate below the layer and will not be "captured" from the wave.
  12. 12. ADAPTIVE WATER CURTAIN TECHNOLOGY • Sea water sprayed in a fashion that effectively creates an angled radar reflective curtain around the ship.
  13. 13. STEALTH HELICOPTERS • Newest addition in stealth technology. • Designs for blades have emerged that can significantly reduce noise. • Used for raid on the compound of Osama bin Laden on May 2, 2011.
  14. 14. PROPOSED ADVANCEMENTS • Hypersonics: The idea is to travel 20 times the speed of sound to avoid detection. • Employed in MACH 20 MACH 20
  15. 15. • The infrared Invisibility Cloak: Shield one’s body heat from infrared sensors, effectively making them invisible to infrared cameras.
  16. 16. • Plasma Stealth Technology: Also knows as Active Stealth Technology • Uses plasma to reduce the overall radar cross section of an aircraft. MIG 37
  17. 17. • Taranis: Autonomous and stealthy unmanned aircraft • Capable of striking targets with real precision at long range, even in another continent, is even possible
  18. 18. INDIA’s STEP TOWARDS STEALTH • HAL Light Combat helicopter: Multirole combat helicopter  Developed by Hindustan Aeronautics Limited(HAL)  3 units available • DRDO AURA: Autonomous unmanned combat air vehicle (UCAV)  developed by the DRDO  To be available in 2019.
  19. 19. ADVANTAGES • • • • Element of surprise Smaller number of stealth vehicles required Deter potential enemies from taking action Decreasing causality rates of the pilots
  20. 20. DISADVANTAGES • Cannot fly as fast as a conventional aircraft. • Reduced amount of payload carrying capacity. • Reduced flight performance • Cost  B-2 ($2 billion), F-117 ($70 million) and the F-22 ($100 million)
  21. 21. FUTURE SCOPE • Stealth technology is clearly the future of air combat. • To be incorporated not only in fighters and bombers but also in ships, helicopters, tanks and transport planes. • Not even the sky, is a limit for this technology.
