  1. SEMINAR ON “APACHEHELICOPTERS” SUBMITTED BY:- NAME:- SHANKHADEEP BHATTACHARYA REGD. NO.:- 0901223305 ROLL NO.:- 09ME050 DEPART MENT OF MECHANICAL ENGINEERING KRUPAJAL ENGINEERING COLLEGE PUBASASAN KAUSALYAGANGA BHUBANESWAR

  2. HISTORY • Developed by Hughes Helicopters in 1970s. • Took its first flight in 1984. • Primary Users:- United States ArmyIsrael Air ForceEgyptian Air ForceRoyal Netherlands Air Force • Unit Cost:- US$20 million .

  3. Apache Versions

  4. APACHE—A Flying Tank • Four-blade, Twin-engine attack helicopter • Tail wheel-type landing gear arrangement • Tandem cockpit for a two-man crew • Nose-mounted sensor suite for target acquisition and night vision systems

  5. PARTS

  6. ROTORS & BLADES • An Apache has double tail rotors, each with two blades. • Spins four 20-foot (6-meter) blades • The core structure of each blade consists of five stainless steel arms, called spars • The trailing edge of each blade is covered with a sturdy graphite composite material, while the leading edge is made of titanium.

  7. APACHE HELLFIRE MISSILES • Miniature aircraft • Complete with its own guidance computer • Steering control and propulsion system. • Payload is a high-explosive, copper-lined-charge warhead. • Laser Seeking System.

  8. DRAWBACKS OF HELLFIRE MISSILES • Cloud cover or obstacles • Laser should be fixed on the target until the missile makes contact • Vulnerable to attack.

  9. HELLFIRE-II MISSILE • Used in Apache Longbow helicopters • The missile has a radar seeker

  10. Apache Rockets and Chain Gun • Fly with two Hydra rocket launchers • Each rocket launcher carries 19folding-fin 2.75-inch aerial rockets • The gunner engages close-range targets with an M230 30-mm automatic cannon • The automatic cannon is a chain gun design, powered by an electric motor

  11. Apache Controls Collective and cyclic controls Digital stabilization system Mechanical hydraulic system

  12. Apache Sensors • Radar dome • Radar signal processor • Night Vision Sensors(Forward-Looking Infrared (FLIR) System)

  13. Apache Evasion Tactics and Armor • Radar jammer • Evade heat-seeking missiles • The Black Hole infrared suppression system • Infrared jammer • Kevlar soft armor • Cockpit is protected by layers of reinforced armor and bulletproof glass

  14. Turbo-Shaft Engine • Reduced Engine Refueling • More Reliability and Better Performance • Lower Maintenance Costs, Longer Engine Life

  15. APACHE HELICOPTER AERODYNAMIC FORCES • THRUST • DRAG • WEIGHT • LIFT

  16. Armaments and configurations

  17. Conclusion • With the design of the apache the very concept of helicopter itself has changed all over the world. Many countries like Russia, Germany etc. have rolled over their versions of attack helicopters. They replaced the main drawbacks of apache. But it can be surely emphasized that the Apache is the pioneer in the attack helicopter family.

  18. THANK YOU
