Boeing AH 6. 4 Apache Wikipedia. The Boeing AH 6. Apache is an American four blade, twin turboshaftattack helicopter with a tailwheel type landing gear arrangement and a tandem cockpit for a two man crew. It features a nose mounted sensor suite for target acquisition and night vision systems. It is armed with a 3. M2. 30 chain gun carried between the main landing gear, under the aircrafts forward fuselage, and four hardpoints mounted on stub wing pylons for carrying armament and stores, typically a mixture of AGM 1. Hellfire missiles and Hydra 7. The AH 6. 4 has a large amount of systems redundancy to improve combat survivability. The Apache originally started as the Model 7. Hughes Helicopters for the United States Armys Advanced Attack Helicopter program to replace the AH 1 Cobra. The prototype YAH 6. September 1. 97. 5. The U. S. Army selected the YAH 6.

Army service in April 1. The first production AH 6. D Apache Longbow, an upgraded Apache variant, was delivered to the Army in March 1. Production has been continued by Boeing Defense, Space Security over 2,0. AH 6. 4s have been produced to date. The U. S. Army is the primary operator of the AH 6.

Key West Agreement forbade the Army from owning combat fixed wing aircraft. The Army wanted an aircraft better than the AH 1 Cobra in firepower, performance and range. It would have the maneuverability for terrain following nap of the earth No. E flying. 8 To this end, the U. S. Army issued a Request For Proposals RFP for an Advanced Attack Helicopter AAH on 1. Mi 24 Helicopter Game' title='Mi 24 Helicopter Game' />November 1. As a sign of the importance of this project, in September 1. Army designated its five most important projects as the Big Five, with the AAH included. Proposals were submitted by Bell, Boeing VertolGrumman team, Hughes, Lockheed, and Sikorsky. In July 1. 97. 3, the U. S. Department of Defense selected finalists Bell and Hughes Aircrafts Toolco Aircraft Division later Hughes Helicopters. This began the phase 1 of the competition. Each company built prototype helicopters and went through a flight test program. Hughes Model 7. 7YAH 6. How To Install Windows Xp Black Edition Sp3 From Usb. A prototype first flew on 3. September 1. 97. 5, while Bells Model 4. YAH 6. 3A prototype first flew on 1 October 1. After evaluating the test results, the Army selected Hughes YAH 6. A over Bells YAH 6. A in 1. 97. 6. Reasons for selecting the YAH 6. A included its more damage tolerant four blade main rotor and the instability of the YAH 6. A YAH 6. 4A prototype in 1. The AH 6. 4A then entered phase 2 of the AAH program under which three pre production AH 6. YAH 6. 4A flight prototypes and the ground test unit were upgraded to the same standard. Weapons and sensor systems were integrated and tested during this time, including the laser guided AGM 1. Hellfire missile. Development of the Hellfire missile had begun in 1. Helicopter Launched, Fire and Forget Missile Hellfire being a shortened acronym,1. Into productioneditIn 1. AH 6. 4As were handed over to the U. S. Army for Operational Test II. The Army testing was successful, but afterward it was decided to upgrade to the more powerful T7. GE 7. 01 version of engine, rated at 1,6. W. The AH 6. 4 was named the Apache in late 1. Armys traditional use of American Indian tribal names for its helicopters and it was approved for full scale production in 1. In 1. 98. 3, the first production helicopter was rolled out at Hughes Helicopters facility at Mesa, Arizona. Hughes Helicopters was purchased by Mc. Donnell Douglas for 4. The helicopter unit later became part of The Boeing Company with the merger of Boeing and Mc. Donnell Douglas in August 1. In 1. 98. 6, the incremental or flyaway cost for the AH 6. A was 7. M and the average unit cost was approximately 1. M based on total costs. During the 1. 98. Mc. Donnell Douglas studied an AH 6. B, featuring an updated cockpit, new fire control system and other upgrades. In 1. 98. 8, funding was approved for a multi stage upgrade program to improve sensor and weapon systems. Technological advance led to the programs cancellation in favor of more ambitious changes. In August 1. 99. 0, development of the AH 6. D Apache Longbow was approved by the Defense Acquisition Board. The first AH 6. 4D prototype flew on 1. April 1. 99. 2,2. April 1. 99. 5. During testing, six AH 6. D helicopters were pitted against a numerically superior group of AH 6. A helicopters the results demonstrated the AH 6. D to have a seven times increase in survivability and four times increase in lethality compared to the AH 6. A. 2. 42. 52. On 1. October 1. August 1. AH 6. 4As to AH 6. D standard. 2. 8 On 1. March 1. 99. 7, the first production AH 6. D first flew, it was delivered on 3. March. 2. 9Portions of the Apache are produced by various aerospace firms. Agusta. Westland has produced number of components for the Apache, both for the international market and for the British Armys Agusta. Westland Apache. 3. Since 2. 00. 4, Korea Aerospace Industries has been the sole manufacturer of the Apaches fuselage. Fuselage production had previously been performed by Teledyne Ryan Aeronautical the transfer of fuselage production led to a prolonged legal dispute between Teledyne Ryan and Boeing. The AH 6. 4D program cost a total of 1. In April 2. 00. 6, Boeing was awarded a 6. M fixed price contract for the remanufacture of several existing U. S. AH 6. 4As to the AH 6. D configuration between May 2. July 2. 01. 1, a further five contracts were issued to remanufacture batches of AH 6. As to the upgraded D variant. Since 2. 00. 8, nations operating the older AH 6. A have been urged to undertake modernization programs to become AH 6. Ds, as Boeing and the U. S. Army plans to terminate support for the A variants in the near future. OvervieweditThe AH 6. Apache has a four blade main rotor and a four blade tail rotor. The crew sits in tandem, with the pilot sitting behind and above the co pilotgunner. Both crew members are capable of flying the aircraft and performing methods of weapon engagements independently. The AH 6. 4 is powered by two General Electric T7. Various models of engines have been used on the Apache those in British service use engines from Rolls Royce. In 2. 00. 4, General Electric Aviation began producing more powerful T7. GE 7. 01. D engines, rated at 2,0. W for AH 6. 4Ds. 4. The crew compartment has shielding between the cockpits, such that at least one crew member can survive hits. The compartment and the rotor blades are designed to sustain a hit from 2. The airframe includes some 2,5.
