Tthe 록히드 AH-56 샤이엔 록히드가 미국 육군을 위해 개발한 공격 헬리콥터였다. 육군의 AAFSS (Advanced Aerial Fire Support System) 프로그램에서 서비스 최초의 전용 공격 헬리콥터를 배치했습니다. 록히드는 4 블레이드 강성 로터 시스템을 사용하여 Cheyenne을 설계하고 항공기를 제너럴 일렉트릭 T64 터보 샤프트 엔진에 의해 구동되는 낮은 장착 날개와 꼬리 장착 추력 프로펠러가있는 복합 헬리콥터로 구성했습니다. Cheyenne은 Bell UH-1 Iroquois와 같은 육군의 수송 헬리콥터에 무장 호위를 제공 할 수있는 고속 대시 능력을 갖추고있었습니다.

General Characteristics and Role
The Lockheed AH-56 Cheyenne was an advanced attack helicopter developed for the United States Army as part of the Advanced Aerial Fire Support System (AAFSS) program during the Vietnam War era. It featured a revolutionary design, combining the agility of a helicopter with the high speed of a fixed-wing aircraft. The Cheyenne utilized a rigid rotor system and a pusher propeller to achieve speeds far greater than conventional helicopters of the time. The aircraft incorporated a sophisticated stabilized gun turret and a separate crew station for the gunner, with the commander/pilot located behind. Though highly innovative and setting several speed records, the program was ultimately canceled in 1972 due to political infighting, high costs, and technical complexity, paving the way for the eventual development of the AH-64 Apache.

Powerplant and Performance
- Engine: One General Electric T64-GE-16 turboshaft engine.
- Power Output: 2,927 kW (3,925 hp).
- Propulsion System: Combined main rotor, anti-torque tail rotor, and a 3-bladed auxiliary pusher propeller (providing forward thrust at high speeds).
- Maximum Speed: 393 km/h (244 mph; 212 kn) (Self-imposed limit; capable of higher speeds).
- Range: 1,955 km (1,215 mi; 1,055 nmi).
- Unique Feature: Employed a Lockheed rigid rotor system which allowed it to transition smoothly between helicopter and autogyro flight modes, greatly enhancing high-speed stability.
Armament and Fire Control
- Armament System: Featured a chin-mounted turret with a 30 mm M129 grenade launcher or 40 mm XM140 grenade launcher, and a belly-mounted 30 mm XM52 cannon turret (operated by the gunner).
- Weapon Stations: 6 underwing hardpoints for rockets and missiles. Typical load included:
- Hydra 70 rockets.
- TOW anti-tank guided missiles.
- Fire Control: Incorporated an advanced, stabilized gunner’s station, allowing the gunner to rotate 360 degrees and aim independently of the helicopter’s direction of flight. The gunner’s seat rotated with the turret.
- Fate: Despite its advanced capabilities, the AH-56 was deemed too complex and expensive, leading to the cancellation of its production contract in 1972.
