这 洛克希德AH-56谢延 是洛克希德公司为美国陆军研制的攻击直升机。它从陆军的高级空中火力支援系统（AAFSS）计划中崛起，派出了该部队的第一架专用攻击直升机。洛克希德公司使用四叶片刚性转子系统设计了谢延，并将飞机配置为低架机翼的复合直升机和由通用电气 T64 涡轮轴发动机驱动的尾装推力螺旋桨。谢延号将具有高速破折号能力，为陆军运输直升机（如贝尔UH-1伊罗奎斯）提供武装护航。

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.
