The Lockheed AH-56 Cheyenne is an attack helicopter developed by Lockheed for the United States Army. It rose from the Army's Advanced Aerial Fire Support System (AAFSS) program to field the service's first dedicated attack helicopter.

ah-56最终成了自身标榜“超级战机”的受害者，并且为提出过的种种“高效承诺”付出了惨痛代价。 究其原因，主要是AH-56采用了当时并不成熟的技术，试验用原型机总是遇到技术瓶颈，火力强大、速度快“夏延”的优势，但缺乏稳定性、可操控性差等缺点也 ...

美国ah-56武装直升机 面对中欧的巨大的反坦克压力，以及日益严重的苏军机动防空火力（包括自行高炮和 防空导弹 ）和肩射防空导弹的威胁，美军开始探讨以贴地机动为主的直升机作战模式，这样，夏延的高速度就没有必要，而夏延有限的非常规机动能力就能 ...

上世纪60年代中期，美国陆军启动了 先进空中火力支援系统（AAFSS） 项目，该项目的目的是将洛克希德的AH-56夏延复合式武装直升机发展成一型 空中反坦克炮艇。 当时，美军的主力武装直升机尚且是被称为“临时工”的贝尔AH-1G眼镜蛇直升机。 尽管美军对眼镜蛇在中南半岛 丛林作战 中体现出的能力表示满意，但是从战略角度来说，他们更关注的仍然是 “如何对抗华约军团的钢铁洪流”。 AH-56夏延在立项之初被认为将会引领航空器领域的变革.

In 1966, Lockheed's design for an operational attack helicopter, the AH-56 Cheyenne, won the contract to build the US Army's Advanced Aerial Fire Support System (AAFSS). The Cheyenne had a 3,435 shp General Electric T64-GE-16 turboshaft engine that powered a rigid 50 ft four-bladed rotor, as well as a 10 ft three-bladed pusher propeller and a ...

On 15 November, the Cheyenne made its first cross-country flight to an airport Oxnard, California making a speed of 115 knots at 2,000 feet. The Cheyenne’s public debut occurred on 12 December with a thirteen minute flight.

The AH-56 Cheyenne is Lockheed's first and only foray into production helicopter development. In many ways, however, the Cheyenne is neither a true helicopter nor a true aircraftin many ways, today's tilt-rotor V-22 Osprey challenges traditional helicopter classifications.
