美国各公司,在发动机技术方面,尤其在为战斗机、直升机和装甲车辆配套的发动机技术方面,正在取得重大成就。与目前的军用发动机相比,美军未来的发动机推重比将更大,油耗将更小,可靠性将更高,且便于维修。 一、战斗机发动机方面的最新进展1.高级战术战斗机的发动机方面 最近,在这方面最引人注目的进展是:普拉特与惠特尼动力公司（Fratt and whitneyCo.）和通用电气公司（General Electric Co.）分别为美国空军F-119高级战术战斗机和F-120级战术战斗机配套的飞机发动机。这两种发动机现分别安装在洛克希德—波音—通用动力公司
U.S. companies are making significant achievements in engine technology, especially in engine technologies that complement fighter planes, helicopters and armored vehicles. Compared with the current military engines, the future U.S. engines will have greater thrust-weight ratio, smaller fuel consumption, higher reliability and ease of maintenance. 1. Recent Developments in Fighter Engines 1. Engines for Advanced Tactical Fighter Platforms The most noticeable advances in this area are: Pratt and Whitney Co. and General Motors Electric Co. aircraft for the USAF F-119 Advanced Tactical Fighter and F-120 Tactical Fighter. These two engines are now installed in Lockheed - Boeing - General Dynamics
