美国航空推进系统关键技术

在美国的国防关键技术计划中，航空推进技术受到重视。通过对美国国家级计划－－高性能涡轮发动机综合技术计划、脉冲式爆震波产生推力的新概念发动机计划、燃烧室内气流过渡为超声速的冲压发动机计划的研究，对美国选择推进系统的理由作了分析，并对各国在航空推进系统的研究和发展工作进行了评估。可以看出，日本、德国继美、英、法、俄后在航空航天的推进系统方面已完成了一系列的研究。日本斥巨资建立发动机模拟高空试验台。最后详细列出了燃气涡轮发动机，其它航空动力和燃料三类中的10项关键技术。

Key Technologies of American Aviation Propulsion Systems

Aviation propulsion technologies have been taken seriously in the key technology program of US national defense. The reason of selecting propulsion systems has been analyzed from an investigation on US national programs of Integrated High Performance Turbine Engine Technology, a new concept engine plan of pulse detonation engine, combustion chamber internal flow transition to supersonic ramjet engine. Also, evaluations have been made on research and development activities of aviation propulsion systems in different countries. Japan and German following USA, France and Russia have completed a series of studies on aviation and space propulsion systems. Japan has invested a huge sum on building up a simulated altitude test facility. At last ten items of key technologies in gas turbine engine, aviation power and fuel are listed in details.
