摘要
对军民用大涵道比涡扇发动机的现状和发展趋势等进行了阐述,从国家大型飞机工程的战略目标、大型飞机发动机的重要性和市场前景等方面,对我国大涵道比涡扇发动机的需求、现状和差距进行了初步分析,简要介绍了我国大涵道比涡扇发动机的总体方案,提出了发展我国大涵道比涡扇发动机的主要关键技术,并分别从大涵道比涡扇发动机、国际合作、材料工艺试验条件建设等方面,简要论述了关键技术解决途径与措施建议.
The development status and trends of military and civil high bypass pressure ratio（BPR） turbofan engines for large airplanes has been summarized in the paper. In the aspects of strategical goals, importance and marketing foreground of the high BPR turbofan engines for national large airplanes engineering in China, the requirements, status and gaps of high BPR turbofan engines in China have been analysis briefly as well as the introduction of the overall engine scheme for the high BPR turbofan engines with the main key technologies for the engines. In terms of military and civil high BPR turbofan engines technologies, international cooperation, materials and techniques and test facilities, some suggestion and approach have been discussed for the technical challenges with the development of high BPR turbofan engines in China.
