一代新材料,一代新型发动机:航空发动机的发展趋势及其对材料的需求

One Generation of New Material,One Generation of New Type Engine:Development Trend of Aero-engine and Its Requirements for Materials

在对世界航空动力技术加速发展态势进行简要综述的基础上,对航空发动机关键材料技术的发展现状与趋势进行分析研究,并按照一代新材料、一代新型发动机的思路,提出先进航空发动机主要部件和系统对材料技术的发展需求,并从质量稳定性和工艺成熟度、工程化研究和验证、材料体系和数据、复合材料、适航取证等方面,对提高我国材料技术的发展和应用水平提出了建议。

Based on the brief review of accelerated developing status of aircraft power technology in the world,the present status and developing trend of key materials technology for aero-engine were analyzed.In accordance with the idea of＂one generation of new material,one generation of new type engine＂,development requirements for the materials technology of the system and main parts of aero-engine were proposed.Suggestions for improving development and application level of the materials technology in China were presented from aspects of quality stability and technical maturity,investigation and verification for engineering,materials system and data,composite materials,airworthiness certificate,etc.
