美欧政府部门和制造商正迅速开发新兴的金属基复合材料(MMC)技术,以提高燃气涡轮发动机的性能.今年8月初,美国制造商、美国空军(USAF)和预研计划局(ARPA)决定投资2.16亿美元,用5年时间,到本世纪末建立起一个航空发动机用MMC的工业生产基地.去年9月,欧洲制造商及所在国家国防部启动一项为期4年、投资800万英镑(1200万美元)的计划提高MMC性能及其生产技术.美国的MMC计划分为3个阶
U.S. and European government agencies and manufacturers are rapidly developing emerging MMC technology to improve the performance of gas turbine engines. In early August this year, U.S. manufacturers, USAF and ARPA, Decided to invest 216 million U.S. dollars in a five-year period to establish an industrial production base for MMCs for aeroengines by the end of this century. In September last year, European manufacturers and their respective national defense ministries launched a four-year project to invest £ 8 million 12 million US dollars) plan to improve the MMC performance and production technology.The United States of America MMC plan is divided into three steps
