摘要
美国军方提出以现有发动机型号F119为基础来研制第四代轻型战机JSF,既降低了新机的技术风险,缩短型号研制周期,又可大幅度地节省项目研发资金和降低型号全寿命成本,这一思路值得关注或借鉴。通过对F-35战机基本型发动机F135和备用型F136发动机的最新发展动态分析,阐述了军用飞机动力装置类型从常规的涡喷/涡扇发动机向非常规的变循环发动机转变是一个必然发展趋势;而航空动力研制方法正从"传统设计"向更先进的"预测设计"过渡。
US army's way of developing the fourth generation light-weight fighter JSF on the basis of ex-isting F119engine is worth our attention and study,which has greatly reduced technical risks and lead time,saved development and full-life costs.Citing the latest progress of F-35baseline engine F135and the alternate one F136,this article outlines an inevitable trend of military aero engine development from conventional turbojet/turbofan to unconventional variable cycle engine,and aero-power plant development is gradually from'traditional design'to'prognostic design'.
