摘要
90年代,推重比10一级加力式涡扇发动机研制成功,推重比15～20的发动机预研计划使航空工业进入一个崭新的发展阶段.推重比10一级发动机的涡轮进口温度已达到1580℃～1680℃.美国国防部开展的“综合高性能涡轮发动机技术”(IHPTET)
The turbine inlet temperature of advanced military engine has reached 1850 ~ 1950K in 1990s, and will reach 2400K by 2020. In order to improve the engine performance, it is necessary to increase the turbine inlet temperature, which should use a lot of new turbine technologies. The paper mainly describes the aerodynamics design , structure design , blade cool technologies, new materials and new process , and testing technologies about the advance turbine.
