研究了基于2维等熵特征线理论的超声速涡轮叶栅设计方法，通过编程开发了超声速涡轮转子叶栅设计软件，该软件可根据进、出口马赫数及进口气流角设计出需要的超声速涡轮转子叶栅。在此基础上应用FLUENT详细地分析了涡轮转子叶栅流场。结果表明：该流场分布合理，未出现激波、分离等现象，且在高载荷系数下具有较高效率。

Supersonic turbine cascade design was studied based on two-dimensional isentropic characteristic theory. The supersonic turbine rotor cascade software was developed, which can design cascades by the inlet and outlet Mach numbers and the inlet flow angle. The turbine rotor cascade flow field was analyzed by FLUENT. The results show that the flow field is reasonable, shock-free and no separation and it have high efficiency under the high loadings.
