| 摘 要： | 为设计一种SRR结构具有大扩张通道的超音高载荷对转涡轮高压动叶，论文提出了一种更符合三维真实流动状态的S1流面三维造型法，详细阐述了三维造型方法基本原理，并用之设计了一个出口马赫数1.33，通道扩张角37.3°的超音高载荷对转涡轮动叶。三维数值模拟结果显示对转涡轮动叶流场参数分布合理，没有出现分离，滞止效率达到92.57%。实例表明三维造型法由于充分考虑涡轮流场三维性，对于通道扩张度大，流线曲率变化剧烈的涡轮叶片，比传统二维柱面造型法更精确、更实效。

| Abstract: | A new 3D profiles design method basing on S1 surfaces and more according with the true 3D flows in machinery, has been presented in the paper in order to design the rotor blades of supersonic highly loaded contra-rotating turbine(CRT) with large meridional flowpath divergence angle. The basic principle of 3D profiles design has been introduced detailedly and the high pressure rotor of supersonic highly loaded CRT with exit Mach 1.33 and meridional channel divergence angle 37.3°was designed. |
