| 摘 要： | 针对某1＋1／2对转涡轮进行了气动设计及流场分析。在设计中，以降低高压转子通道中激波损失为目标，低压级载荷系数选择了较高和较低两种方案。分析表明，虽然第二种方案可以降低高压转子出口马赫数，但该方案亦具有过渡段损失较大等劣势，故本文最终选择了第一个方案。利用该方案，本文完成了1＋1／2对转涡轮的气动设计并对该涡轮进行了三...

| Abstract: | The aerodynamic design and analysis of a Vaneless Counter-Rotating Turbine(VCRT) are presented.With the aim of decreasing the shock wave loss in HPTR,one scheme of the low pressure stage with relatively high load coefficient and another scheme of the low pressure stage with relatively low load coefficient are prepared.Though the second scheme can decrease the flow Mach number at the outlet of the high pressure rotor,it creases the loss greatly in the transition duct.So the first scheme is chosen.Under this ... |
