| 摘 要： | 先进的小发动机涡轮的流量小,叶片短,展弦比低,二次损失及叶尖漏泄损失大,效率低,温度高冷效差。与大发动机相比,尽管其工作原理相同,但它有其独特的矛盾,设计难度大,需作为一个独特的领域有组织有计划地开展设计研究工作。

| Abstract: | The advanced small gasturbines feature small mass flow ratio,short vanes and blades with low aspect, high second flow and blade tip leakage losses,and low efficiency.According to the detail investigation on the advanced small gas turbines,some technical design approaches for improving the efficiency of a small gasturbine,such as vanes with meridional-plane contraction contour,compounded leaned vanes and blades,small blade shroud and soon. |
