| 摘 要： | 航空发动机的不断发展,使涡轮前的温度越来越高.尽管材料科研发展迅速,但仍赶不上温度提高的要求,涡轮叶片必须采用气冷,这就对涡轮气动性能带来了影响.本文介绍了用平面叶栅吹风试验方法研究气膜冷却叶栅在各种工况下对叶栅气动性能的影响,获得了许多有价值的结论.

| Abstract: | With the development nf aero-eogine, the turbine inlet temperature is getting higher. High inlet temperature generally results in thick trailing edge with the present and expected material limitations. Turbine blades are cooled with secnndary cooling air, which has influence on turbine aerodynamic perfnrrnauee. This paper has investigated the influence of blade surface ejection on aerodynamic performance of turbine cascade at the difl~reut blowing ratio. |
