涡轮是航空发动机的重要高温部件之一。提高航空发动机性能的主要途径就是提高涡轮前温度。现在先进的航空发动机的涡轮前温度超过了大部分现有材料所能够承受的最高温度。因此为了保证发动机的正常使用,研究各种冷却结构和各种冷却方式对涡轮部件的冷却效果有利于提高航空发动机的工作效率。为了有效地冷却高压涡轮盘和转子叶片,往往采用预 Turbine aircraft is one of the important high temperature components. The main way to improve aeroengine performance is to increase the turbine’s pre-turbine temperature. Today’s advanced aero engines have turbine front temperatures that exceed the maximum temperatures that most existing materials can withstand. Therefore, in order to ensure the normal use of the engine, it is helpful to improve the working efficiency of the aeroengine by studying the cooling effect of various cooling structures and various cooling methods on the turbine components. In order to effectively cool the high-pressure turbine disk and rotor blades, often used pre-
