摘要
本文对跨音速复合式气冷涡轮导向叶片陶瓷涂层隔热性能进行了试验研究。试验结果表明 ,叶片中截面净隔热效果为 167K,局部位置为 145～ 2 0 6K。并且 。
Thermal-barrier performance of composite air-cooled vane with ceramic coatings in a highly-loaded transonic turbine has been experimentally investigated.Experimental results show that the average net thermal-barrier effectiveness on the middle section of the coated vane is 167K,but the net thermal-barrier effectivenesses at some points are measured as 145-206K.The effects of gas temperature on thermal-barrier performance of ceramic coatings are also investigated.It is found that the performance is even better at a higher temperature or higher heat flux condition.
