在燃气涡轮研究所 ( GTE)的涡轮叶片综合冷却效果试验器上对四套大载荷跨音速复合式气冷涡轮叶片 (多种气膜孔方案 ) ,成功地进行了 2 90小时试验。试验结果表明 ,导叶在 2 - 8% ,动叶在 1- 6%宽广的冷气流量比范围内 ,具有良好的冷却特性。此外还分析了叶片参数对冷却效果的影响
In the Gas Turbine Institute (GTE) turbine blade integrated cooling effect tester for four sets of large-load transonic hybrid air-cooled turbine blades (a variety of film hole scheme), successfully carried out 2 90-hour test. The test results show that the guide vanes have good cooling characteristics at a flow rate ratio of 2 to 8% and moving blades at a wide air flow rate of 1 to 6%. In addition, the influence of the blade parameters on the cooling effect is also analyzed
