摘要
为适应涡轮在变工质，大变工况条件下的性能预测，研究了工质的性质，涡轮各种损失与涡轮流通通道内的临界堵塞流动，变几何涡轮的性能计算方法。这些研究的结果是变几何变工质涡轮理论分析的有用工具。
ngine in space shuttle works in variable condition, from Mach number zero to Machnumber 3￣ 3. 5. So turbine works at off-design condition. The performance of engine is dependent oncharacter of turbine at off-design. The variable geometric turbine is an effective method of increasingefficiency and improving match of turbine with other parts of engine. In this paper, the calculatingmethod of medium property, turbine loss and critical flow condition, and the characteristics of variablegeometry turbine are researched. These method are useful for design and analysis of variable geometricturbines.
