In this paper the research of the off-design performance calculation is presented forcooled turbine. When the turbine works at off-design, especially the cooling air is mixedinto gas flow, the gas flow is very complex in turbine. So as to it is suitable using theinviscid flow model, loss models, flow angle model and mixing model of cooling air and gasfor the performance calculation of cooled turbine. The calculation of critical flow, chockingand quality of mixed medium are considered.too. Several examples are calculated with thismethod. The results are satisfactory.
