| 摘 要： | 本文以无因次的导叶出口气流速度λ_1及动叶周速λ_(u1)为自变量,推导出超跨音涡轮级气流及性能参数的基本关系式,适用于基元级或以特征半径代表全级的性能预估。并随同给出一组举例的参数变化曲线。 也对近十年来国内外跨音涡轮研究情况作一简报,并以概括性能的压比效率图列出其水平。

| Abstract: | This paper derives a series of flow and performance parametric relations for supersonic and transonic turbine stages, using nondimensional nozzle vane exit speed i and rotor speed ui as independent variables. These formulas are applicable to elementary stages or to the whole stage repre sented at characteristic radii. Illustrative curves are given with one set of selected parameters.In addition, the recent developments of transonic and supersonic turbine research over the world are briefly reviewed, with the roles of various stages marked on an efficiency versus pressure ratio diagram. |
