摘要 对4个压气机中介机匣试验件进行了试验研究,包括原型、优化模型、支板根部前掠及流道延长4种方案.试验利用压力扫描阀及气动探针对试验件进出口总温、总压,上下壁面,大支板50%叶高处的静压进行测量,分析几何结构对中介机匣性能的影响.试验结果表明:增加流道轴向距离可提高中介机匣性能;优化后中介机匣壁面型线可改善进出口总压分布;下壁面型线对流动加减速有重要影响,优化后压力分布较平稳;优化需考虑支板影响. Four kinds of intermediate casings were tested experimentally, including the original model, optimization model, and two models based on optimization model respec tively. The length of the strut's chord and the flow path were changed for the last two mod els. Inlet and outlet total temperature, inlet and outlet total pressure, static pressure of outer and inner wall, static pressure of middle struct along 50% spanwise were measured by pneumatic intelligent pressure scanner and pressure probe, and the effects of the geometry structure on the intermediate casing's aerodynamic performance were evaluated. The results shows that: increase of the duct's axial distance can improve the performance of intermediate casing; the optimized intermediate casing profile can improve the pressure distribution in in let and outlet; the inner wall profile has a significant impact on the acceleration and decelera tion of flow, and optimized pressure distribution is relatively smooth; the geometry of the struts should be considered in optimization.
