摘要
本文通过数值计算的方法研究插板式总压畸变试验技术。在总结已有试验的基础上,对试验中已完成和未完成的过程,都应用模拟计算的方法对进气道总压畸变的产生过程进行了仿真,并与试验数据进行了对比,。在此基础上,仿真分析了插板位置、插板高度、发动机转速对周向畸变指数的影响,分析结果可为试验提供一定的指导。
The numerical calculated method was used to research the technology of the total pressure distortion with flashboard. Based on the known experimentations, numerical method was used to study process of the inlet tptal pressure distortion, both the done and undone process in the experimentation. The result of the numerical simulation was contrast to the result of the experimentation. On the basic of this, this paper simulated study the infection of the different engine rotate speed , flashboard＇s position and height on the distortion. The analytic result can provide some guidance for the experimentation.
