阐述了应用均匀设计安排发动机性能试验并用回归分析模型处理试验数据的方法。强调了性能试验在航空发动机研制中的重要性,简要介绍了均匀设计的特点及其在试验设计中的优点,推导了用线性模型对试验数据回归分析的公式。文中示例性地用均匀设计表安排了涡扇发动机在高空模拟试车台上的性能试验,整理了试验数据,分析了试验结果,给出了一簇性能曲线。
The method to arrange engine performance test with uniform design and test data with regression analysis model is described. The importance of performance test in the development of aeroengine was emphasized. The characteristics of uniform design and its advantages in experimental design were briefly introduced. The formula of regression analysis of test data by linear model was deduced. In this paper, the uniform design of the table arranged turbofan engine performance test simulation platform in the high-altitude, finishing the test data, analysis of the test results, gives a cluster performance curve.
