本文研究利用不同飞行状态下测量的发动机变量估计涡轮进口温度和压气机出口压力。参数估计法采用多元线性回归分析法。根据变量选择的综合最优原则 ,从 6个测量变量中选择了回归方程的自变量 ,建立仅包含 3个发动机测量变量的回归模型 ,参数估计结果证明模型的估计精度是满意的。本文还介绍了利用专用设备在线录取发动机变量的数据处理方法。 This paper studies the use of engine variables measured under different flight conditions to estimate the turbine inlet temperature and the compressor outlet pressure. Parameter estimation method using multiple linear regression analysis. According to the comprehensive optimization principle of variable selection, the independent variables of the regression equation are selected from the six measurement variables, and a regression model containing only three engine measurement variables is established. The parameter estimation results show that the estimation accuracy of the model is satisfactory. This article also describes the data processing method for on-line admission of engine variables using specialized equipment.
