用试车数据检验某泵压液体火箭发动机动态特性非线性数学模型的准确度，考虑了发动机参数实际测量的误差范围。计算结果表明：在整个过渡过程中，所有可以实际测量的发动机参数的计算值与实测值之间的偏差均在±７．１％以内。
The test data is used to test the accuracy of a nonlinear mathematical model of the dynamic characteristics of a pumped liquid propellant rocket engine. The error range of the actual measurement of engine parameters is taken into account. The calculation results show that the deviations between the calculated and measured values of all the actually measurable engine parameters are all within ± 7.1% during the entire transition.
