| 摘 要： | 通过飞行试验得到的飞机机动性能,以及风洞试验得到的飞机气动性能,在常规飞机机动性能计算程序的基础上,提出了发动机高度速度特性反算计算模型,在这一模型中还包括一个将飞行试验测试数据转换模型,和发动机安装特性计算模型。对现役某些飞机进行模拟仿真,并与相应匹配的发动的高度速度对比表明,该计算模型合理。对以后通过飞行试验为发动机定型提供了新的理论依据,具有较好的工程应用价值。

| Abstract: | On the basis of computational model of flight dynamics, maneuvers performance achieved by flight experiment and dynamic performance of aircraft got by tunnel experiment. A reverse calculation model of engine performance of velocity and height is presented, as well as a diversion model for the experimental data and an installation model for engine performance. The calculation model applied on the simulation of aircraft is proved effective comparing to actually matched engine performance of velocity and heigh... |
