一、引言 无论在飞机的研制还是在原型机的试飞中,都要求能迅速确定在飞行包线内任意一点上进气道/发动机的稳态匹配工作点。但是由于进气道时性本身的多变性,即它不仅随进气道几何形状,而且还随飞行Ma数、迎角。和侧滑角卢而变;而风洞试验却只能在上述变量的有限组合下进行。因此,对一个 I. INTRODUCTION No matter in the development of the aircraft or in the test flight of the prototype, it is required to be able to quickly determine the steady-state matching working point of the intake port / engine at any point in the flight envelope. However, due to the variability of the air intake itself, that is, it not only with the intake manifold geometry, but also with the flight Ma number, angle of attack. And sidelobe angle Lu; wind tunnel test but only in the limited combination of the above variables. So for one
