某涡扇发动机加速性能试验研究

为了更好地研究某发动机加速性能,对发动机相关截面参数进行加改装,然后通过飞行试验,确定发动机稳定工作线。通过对加速过程发动机参数与稳态发动机参数的对比分析,研究发动机的加速性能,得到发动机加速过程存在的可改进空间,从而为后续发动机加速过程优化和试验提供指导。

Experimental Study on Accelerating Ability of a Turbo-fan Engine

In order to study the accelerating ability of a turbo-fan engine,the parameters of engine are converted.Then,the steady operating line of engine is determined by flight test.The accelerating ability of engine is studied by comparing the parameters of engine in accelerating process with the parameters of engine in steady state.The deficiencies of engine in accelerating process are gained,which can provide some reference for the test and optimization of engine in accelerating process.
