基于涡轴发动机相似理论,结合某样例直升机发动机的装机特点,对装机前后发动机转速NG-P特性进行了对比,对影响变化的因素进行了分析讨论,提出了针对具体的发动机装机位置、飞行状态、飞行环境进行综合装机功率损失的试验思路。
Based on the similar theory of turboshaft engine and the installation features of a helicopter engine, the NG-P characteristics of the engine before and after the engine are compared. The factors influencing the engine speed are analyzed and discussed. Aiming at the specific engine installed position, State, flight environment for integrated power loss test ideas.
