针对某飞行台某型被试发动机试验要求,设计研发了一套被试发动机引气负载控制及测量系统,介绍了该发动机引气负载系统的结构、控制方式及功能特点。该系统可实现对发动机各状态设计值范围内发动机的引气及控制监控,高低压级引气自动切换,引气量手动自动可调,其技术状态与装配原型机状态具有很好的一致性。
Aiming at the test requirements of a certain type of test engine for a flight test station, a set of engine bleed air load control and measurement system was designed and developed. The structure, control mode and function of the engine bleed air load system were introduced. The system can realize the engine bleed air and control monitoring within the designed value range of the engine, the automatic bleed air bleed at the high and low pressure levels, and the manual bleed air bleed can be automatically and manually adjusted. The technical status of the system is in good agreement with the state of the assembled prototype.
