摘要
针对某型涡扇发动机试车过程中在应急状态喘振的故障,通过分析发动机结构和应急状态工作原理,研究在不使发动机进入喘振状态的前提下排查故障源的方法.研究表明,试车检查是检验故障是否排除的有效手段.提出人为干预发动机放气活门工作状态的方法,确保发动机试车过程中不会喘振,避免了发动机的二次损伤.该方法定位准确,对同类故障的排除具有一定的指导意义.
Abstract
In response to the fault of emergency surge during the testing process of a certain type of turbofan engine,this paper analyzes the engine structure and emergency working principle,and studies the method of identifying the fault source without causing the engine to enter a surge state.Research has shown that test drive inspections are an effective means of verifying whether faults have been eliminated.Propose a method of manually intervening in the working state of the engine exhaust valve to ensure that there is no surge during engine testing and to avoid secondary damage to the engine.This method has accurate positioning and certain guiding significance for troubleshooting similar faults.
