摘要 针对航空发动机加力锁定功能需求,以AMESim为仿真平台,采用功能划分的方法对加力锁定功能模块进行分析,确定间隙泄漏是决定加力锁定功能的主要因素。制定了加力锁定控制设计方案,在加力锁定活门上增设密封件解决间隙泄漏;采用磨粒流去除衬套油路孔孔口尖边毛刺,调整加力锁定活门阻滞力,解决密封件过孔问题。实现了加力锁定功能,突破了现有技术限制,完成了技术创新,为航空发动机提供了一种实现加力锁定功能的解决方案。 Aiming at the locking requirements of aero-engine afterburner,using AMESim as the simulation platform,the locking module of afterburner was analyzed by the method of function division.It was found that gap leakage was the main factor that determined the locking function of afterburner.A design scheme for the locking control of afterburner was formulated,and a seal was added to the afterburner locking valve to solve the gap leakage.In order to solve through hole problem of the seal,the sharp edge burrs of hole ori⁃fice in bushing oil passage was removed by abrasive particle flow,and the blocking force of the locked after⁃burner valve was adjusted.Using the innovation method,the locking function of afterburner was achieved which could be provided as reference for aero-engine afterburning design.
