某型航空发动机在台架试车过程中多次出现加力接通延迟故障,本文主要介绍了该发动机加力燃油系统、喷口控制系统和加力接通电气控制系统的功能,重点描述加力接通过程的工作原理。根据其工作原理分析了产生该故障的可能原因,在此基础上对控制加力接通的电气系统进行了有针对性地分析,查找并排除了该故障。 This paper mainly introduces the function of this engine afterburner fuel system, the spout control system and afterburner electrical control system, focusing on the description of afterburner Through the process of working principle. According to its working principle, the possible causes of the fault were analyzed. On the basis of this, the electrical system for controlling the energizing was analyzed in a targeted manner, and the fault was found out and eliminated.
