起动机加速控制器供油规律分析与改进研究

Analysis and Mend of Start Accelerative Controller Supply Fuel Rule

针对起动机点火成功率低的问题,在分析飞机起动机加速控制器供油规律的基础上,提出了加速控制器的改进方案,通过安装不同流量控制器进行起动机燃气发生器转速及溢流压力特性试验,并对试验结果进行分析、研究和比较,确定了改进用最佳流量控制器。

To solve the question of starter retrofire failure rate, the paper analyzes aeroplane start accelerative con- troller supply fuel rule. It puts forward the technology of accelerative controller, try on start gas-fired rotate speed and liquid by fixing flow controller, compare the testing result, give the best flow controller.
