摘要
燃油泵调节器供油特性的优劣,直接关系到航空发动机能否可靠工作和充分发挥性能。某燃气涡轮起动机燃油泵调节器,为满足用户使用要求,需改变其起动加速供油特性。主要通过增加数控模块,利用其控制器和传感器来实现信号的反馈与匹配,再通过放油实现脉宽调制电磁阀对流量的修正,从而实现对燃油泵调节器起动加速供油特性的修正。最后通过试验验证了改进方法的可行性。
Fuel pump regulator is the core member of aircraft engines; its fuel properties are directly relat-ed towhether the engine can operate reliably and make engine performance into full play. Based on a gas tur-bine starter fuel regulator for the research, the improved method of starting and acceleration fuel characteris-tics of the product was explained. Mainly through the method of pulse-width modulation（PWM） solenoidvalve, the starting fuel supply characteristics were modified. The feedback and matching of signal were real-ized by its controller and sensor. And the feasibility of improvement method was validated by test.
