摘　　要：通过对某型发动机动力装置相关系统飞行试验数据的统计,初步总结了该型飞机动力装置的部分操纵及供油规律。研究发现,当在不同高度上等速爬升及平飞时,油门杆操纵及相应的速度、燃油流量具有不同的变化趋势;当进行等马赫数爬升时,相应的油门杆操纵及燃油流量变化趋势则彼此接近;燃油流量与高压压气机后压力之比主要随油门杆操纵的变化而变化,受高压压气后总温的影响比较小。Based on the statistics of flight data of a certain type of engine power plant, some manipulations and fuel supply rules of the power plant of the aircraft are summarized in the paper. It is found that when the aircraft is climbing at different heights and flying at the same level, the throttle lever manipulation and the corresponding speed and fuel flow have different trends. When the aircraft is climbing at equal Mach number, the corresponding throttle lever manipulation and fuel flow change tendency are close each other. The ratio of the fuel flow rote to the pest-pressure of the high-pressure compressor mainly varies with the change of the throttle lever manipulation, and the influence of the total temperature after the high-pressure compressor is relatively small.
