民用飞机空气起动系统性能评估方法

摘要

根据民用飞机起动系统设计特点，分别给出了起动轴功率检查和起动机进口参数检查2种起动性能评估方法，并对2种方法进行了对比，起动轴功率检查方法可以直接反映起动机轴功率的设计状态；而起动机进口参数检查方法可以直接反映出起动关键参数（流量、总温和总压）的设计状态。最后，以某型辅助动力装置供气的起动性能计算为例验证了基于起动机进口参数的计算方法。%Based on starting system schematic and civil aircraft design characteristics, two performance evaluation methods were provided. One method is focusing on starter power, and the other is focusing on bleeding parameters of starter inlet. The starter power method is capable of indicating the design status of starting energy, while the bleeding parameter method is capable of indicating the status of key starting parameters (mass lfow, total temperature and total pressure). An example of APU bleeding starting performance evaluation using bleeding parameter method was also included in the paper. According to the experience of a certain domestic aircraft, both methods can be used in starting system design.
