摘要:In order to sufficiently realize the functions of Auxiliary Power Unit (APU) to an aircraft, it is very important to design a good APU control system. This paper was a research on the APU aircraft level control system design and discussed the aspects which should be consid- ered when control subsystems were designed, such as APU control panel, APU controller power supply, fuel control, emergency stop, APU air bleed, starter/generator, air inlet door control and indication/warning, etc. Some examples of design were provided and detailedly analyzed from the perspectives of function realization and electrical principle. This paper provided a recommendation for outline design and detail design of APU aircraft level control system.%为充分发挥APU(辅助动力装置)在民用飞机上的作用,设计一个好的APU控制系统显得尤为重要。对APU飞机级控制系统的设计进行了相关研究,论述了APU控制板、APU控制器供电、燃油控制、应急停车、APU引气、起动/发电、风门控制和指示告警等控制子系统在设计时所要考虑的因素,并给出了相应的设计样例,然后从功能实现和电气原理的角度进行了详细地分析,可为APU飞机级控制系统的方案设计提供参考。
