民用飞机辅助动力装置起动电气系统研究

辅助动力装置系统的主要作用是为飞机在地面和空中提供备用电源并为发动机起动及环控系统提供气源。起动系统作为辅助动力装置系统的重要组成部分,是保证APU正常工作的前提条件。对辅助动力装置起动系统几个典型构型的电气原理和电气接口进行了介绍和分析,并通过对各种电气设计的对比,分析得出民用飞机在辅助动力装置起动系统电气设计上的发展方向,为民用飞机辅助动力装置起动系统设计方案的选择提供参考和借鉴

Research on APU Start Electrical System for Civil Aircraft

The primary function of the auxiliary power unit system is to provide a standby electrical power while airplanes being in the air and on the ground, and to bleed air for engine start and environmental control system. As an important part of auxiliary power unit system, the start system is a guarantee of APU system to work normally. The electrical principle and electrical interface of APU start system on three typical configurations are introduced and analyzed. compared with all kinds of electricaldesign, the results show the development direction of the electrical design based on the APU start system for civil aircraft. The research can provide useful reference for APU startsystem design scheme in civil aircraft.
