飞机改装供配电技术研究

随着科技日新月异地发展,飞机电源系统由低压直流电源系统向交流电源系统、高压直流电源系统转变,用电功率也随着机载设备用电量的增加和航电设备现代化程度的提高而迅猛增大。文章从近几年新型飞机设计定型试飞和新型产品鉴定试飞改装两个方面,研究了在不同型号的飞机上加装不同型号的设备时,飞机改装常用的几种供配电设计方法,并分析了这些方法对飞机自身供配电系统的影响。

With the rapid development of science and technology, the aircraft power system has been transformed from a lowvoltage DC power system to an AC power system and a high-voltage DC power system. The power consumption has also increased rapidly with the increase in power consumption of on-board equipment and the modernization of avionics equipment. This paper studies several power supply and distribution design methods commonly used in aircraft modification when different types of equipment are installed on different types of aircraft from the two aspects of new aircraft design finalization test and new product identification test flight modification in recent years, and describes the impact of these methods on the aircraft’s own power supply and distribution system.
