Abstract

This paper describes a Power Monitoring Unit (PMU) for Unmanned Aerial Vehicle (UAV) electrical system, It is designed for the PMU which performs data sensing of generator, transformer rectifier unit (TRU), battery and gear box installed in UAV and operate power ON/OFF devices of mission equipment. The PMU measures the voltage and current for the aircraft power source (generators, transformer rectifier unit and battery), measures the pressure and temperature of the gearbox, and performs the mission equipment power command received from the mission computer. The PMU was designed to meet the requirements of the UAV, and was performed through structure/thermal analysis, environmental test, EMI test and ground/flight tests.

본 논문은 무인항공기 전기시스템을 위한 전원모니터링장치에 대해서 기술하고 있으며, 무인항공기에 장착되는 AC/DC 발전기, 전원변환기, 배터리 및 기어박스의 데이터 측정과 임무장비의 전원 ON/OFF 장치를 운용하는 전원모니터링장치에 대한 설계를 기술하였다. 전원모니터링장치는 비행체 전원(발전기, 전원변환기 및 배터리)에 대한 전압과 전류를 측정하고, 기어박스의 압력과 온도를 측정하며, 임무컴퓨터로부터 수신된 임무장비의 전원명령을 수행한다. 전원모니터링장치는 무인항공기 비행체 요구사항을 만족하도록 설계하였으며, 구조/열 해석, 환경/EMI 및 지상/비행시험을 통하여 검증을 수행하였다.
