초록

무인항공기는 자동모드에서는 사전에 계획된 항로점(비행이거나 이/착륙)들을 입력받아 자동으로 비행한다. 무인항공기는 수동모드에서도 유인항공기와 달리 조종사가 비행체에 탑승하지 않고 지상 통제실에서 조종입력을 인가하면 무선 데이터링크를 통하여 조종입력을 전달 받아 비행하게 된다. 데이터 링크는 여러 가지 이유로 통신두절이 될 수 있으며, 이때 무인항공기는 자동으로 비행모드를 수동에서 자동으로 전환하여 비행해야 한다. 그러므로 무인항공기에서 비행조종컴퓨터는 비행안전을 담당하는 매우 중요한 장비로 철저한 검증이 요구된다. 본 논문은 무인항공기의 비행제어컴퓨터가 비행성 요구조건을 만족하고, 다양한 고장이나 비상상황에서도 강건함을 입증할 수 있도록 비행제어 알고리즘의 검증환경인 HILS(Hardware In the Loop Simulation) 시험환경을 개발할 때 고려해야 할 사항들을 연구한 것으로 비행제어 HILS 시험환경의 구성장비들과 기타 고려사항 들을 제시한다.

A UAV(Unmanned Aerial Vehicle) flies along pre-programed navigation points(in-flight, take-off, or landing) automatically without pilot input. Even though UAVs fly differently from general piloted aircraft as the pilot controls the aircraft from a ground station through means of a data-link system. Occasionally, the data-link connection can be lost for any number of reasons, in which case, the FLCC(Flight control Computer) must automatically switch to autopilot to continue flying. Hence, the FLCC is a flight-critical component that must be throughly tested and validated. This paper discusses the development of a HILS(Hardware in the Loop Simulation) test environment designed to simulate real flight conditions to verify the FLCC satisfies flying quality requirements and maintains robustness despite any potential malfunctions or emergency situations.
