Abstract

For the commercialization of unmanned aircraft, we must validate the safety of the air/ground collision alert systems (CAS). The validation procedure of CAS requires the flight test which is not only expensive but also dangerous. To alleviate this problem, we need the simulation based validation process for the CAS. We developed an integrated UAV simulation (IUS) environment which interconnect the flight simulator, the Matlab/Simulink, and a target avionics simulation model. We developed the collision warning module of the TCAS and tested using IUS and flight encounter models. Using IUS, we can evaluate the performance and reliability of a target avionic system at the preliminary design stage of a development life cycle.

무인기 상용화를 위해서는 유인기 수준의 안전성을 확보할 수 있는 공중 및 지상 의 충돌경보 및 회피시스템 (sense and avoid or SAA) 개발과 검증이 필요하다. SAA 검증을 위한 비행시험은 높은 시험비용과 사고위험 때문에 많은 시험사례(test case)를 검토하기 어려우므로 시뮬레이션 시험으로 보완하는 것이 필수적이다. SAA 시뮬레이션 시험을 위해 flight simulator, Matlab/Simulink 시뮬레이터와 항전장비 시뮬레이션 모델들이 서로 연동하는 통합 무인기 시뮬레이션 환경을 구축하였다. 사례연구로서 TCAS 충돌경보 simulink 모델을 개발하고 Flight Gear와 연동하여 통합 무인기 시뮬레이션 환경을 구축하였고 이를 encounter model을 이용하여 검증하였다. 통합 무인기 시뮬레이션 환경을 활용하면 항전장비 개발주기의 개념설계 단계부터 부품 및 시스템의 성능/신뢰성 분석을 시작할 수 있다.
