Abstract

To perform effective integration test of avionics equipments, the importance of a setup for integration test environment has been increasing in recently developed aircraft. Especially, the development of integration test equipment is necessary for minimizing the development period and reliability of integration test. This paper treats the model development for optimal working of integration test after analyzing the characteristics of each MEP equipments for Surion(KUH). Models, whose main role is troubleshooting of equipment and simulation for missing equipments, consists of dynamic, behavior, and ICD models depending on the dynamic characteristics. Software test for both unit level and system level are performed to verify the model reliability. By conducting integration test using SIL, it is confirmed that the developed models are suitable for integration function test of the MEP system.

최신항공기 개발에서 증가추세에 있는 항공전자 장비들의 효율적인 통합시험 수행을 위 해 통합시험환경구축이 중요한 역할을 하고 있다. 특히 개발기간 최소화 및 신뢰성과 신속한 통합시험수행을 위해 통합시험장비 개발이 필수적이다. 본 논문에서는 수리온(KUH) 임무탑재장비(MEP)의 각 장비별 특성을 분석 후 최적의 통합시험 수행을 위한 장비별 모델개발을 다루었다. 모델은 동작특성에 따라 동적(Dynamic), 행동(Behavior), 연동(ICD) 모델로 구분하였으며 장비의 고장탐구 및 미장착된 장비의 동작특성 모사가 모델링의 주목적이다. 모델은 소프트웨어 단위시험 및 체계 통합시험 두 단계로 나누어 객관적 신뢰성을 검증하였다. 수리온 MEP 통합시험장비(SIL)를 이용하여 개발된 모델을 통합시험에 적용한 결과 설계 목적에 부합됨을 확인하였다.
