초록

달 착륙선 개념설계형상 검증모델은 한국형 달착륙선의 진보된 우주 비행체 기술들의 개발 및 검증을 위한 시험베드로서 개념설계형상을 바탕으로 달과 지구의 중력 차이를 고려하여 실제 중량의 1/6 스케일로 설계된 수직이착륙이 가능한 달착륙선의 프로토타입이다. 검증모델은 지상에 고정된 상태에서 추력기 클러스터링 시험과 가상비행시험을 수행하였다. 검증모델 지상시험은 두 달 동안 고흥항공센터 고체모터연소 시험장에서 진행했다. 검증모델의 지상시험의 목적은 비행모델 탐사선의 개발 이전에 주요 전자장비, 200N급 추진시스템, 제어 알고리즘 및 소프트웨어, 구조체의 핵심기술 및 체계운용기술 등의 전체 시스템에 대한 시연 및 검증이다. 본 논문에서는 시험형상, 시험목적 그리고 시험제반시설에 대한 기술을 포함한 가상비행시험에 대한 내용을 기술한다.

The conceptual design lunar lander demonstrator has been developed to use as a test bed for advanced spacecraft technologies and to test a prototype planetary lander capable of vertical takeoff and landing. Size of the lunar lander demonstrator is the same as that of lunar lander conceptually designed, however, the weight of lunar lander demonstrator is designed in 1/6 scale in consideration of gravity difference between moon and earth. The thruster clustering and virtual flight test were performed in the demonstrator fixed on the ground. The demonstrator ground test has been conducted for two months in the test site for the solid motor combustion of the Goheung Flight Center. The purposes of ground test of demonstrator are to demonstrate and verify essential electronics, propulsion system, control algorithm, embedded software, structure and system operation technologies before developing the flight model lander. This paper is described about the virtual flight test including test configuration, test aims and test facilities
