초록

지상 조건에서 우주비행체의 기동 및 자세제어 로직을 검증하기 위한 일반적인 방법으로는 우주비행체 설계단계에서 비행 소프트웨어를 이용한 시뮬레이션과 우주비행체 조립 후 시스템 수준에서의 통합 기능시험이 있다. 최근에는 소형화 및 정밀화된 부품들을 사용함으로써 지상에서도 시뮬레이터의 구동을 통해 우주비행체의 기동 및 자세제어 로직을 검증하는 연구가 활발하게 진행되는 추세다. 본 연구에서는 우주비행체 시뮬레이터의 개념설계 수행시 필요한 기초 데이터를 도출하기 위해 시뮬레이터용 냉가스 추진시스템에 대한 연구개발 동향 및 주요 성능 특성에 대해 조사하였다.

In general, such ground based methods are utilized to validate maneuvering and attitude control logics of a spacecraft by a simulation with a flight software at a design phase and a integrated function test with actual hardwares at a system level. Recently, varification researches using operating simulators are getting increase using compact and precise components under a ground condition. The present paper investigates and summarized the development trend of cold gas propulsion systems for the spacecraft simulators and their major performance characteristics to derive fundamental data which are necessary for a conceptual design of the simulator.
