과학위성 1호 인증모델에 대한 발사환경시험 결과

Launch environmental test results of KAISTSAT-4 QM


초록

한국과학기술원 인공위성연구센터는 우리별 1, 2, 3호의 성공적인 개발 및 발사에 이어 2003년 발사예정으로 과학위성 1호를 개발하고 있다. 과학위성 1호는 주탑재체로 원자외선분광기와 우주플라즈마 관측시스템을 탑재하고 있으며, 우리별 1, 2, 3호의 기술적 유산인 박스형태의 적층식 기계수조로 설계되어 있다. 현재 과학위성 1호는 인증모델의 설계 및 제작과 인증수준의 열진공시험 및 발사환경시험을 성공적으로 마친 상태이다. 본 논문에서는 과학위성 1호 인증모델을 기계구조시스템을 중심으로 소개하고, 발사환경시험 결과를 보고한다.

KAISTAT-4 is the fourth experimental microsatellite of KITSAT series which has been developed by Satellite Technology Research Center of KAIST for the last two years. The launch of KAISTSAT-4 is scheduled in 2003. The primary experimental payloads consist of Far-ultraviolet Imaging Spectrograph and Space Physis Package. In a similar way to KITSAT series, the interior of KAISTSAT-4 comprises mainly a set of stacked aluminium-alloy module boxes, each being capable of acting as the primary load path in the mechanical structure. The KAISTSAT-4 qualification model is now designed, fabricated, integrated, and tested to verify if the electrical and mechanical components work and can withstand the launch environments. All the required structural tests have been performed to a sufficient degree to satisfy the intent of the test requirements. This paper presents the structural system and launch environmental test results of KAISTSAT-4 qualification model.
