Abstract

In this paper, we propose a container wall and its boundary layer insulation design method that can maintain the temperature inside the spacecraft shipping container constantly under the condition that the heat or the external temperature changes severely to safely transport the satellite to the launch site. We will examine if the temperature inside the satellite shipping container is kept constant through the heat flow analysis and the satellite heat transfer analysis for the external environment of the satellite shipping container. Through the flow analysis inside the container, the flow distribution around the satellite in the container is analyzed, and the auxiliary fan, air conditioning system and special grill guide structure design for improving and optimizing heat flow performance are proposed.

본 논문은 위성을 발사장까지 안전하게 운반하기 위해, 열이나 외부 온도가 심하게 변화하는 조건에서 위성 컨테이너 내부 온도를 일정하게 유지할 수 있도록 컨테이너 벽면 및 경계층 단열 설계 방법을 제시하고 위성 운반용 컨테이너 외부 환경에 대한 열 유동 해석 및 위성 내부 열 전달 해석을 통해 위성 컨테이너 내부 온도가 일정하게 유지되는지 분석하였다. 컨테이너 내부 유동 해석을 통해 컨테이너 내 위성 주변의 유동이 원활 한지 유동 분포를 확인하였으며, 보조 팬 및 공조시스템과 특별한 그릴 가이드 구조 설계 안을 제시하고자 한다.
