Abstract

This paper dealt with an alternative for maximizing mass savings in spacecraft design by replacing conventional aluminum alloy housing used for various spacecraft avionics by composite materials. Key requirements were defined for the purpose of composite housing design with sufficient durability and various functionalities as well as more lightweight characteristics as compared with aluminum alloy widely-used for conventional electronics housing. Conceptual design was also carried out for manufacturing modular, lightweight composite electronic housing equipped with high thermal and electrical conductivities, EMI protection, and radiation shielding characteristics as well as excellent structural performance; feasibility of enhancing mass savings in spacecraft design was presented.

본 연구는, 위성에 장착되는 각종 전자장비 하우징을 종래의 알루미늄 합금에서 복합재료로 대체함으로써 위성 경량화를 극대화할 수 있는 대안을 다루었다. 이를 위해, 기존 전자장비 하우징 재료로 널리 사용되는 알루미늄 합금에 비해 가벼우면서, 충분한 내구성과 다양한 기능성을 제공하는 복합재료 전자장비 하우징 설계를 위한 요구사항을 정의하였다. 또한, 열전도도, 전기전도도, EMI 보호, 방사차폐 특성과 더불어 강도가 우수한 구조적 특성을 갖춘 경량 복합재료 전자장비 하우징을 모듈화 방식으로 제작하기 위한 개념설계를 수행하고, 위성설계에 있어 무게절감을 크게 향상할 수 있는 가능성을 제시하였다.
