Abstract

In this study, we proposed a nylon wire cutting-type solar panel separation mechanism for CubeSat applications using spring-loaded pogo-pins, which has been widely used as temporary electrical interface between two separate electronics. The mechanism proposed in this study has great advantages of higher holding capability, ability to constrain along in-plane and out-of-plane directions of solar panels, simplicity in tightening of nylon wire and synchronous separation of multiple panels. In addition, the pogo-pins used for the proposed mechanism act as electrical power interface, separation status switch and separation spring. In this study, the functionality of the proposed mechanism was validated through the separation tests with various number of nylon wire windings.

본 논문에서는 전기 접속부 역할을 하는 포고핀을 활용한 극초소형 위성용 나일론선 절단방식 태양전지판 분리장치를 제안하였다. 제안된 분리장치는 종래 나일론선을 이용한 분리장치에 비해 높은 체결력 및 횡/종방향 동시구속이 가능하고, 체결작업이 용이하며, 또한 다수의 태양전지판의 동시분리가 가능한 장점을 갖는다. 또한 제안된 분리장치에 적용된 포고핀은 전력공급을 위한 전기 접속부 기능과 함께 전개 상태 스위치 및 태양전지판의 분리 스프링 역할이 동시에 가능하다. 본 논문에서는 제안된 포고핀 분리장치의 기능성 입증을 위해 체결횟수에 따른 분리 기능시험을 통해 기능성을 검증하였다.
