Abstract

Heating wire cutting type separation mechanism has been widely used for cube satellite applications due to its design constraints such as small size of $10cm{\times}10cm{\times}10cm$ and light weight of less than 1kg. In addition, usage of pyro technic device is not allowed for cube satellite application. The conventional methods have some disadvantages of relatively small mechanical constraint force and the system complexity for the multi-deployable systems. In this paper, a separation nut type non-explosive separation mechanism has been proposed and investigated. The effectiveness of the design has been verified through the qualification tests of the mechanism.

극초소형 위성으로 분류되는 큐브위성의 경우, 1U를 기준으로 $10cm{\times}10cm{\times}10cm$의 크기, 1kg 이하의 중량제한을 비롯해 폭발식 구속분리장치의 적용이 불가한 설계요구조건으로 인하여 열선 작동시 나일론선의 절단과 함께 구속을 해제하는 구속분리 방식이 일반적으로 적용되고 있으나 낮은 체결력과 다수 구조물의 구속 시 다수의 열선 적용을 필요로 하는 등 시스템 복잡화의 단점이 존재한다. 본 논문에서는 기존의 큐브위성에 적용되는 열선 절단방식의 단점을 극복하기 위하여 열선절단방식을 적용한 분리너트형 비폭발식 구속분리장치를 고안하였으며, 인증모델의 기능시험, 정하중시험 및 충격시험을 통해 설계 유효성을 입증하였다.
