삼각형 태양돛의 주름저감 설계방안

국문 초록 (Abstract)

본 논문에서는 삼각형 태양돛의 주름저감설계 방안에 대한 연구를 수행하였다. 태양돛 멤브레인에 부분적으로 발생하는 주름으로 인하여 구조물의 추력성능과 제어성능에 영향을 받을 수 있으므로 멤브레인에 발생하는 주름을 감소시키거나 제거하는 것은 매우 중요하다. 주름을 저감하는 방법으로 태양돛 멤브레인과 붐을 연결하는 케이블의 하중의 각도를 조정하는 방식, 현수선 방식 및 현수선-와이어 방식을 고려하였으며 매개변수 연구를 통하여 주름저감효과에 대해 체계적으로 조사하였다.

In this paper, wrinkle reduction design was studied for triangular sail. Wrinkles in the solar sail membrane can change the load path and surface topology which may have an adverse effect on propulsion performance and controllability. In this study, wrinkle reduction strategies of adjusting cable angle, catenary and catenary-wire schemes were considered and the design parameters for wrinkle reduction were systematically investigated.
