1. 제 목 : Dynamics and Control of Large Solar Sail Spacecraft
2. 연 사 : 위 봉 교수 (Arizona State University)
3. 일 시 : 2003년 5월 12일 (월) 16:00 - 17:00
4. 장 소 : 서울대 신공학관(301동) 117호 세미나실
5. 내 용 :
Recent study results for developing dynamic models and attitude control systems of large solar sail spacecraft propelled by solar radiation pressure force are presented. The study objective was to advance solar sail attitude and flight control technology so that a solar sail flight experiment for validating sail attitude stability & controllability and thrust vector pointing & steering performance can be conducted within the next 5 years. Various dynamic models and conceptual control design options are developed for a sail attitude control system employing spin stabilization, reaction wheels, a two-axis gimbaled control boom, control vanes, and/or sail panel translation & rotation. A brief historical overview of solar sailing as well as near-term solar sail missions currently envisioned by NASA are also presented in this seminar.
