Abstract

Solar sail propulsion uses solar radiation pressure to propel spacecraft without propellant, and it is useful for deep-space missions and continuos orbit maneuver missions. After a brief introduction of solar sail dynamics, locally optimal trajectories in Sun-centered and Earth-centered orbits are analyzed. Numerical simulations for the optimal trajectories are performed. Trajectory for the rendezvous with Halley comet is generated, and different planet escape methods are compared.

태양돛은 태양복사압을 이용하여 연료소모 없이 우주선에 지속적인 추력을 제공하는 방식으로, 심우주 임무나 지속적인 궤도기동이 필요한 임무에 적합하다. 본 논문에서는 태양돛의 기본 원리를 소개하고 태양중심, 행성중심 궤도에서의 국소최적제어 기법을 연구하였다. 각각의 최적제어 기법에 대한 시뮬레이션을 수행하였다. 핼리혜성 랑데부 궤적을 생성하였으며, 여러 가지 행성탈출 기법을 비교하였다.
