Abstract
Low-thrust technology is a key driver in current and upcoming space exploration missions due to their high specific impulse. A challenge when designing low thrust trajectories is due to the inherent coupling of the power and propulsion subsystems with the trajectory, as the spacecraft mass greatly affect the obtainable acceleration by a given propulsion subsystem. To this end, this work proposes an approach for coupling the sizing process of the power and propulsion subsystems to a direct-transcription-based trajectory optimization problem, which enables a concurrent trade-space exploration of both the trajectory and the spacecraft design.
