Scientific paper

A combined chemical and electric propulsion stages was used to solve a combined vehicle and mission optimization problem. The problem was solved by uncoupling the short-duration electric propulsion phases, thereby achieving a very efficient, robust approach. Various optimal vehicle-mission combinations were obtained for a range of transfer times from 16 to 500 days. Finally, a combined chemical-electric propulsion mission can provide an additional 15% payload capability compared to the corresponding all-chemical mission.
