摘要
Abstract
The problem of optimal design of a multi-gravity-assist space trajectory with deep space maneuvers is studied. Based on the zero-sphere-of-influence and patched conic hypothesis, the deep space trajectory is split into segments linked by deep space maneuvers and gravity assists. After introducing an auxiliary angle and B plane, the outgoing excess velocity could be expressed analytically. The deep space maneuver was computed by solving Lambert problem and trajectory propagation. The differential evolution algorithm is used to handle afore mentioned global optimization problem. Three cases to Jupiter, with gravity sequences of Venus-Earth-Earth (VEE), Venus-Earth-Mars-Earth (VEME) and Venus-Earth-Venus-Earth (VEVE) have been optimized.关键词
