木星探査ミッションのためのΔV-EGAおよびVEGA軌道の一般的特性

抄録

In the trajectory design to Jupiter, various interplanetary flight modes have been investigated. In this paper, the general characteristics of two interplanetary flight modes, that is, deep space ΔV-Earth gravity assist trajectories and Venus-Earth gravity assist trajectories, are considered. Each mode is evaluated in terms of required ΔV and flight time, and the periodicity of the launch opportunity for each mode is classified. Also, the solutions are obtained by a new trajectory generation method which seeks the optimal trajectories including the intermediate impulses and the powered swingbys.
