The purpose of this research work is to develop a computaion code of optimum trajectory analyzes with taking into account thruster performance and characteristics of electric propulsion. The code will be open to and be used for scientists and engineers engaged in space development and will help make space mission proposals and design space transportation systems.This analysis code is composed of an optimum low-thrust trajectory code and a performance alalysis code of electric thrusters. To verify the effectiveness of the performance analysis code, we investigated the effect of geometric design and operating parameters on the thruster performance of ion engines. Also, we developed three-dimensional ion beam optics code in order to evaluate ion engine life time. Calculated results were compared with measured results.The optimum low-thrust trajectory was developed as an improved version of that developed previously. We could convergent solutions with reduced computational cost and memory by the improved mathematical technique. Also, the code can be used to calculate optimum trajectories not only of interplanetary missions but also of the earth escape missions.

本研究工作的目的是开发一种考虑推进器性能和电推进特性的最佳弹道分析计算程序。该程序将向从事航天发展的科学家和工程师开放和使用，将有助于制定航天任务建议和设计空间运输系统。该分析程序由最优小推力轨迹程序和电推进器性能分析程序组成。为了验证性能分析程序的有效性，我们研究了几何设计和操作参数对离子发动机推进器性能的影响。此外，我们还开发了三维离子束光学程序来评估离子发动机的寿命。将计算结果与实测值进行了比较，得到了最优小推力弹道，并对其进行了改进。通过改进的数学方法，可以在减少计算成本和内存的情况下收敛解。此外，该代码不仅可以用来计算星际任务的最佳轨迹，也可以用来计算地球逃逸任务的最佳轨迹。
