摘要
为提高载人飞船轨道设计的自动化程度和快速性,对自动化轨道设计方法进行了研究。分析了载人飞船不同阶段飞行轨道的约束条件,用约束条件首先确定了轨道的半长轴取值范围,由回归条件可确定回归圈数的取值范围;在给定的回归和返回条件下,迭代求解运行轨道的轨道半长轴与倾角;根据运行轨道设计结果,反推初始轨道和留轨轨道的轨道根数。自动化轨道设计方法对提高轨道设计效率与精度有一定的意义。
The automatic orbit design problem was researched in order to improve the automatic and rapid capability of spacecraft orbit design in this paper.The constraints in different phase of spacecraft were analyzed.The span of orbit semi-axis was determined using the contstrains,and the span of regressing circle was deduced by combining regressing condition.Under the regressing and returning conditions,the orbit semi-axis and inclination were solved using iterative method;and the other orbit roots could be deduced by using run-orbit roots at last.The research was useful for improving efficiency and accuracy of the orbit design.
