在轨服务飞行器服务范围的定量分析

Quantitative analysis of the servicing space area of an on-orbit service vehicle

为了分析单艘在轨服务飞行器的最大服务范围,综合轨道动力学和球面几何学原理,利用经典二体动力学模型、霍曼转移轨道模型以及球面三角的几何关系,得出了一定机动能力的OSV(on-orbit service vehicle).从待机轨道出发,通过改变轨道平面和改变轨道高度能够到达的最大服务范围的计算方法,设计了不同高度、倾角和机动能力OSV服务范围的仿真算例,给出了直观的对比图,分析了服务范围与各种参数的关系和变化规律.该方法定量分析了单艘OSV的服务范围,指出该范围是三维空间中的轮环形空域,据此提出待机轨道的选择要使OSV的服务范围包含服务目标的运行轨道.

In order to attain the maximum servicing space area of a single on-orbit service vehicle（OSV）,an algorithm with which the OSV can be realized via the changing of its parking orbit plane and height with limited maneuverability was presented in this paper.The space dynamics and the spherical geometry were combined,and the classical twin-body dynamics,Hochmann transfer model,and spherical trigonal relationship were applied.Then,a simulation was designed to calculate the servicing area of the OSV at a different orbit height,inclination angle,and maneuverability,and an intuitionistic comparison graph was also plotted.Accordingly,the relationship and the variability between the servicing area and the different parameters were analyzed.The algorithm quantitatively analyzes the 3-dimensional annular space of the service area of a single OSV.It points out that the parking orbit of OVS should ensure that the target orbit be included in the servicing area.
