服务型航天器共轨式轨道机动方式研究

随着航天器应用领域的不断扩大,在轨服务将有广阔的发展空间。当高价值的有人或无人航天器出现故障时,需要在最短的时间内获得在轨应急服务。本文首先根据未来服务型航天器提供应急服务面临的实际问题,分析研究了服务类型及其对响应时间的要求,其次建立了漂移式、组合式、直接弹道式3种共轨式机动模型,并给出了机动时间、能量、相位的关系式与仿真曲线。最后在此基础上,划分响应时间区间,根据该区间提出了选择机动方式的建议。

Study on Co-orbital Maneuver for Service Spacecrafts

With the increasing implementation of spacecrafts,the on-orbital service will have a wide developing space.When faults happen to high value manned or unmanned spacecrafts,the on-orbital service are needed in a short time.Firstly,according to the real problem faced by the future service in emergencies,the services is classified and the requirement of response time is discussed.Then,three co-orbital maneuver models are established,i.e.drifting model,combination model and direct ballistic trajectory model.The relationships between the time,the energy required in the maneuvers and the relative phase angle are formulated and their simulation results are presented. Finally,the response time is divided into several zones based on the results,and some suggestions are put forward about the option for maneuvers.
