以降低空间站为共轨飞行器补给燃料时补给机动的轨道面外冲量为目标,提出共轨飞行器位置部署分析方法.以光学舱作为共轨飞行器实例进行研究,在分析光学舱补给任务基础上,设计了补给变轨方案.基于虚拟平面思想提出了光学舱共轨部署的拟共轨轨道概念,推导了零面外机动条件下光学舱相对空间站升交点部署位置的一般解析计算模型,并在圆轨道假设条件下得到了简化解析计算模型,最终得到光学舱相对空间站的相位与升交点赤经部署模型.仿真结果表明,光学舱部署位置解析计算模型可以满足工程需求,不同相位条件下升交点赤经部署结果与数值解的相对误差小于3%,采用该解析方法进行光学舱位置部署后,补给任务轨道面外机动降低至原冲量的3.5%以下.%To solve the location deployment problem between the space station and the co-orbital spacecraft in the refueling mission, the process and the orbital transfer scheme were analyzed and designed on the basis of the calculation of J2 perturbation. A new orbital conception named quasi co-orbit was proposed based on the conception of virtual plane. In order to reduce the velocity out of the orbital plane, an analytic formulation used for calculating the orbital deviation was proposed. Based on the theoretical research, a location deployment model of the optical module which was considered as a typical example of co-orbital spacecraft was built and analyzed. The results of the numerical simulation proved the accuracy of the formulation and the calculation error was limited to 3 percent. The validity and accuracy of location deployment model were proved. It is demonstrated that the lo-cation deployment model is capable of providing estimation and guidance for the preliminary orbital design of the space station co-orbital optical module.
