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。
In order to reduce the out-of-plane impulse of maneuvering orbit maneuvering when the space station supplies fuel for the common-rail vehicle, a position analysis method of common-rail vehicle is proposed. Taking the optical cabin as an example of common-rail vehicle, the scheme of supply orbit change was designed based on the analysis of the optical cabin replenishment task. Based on the idea of virtual plane, the concept of pseudo-common-orbit in optical-rail common-rail deployment is proposed. The general analytical model of the deployment position of optical-satellite relative space station under zero-zero-plane maneuver is deduced and simplified under the assumption of circular orbit Analytical calculation model, the final phase of the optical capsule relative to the space station and ascending point of right ascension deployment model. The simulation results show that the calculation model of optical cabin deployment location can meet the engineering requirements. The relative error between the deployment results and the numerical solution of the ascending apex at different phases is less than 3%. After the deployment of the optical cabin, Surface mobility reduced to less than 3.5% of the original impulse.
