摘要
为降低发射成本,充分利用运载能力,双星发射成为当前国际商用卫星发射普遍采用的一种发射方式。根据北斗导航系统组网需求,北斗导航系统中某类非静止轨道卫星要求采用一箭双星的发射模式,为适应双星发射需要,研制了卫星整流罩、卫星支架、仪器舱等重要结构。从设计原则、方案论证与比较、总体方案确定、系统级地面试验验证等4个方面对CZ-3A系列结构总体双星发射技术的研制现状进行总结,同时指出未来多星发射技术的发展方向,为后续双星乃至多星发射任务提供研制借鉴。
In order to reduce the launch costs, and to make full use of launch capacity, dual launch strategy is widely used in current international commercial satellite launch. Based on the networking requirements of BeiDou Navigation Satellite System, the dual launch mode is required by certain types of non-geostationary satellite. Some important components are created to meet the requirements of dual launch, such as the payload fairing, payload adapter, vehicle equipment bay, etc. In this paper, the development status of structure overall design over the dual launch technologies of the LM-3A series launch vehicle are summarized from four aspects, which including the design principles, the argumentation and comparison of scheme, the determination of overall scheme and the validation of system-level ground test. The development trend of multi-launch technologies are indicated, which will provide references and evidences for the research of future dual launch or multi-launch technologies.
