The invention relates to the technical field of spaceflight pressure containers, in particular to a spaceflight storage tank double-supporting-skirt flexible mounting structure which comprises an upper end fixing structure and a lower end fixing structure, and the upper end fixing structure is composed of an upper mounting ring and used for being connected with an upper supporting skirt of a spaceflight storage tank and a force bearing cylinder of a spacecraft; the lower end fixing structure comprises a movable track, a lower mounting ring, a spring set and a baffle and is used for being connected with a lower supporting skirt of a spaceflight storage tank and a force bearing cylinder of a spacecraft. The movable track and the baffle are welded and fixed, the lower installation ring is arranged between the movable track and the baffle in a sleeved mode, and the spring set is arranged between the lower installation ring and the baffle in a sleeved mode. The requirement for flexible installation of the double-supporting-skirt spaceflight storage tank is met, storage tank deformation and stress concentration caused by axial expansion and contraction in the working process of the spaceflight storage tank are greatly reduced, and the reliability of the double-supporting-skirt spaceflight storage tank installation structure under the launching and operation mechanical environment is guaranteed.

    本申请涉及航天压力容器技术领域,具体而言,涉及一种航天贮箱双支撑裙柔性安装结构,包括上端固定结构和下端固定结构,其中:上端固定结构由上安装环组成,用于与航天贮箱的上支撑裙和航天器的承力筒连接;下端固定结构包括活动轨道、下安装环、弹簧组以及挡板,用于与航天贮箱的下支撑裙和航天器的承力筒连接;活动轨道与挡板焊接固定,下安装环套设在活动轨道与挡板之间,弹簧组套设在下安装环与挡板之间。本申请满足了双支撑裙航天贮箱柔性安装的需求,大幅降低了航天贮箱工作过程轴向膨胀和收缩引起的贮箱变形和应力的集中,保障了发射和运行力学环境下双支撑裙航天贮箱安装结构的可靠性。
