Force-bearing integrated structure with honeycomb-sandwich storage boxes

Abstract

The invention discloses a force-bearing integrated structure with honeycomb-sandwich storage boxes. The force-bearing integrated structure comprises a plurality of storage boxes connected mutually, wherein the storage boxes are uniformly paved along the circumference; adjacent storage boxes are mutually embedded, flanges are connected by the storage boxes, and clamping blocks and wrapping belts are mutually connected; the load acting positions of the top part and the bottom part of each storage box are respectively provided with a claw-shaped force-transferring structure in an embedded manner; and the claw-shaped force-transferring structures are respectively connected with upper flanges and lower flanges. Different from the traditional satellite design that the actions of structure subsystems and propelling subsystems are completely separated and independent, main force-bearing structures of the structure subsystems and the storage boxes of the propelling subsystems are shared by the force-bearing integrated structure with the storage boxes, so that a spacecraft has compacter appearance and distribution, and further the mass of the structure subsystems and the mass of the propelling subsystems are reduced.

Description

technical field [0001] The invention relates to a spacecraft used in the technical field of high-orbit large platforms, in particular to a honeycomb interlayer tank load-bearing integrated structure applied to high-orbit large platforms. Background technique [0002] At present, the existing high-orbit satellite platforms in China adopt independent design methods. The long-distance orbit-changing propulsion system and the structural system are separated from each other, and the functional components do not overlap with each other, which brings great obstacles to the weight reduction of the platform. The orbit change module is fixedly connected with the main mission module. After the fixed-point orbit is completed, the residual propellant in the large-volume storage tank is less than 5%, but the large-scale storage tank will still accompany the entire life cycle of the satellite and become a redundant burden. The structure technology of the tank-bearing propulsion module is a...

The orbit change module is fixedly connected with the main mission module. After the fixed-point orbit is completed, the residual volume of propellant in the large-volume storage tank is less than 5%, but the large-scale storage tank will still accompany the entire life cycle of the satellite and become a redundant burden.
