Abstract

The invention relates to a plate-type satellite structure for parallel launching of a rocket and multiple satellites and an assembling method. The plate-type satellite structure for parallel launchingof the rocket and the multiple satellites comprises a satellite main structure and a separation structure assembly. The interior of the satellite main structure is used for fixing satellite load equipment and satellite platform equipment, and the outer wall of the satellite main structure is used for fixing a satellite antenna and a solar wing. The separation structure assembly is used for reinforcing the satellite main structure and fixing the satellite main structure to the outer side of a satellite distributor, the satellites can be separated from a carrier rocket independently or the satellites can be separated from the carrier rocket simultaneously through the satellite distributor, the space in the height direction of a fairing is fully utilized, the manufacturing cost is low, the manufacturing period is short, and the assembling is simple and convenient.

Description

technical field

[0001] The invention relates to a plate frame satellite structure and an assembly method for multi-satellite parallel launching of one rocket, and belongs to the overall technical field of aerospace. Background technique

[0002] With the expansion of satellite application requirements, the demand for small and medium-sized satellites with simple structure, low development cost, short manufacturing cycle, and multiple satellite launches with one arrow is increasing year by year, and they are gradually entering mainstream application fields such as communication, remote sensing, science, and deep space exploration.

[0003] The multi-satellite launches of the existing one-ton satellites in our country all carry layered fairings specially made for them. They are connected to the carrier brackets through the connecting flanges at the bottom of the satellites. The rectifications are discarded in sequence from top to bottom. The cover, the satellite and the rocket...

Embodiment Construction

[0047] The purpose of the present invention is to design a satellite structure under the premise of making full use of the space of the column section of the fairing, and adopt a structure in which the satellite is connected to the support of the launch vehicle through the connection point on the side wall, so as to realize the double star or multiple satellites in parallel For launch tasks, the structure of the present invention can simultaneously bear shear and axial force during rocket launch and the separation process of the satellite and the launch vehicle.

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] Such as figure 1 Said, a kind of board frame satellite structure used for multi-satellite parallel launching of one rocket includes: satellite main structure and separate structural components;

[0050] The interior of the satellite main structure is used to fix satellite load equipment and ...
