Configuration of satellite loaded with large deployable antenna with double reflecting surfaces

Abstract

The invention provides configuration of a satellite loaded with a large deployable antenna with double reflecting surfaces. The relative position relation of a feed source array, a main reflecting surface and an auxiliary reflecting surface in an in-orbit flight state is guaranteed, main force transfer path design is optimized through design of a payload capsule in a truss structure style and reasonable layout and placement while the constraint conditions about enveloping of a fairing of a carrier rocket and correct deployment of the large deployable antenna are met, compactness and reasonableness of structure space of the large deployable antenna in a folded state can be guaranteed, meanwhile, the deploy path requirement of the large deployable antenna is met, and the area of a satellite solar cell array is guaranteed by fully using the enveloping space provided by the carrier rocket.

Description

technical field [0001] The invention relates to the field of satellite technology in aerospace technology, in particular to a satellite configuration equipped with a large-scale deployable antenna with double reflectors. Background technique [0002] According to the configuration design experience of existing satellites, such as optical satellite cameras, electronic reconnaissance satellite antennas, and communication satellite large-scale reflector antennas are directly installed on the satellite platform as satellite payload components to maintain their working conditions. On-orbit flight is basically the same as on the ground, but the configuration design technology of satellites with large deployable antennas is quite different. Due to the large size of the large deployable antenna, which is far beyond the allowable range of the envelope of the launch vehicle's fairing, it needs to be folded within the allowable envelope of the launch vehicle's fairing through configura...

Problems solved by technology

[0004] As a big aerospace country, my country's satellite industry is in a period of vigorous development, and the demand for satellites that can be loaded with large-caliber and large-scale deployable antennas is becoming more and more urgent. However, due to the constraints of the launch vehicle fairing, loading a large-scale deployable There are strict restrictions on the envelope size and so on. The above factors have put forward strict restrictions on the layout design of the satellite configuration of the large-scale deployable antenna equipped with double reflectors.
