Problems solved by technology

From the perspective of aerospace economy, the economic benefits of the fairing are relatively low
The fairing not only consumes a lot of fuel during the launch process, but more importantly, the fairing greatly restricts the freedom of various spacecraft structural designs, and becomes an insurmountable barrier for large-scale and new spacecraft structural designs

Abstract

The invention provides a fairing-main satellite integrated large-caliber deployable spacecraft. The fairing-main satellite integrated large-caliber deployable spacecraft comprises a spacecraft main satellite and the like, wherein the spacecraft main satellite is connected with a fairing through a deploying mechanism; the fairing is connected with a flexible cable net; a plurality of fairing top covers are connected with the deploying mechanism, and are connected with the fairing through hinges; the flexible cable net is used for being connected with the fairing, and a large-caliber antenna isformed by the flexible cable net and the fairing; in a launching process, the fairing is furled to achieve the effect of rectification; in the launching process of the spacecraft, the fairing top covers achieve the effect of rectification; after being in an orbit, the fairing is deployed under the driving of the deploying mechanism; and the deploying mechanism is used for being connected with thefairing and the spacecraft main satellite and driving the fairing to be deployed. According to the fairing-main satellite integrated large-caliber deployable spacecraft disclosed by the invention, a large-caliber satellite-mounted antenna design is realized, the limit to the large-caliber satellite-mounted antenna is removed, and the formset surface error of the large-caliber satellite-mounted antenna is effectively controlled.

Description

technical field [0001] The invention relates to a spacecraft, in particular to a large-diameter deployable spacecraft with a fairing main star integrated. Background technique [0002] The satellite antenna refers to the antenna loaded on the artificial satellite. It is the input and output device of the satellite signal. The satellite communication is realized through the mutual transmission of electromagnetic waves between the satellite antenna and the earth station antenna. With the rapid development of my country's space technology, such as communication satellite technology, relay satellite and earth observation technology, the demand for spaceborne antennas is increasing day by day, and the requirements for its caliber and precision technical indicators are also getting higher and higher. However, at this stage, the functions and overall layout of any satellite are limited by the envelope space of the launch vehicle. The limited space of the fairing forces the develop...
