Abstract

The embodiment of the present invention provides a fairing and a spacecraft, wherein the fairing includes a fairing body and a head cover connected to the fairing body; the fairing body and the head cover are separately formed; and the fairing body and the head cover are made of different materials. In the scheme of the invention, the fairing is formed by separately forming the fairing body and the head cover; the internal stress of the forming is effectively released on the basis of ensuring the overall rigidity, strength, heat resistance and overall light weight of the fairing; and the outerdimensions of the fairing are optimized to improve the overall assembly accuracy.

Description

technical field [0001] The invention relates to the technical field of fairings, in particular to a fairing and an aerospace vehicle. Background technique [0002] The fairing is used to protect satellites and other payloads to prevent satellites from being affected by harmful environments such as aerodynamics, aerodynamic heating, and acoustic vibrations. It is an important part of aerospace vehicles. The fairing is generally a clamshell (two halves) structure, which is composed of a head, a front cone section, a cylinder section, an inverted cone section, and a longitudinal and transverse separation mechanism. According to different missions, each type of launch vehicle has one or more shapes of fairings, such as single star cover, double star cover, multi-star cover, etc. As far as the Long March series of launch vehicles are concerned, there are also satellite fairings for their respective systems. [0003] At present, most fairing molding solutions are aluminum alloy ...
