Abstract

An embodiment of the present invention provides a method for manufacturing a fairing. The method includes: using a first composite material to form a fairing body; using a second composite material to form a cowl; combining the second composite material with the first The materials are different; the fairing body and the cowl are assembled together to form a fairing. In the solution of the present invention, the fairing adopts the separate molding of the fairing body and the hood, which effectively releases the internal stress of the molding, optimizes the outer dimensions of the fairing, and improves its overall assembly accuracy.

Description

technical field [0001] The invention relates to the technical field of fairing manufacture, in particular to a method for manufacturing a fairing. 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 al...
