Abstract

The invention provides a propellant storage tank skirt mounting structure and a manufacturing method thereof. The propellant storage tank skirt mounting structure comprise a metal liner (1), a first composite layer (2) wound around the metal liner (1), a second composite layer (3) wound around the first composite layer (2), epoxy resin glue (4) spayed onto the second composite layer (3), a storage tank skirt (5) being in glue joint with the epoxy resin glue (4), and a third composite layer (6) wound around the storage tank skirt (5). According to the propellant storage tank skirt mounting structure, a storage tank is mounted on a final assembly structure through the storage tank skirt; the storage tank skirt (5) is made of an aluminum alloy or a composite and fixed on a storage tank shell in a glue-joint or winding manner; and accordingly, the propellant storage tank skirt mounting structure is capable of bearing the axial overload, the transverse overload and other mechanical environments. By adoption of the propellant storage tank skirt mounting structure, the problem that a conventional large-volume composite-wound storage tank shell mounting structure is difficult to design and manufacture, low in mechanical environment resistance, and the like can be solved, as well as the whole structure efficiency of the storage tank and the mechanical environment applicability can be improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular, the invention relates to a propellant storage tank skirt installation structure and a manufacturing method thereof. Background technique [0002] With the development of aerospace technology, the propulsion system has higher and higher requirements for the lightweight design of the propellant tank. Compared with traditional metal material storage tanks, composite material winding storage tanks have many advantages such as light weight, high reliability, and failure mode safety. More than 500 liters of composite material winding storage tanks developed in China have been successfully applied to propulsion systems, but Due to the limitation of the winding structure of the shell, the installation method of the more than 500-liter composite material winding storage tank is the installation method of the lower end flange and the upper end tie rod. This installation method has high re...
