Abstract

The invention relates to the technical field of composite gas cylinders, in particular to a winding type flange base and a manufacturing method thereof. The winding type flange base comprises a barrel section winding area, a stress reinforcing area, an seal head gradual change wall thickness area, a base mounting area and a base restraining area which are sequentially connected; the barrel section winding area is wound and fixed with the outer layer of a composite layer of a barrel section of a composite gas cylinder; and the wall thickness of the stress reinforcing area is larger than two times of the basic wall thickness. Uniform lightening holes are formed in the seal head gradual change wall thickness area; uniform threaded holes are formed in the base mounting area in the circumferential direction; and the base restraining area is matched and connected with a wire hanging table of the composite gas cylinder. The winding type flange base provided by the invention has the characteristics of light weight, high strength, high dynamic load resistance, high reliability and high safety, and is mainly used for fixing and winding the composite gas cylinder, so that the composite gas cylinder which is large in volume, heavy in weight, high in length-diameter ratio, light in weight and high in strength and carries an overweight working medium can be perfectly assembled and butted with a novel truss type bearing structure of a satellite.

Description

technical field [0001] The present application relates to the technical field of composite material gas cylinders, in particular to a wound flange base and a manufacturing method thereof. Background technique [0002] The truss-type load-bearing structure has the advantages of light weight, high strength, high structural efficiency, high space efficiency, and high natural frequency, and has become the first choice for the load-bearing structure of new large satellite platforms. The new large-scale satellite platform adopts a truss-type load-bearing structure to replace the traditional load-bearing cylinder-type load-bearing structure. The electric propulsion subsystem of the satellite platform needs to carry a larger amount of high-pressure xenon propellant for 10-15 years and a longer service life. Therefore, the composite gas The bottle structure is developing in the direction of large volume, large weight, high aspect ratio, light weight and high strength. The weight of t...
