Problems solved by technology

[0004] Due to the small size of the current xenon gas storage tank, the installation structure generally adopts a strap connection, and the inner surface of the storage tank cannot be polished, and the purity of the xenon gas in the storage tank can only be improved through repeated replacement, resulting in a large amount of expensive xenon gas waste.

Abstract

The invention provides a spacecraft composite material storage box. The storage box is characterized by comprising a metal lining 1, a bonding layer 2, a fiber winding layer 3, an installation platform 4, a skirt cementation layer 5, a skirt flange 6 and a flange composite winding layer 7, the bonding layer 2 is smeared and bonded on the outer surface of the metal lining 1, the fiber winding layer 3 is wound on the outer surface of the bonding layer 2, the installation platform 4 is wound on the outer surface of the fiber winding layer 3, the skirt cementing layer 5 is arranged between the outer surface of the installation platform 4 and the inner surface of the skirt flange 6, after the skirt flange 6 is cemented, a locking pin 8 is inserted between the installation platform 4 and the skirt flange 6 for locking, and the flange composite winding layer 7 is wound on the outer surface of the skirt flange 6.

Description

technical field [0001] The invention relates to the technical field of spacecraft composite material pressure vessels, in particular to a composite material xenon storage tank for spacecraft and a manufacturing method thereof. Background technique [0002] With the development of aerospace technology, the demand for the application of electric propulsion systems with higher specific impulse advantages is becoming more and more urgent. All-electric propulsion satellite platform with chemical propulsion engine. [0003] The most commonly used working medium for electric propulsion systems is xenon gas, which is a high-density inert gas whose density has exceeded that of liquid chemical propellants. At the same time, in order to improve the working life of electric thrusters, the purity of xenon gas in storage containers is required Reaching more than 99.9995%, these have put forward special requirements for xenon gas storage containers that are different from conventional gas...
