Abstract

The invention discloses a spaceflight power bus which is characterized by comprising aluminum alloy conductors, a spaceflight special adhesive and polyimide adhesive tapes, wherein the aluminum ally conductors consist of an inner conductor 1 and an outer conductor 2; colloid 3 is arranged between the inner conductor 1 and the outer conductor 2; a polyimide adhesive tape A 4 is adhered to the surface of the inner conductor 1; a polyimide adhesive tape B 5 is adhered to the surface of the outer conductor. The spaceflight power bus has the advantages that relevant properties, namely, small vacuum outgassing, large current, radiation resistance, U-shaped structure and small weight, of a product in a special environment are improved, the requirements of special application environments with high / low temperature circulation in a spaceflight vacuum environment are met, and the reasonability and the reliability of the design are verified through practical sample experiments. A product is applicable to special environments such as spaceflight vacuum and small space, has excellent mechanical properties and electric properties, and is applicable to special environments of high / low temperature circulation, large current conduction, thermal resistance vacuum outgassing, radiation resistance, atomic oxygen and the like under spaceflight vacuum conditions.

Description

technical field [0001] The invention relates to an aerospace power bus, which can adapt to the special environment of aerospace vacuum, high and low temperature cycle, and narrow space, has excellent mechanical and electrical properties, and can be used for a long time within the range of -50 to +200°C. Background technique [0002] Existing products cannot be used in special environments because they have large vacuum outgassing, low current, are not resistant to radiation, and are heavy. Contents of the invention [0003] The present invention proposes a manufacturing method for an aerospace power bus. Its purpose is to overcome the defect that existing products cannot be used in special environments, meet the special requirements of users in various use environments, and be safe in special environments. , Reliable use. [0004] Technical solution of the present invention: aerospace power bus, its structure includes aluminum alloy conductor, aerospace special glue, poly...
