Abstract

The invention discloses a sandwich-structure all-composite-material launching canister, and relates to an all-composite-material launching canister which is of a sandwich structure. The invention aims at providing a sandwich-structure all-composite-material launching canister which is high in load-bearing efficiency and light in weight. The sandwich-structure all-composite-material launching canister which is provided by the invention comprises a canister section (1) and a primary holding chamber (2), wherein the primary holding chamber is fixedly connected with the canister section; the canister section comprises an inner canister (11), and outer canister (13) and a foam sandwich (12); the foam sandwich is located between the inner canister and the outer canister; both the inner canister and the outer canister are made from fibrous pre-impregnated materials; and the thickness ratio of the inner canister to the outer canister is 1.2 to 1.4.

Description

technical field [0001] The invention relates to a launch tube, in particular to a launch tube with a sandwich structure and an all-composite material. Background technique [0002] The launch tube is an important part of the missile weapon system. In order to improve the mobility of missile weapon systems, the launch tubes of various domestic weapon models show a trend of composite materials. The existing composite material launching tube has low loading efficiency and heavy weight. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sandwich-structure full-composite launching tube with high load-carrying efficiency and light weight. [0004] The full-composite launching tube with a sandwich structure of the present invention comprises a tube section and an initial chamber fixedly connected with the tube section, the tube section includes an inner tube, an outer tube and a foam interlayer, and the foam interlayer...
