Problems solved by technology

However, the thermal expansion coefficient of the metal flange does not match the thermal expansion coefficient of the composite material. No matter how the metal flange and the composite material structure are connected under the environment of temperature changes, cracks will appear at the connection between the metal flange and the composite material structure, which is difficult. Ensure that the box structure has good airtightness

Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Composite box body structure of the present invention such asfigure 1 As shown, the box is surrounded by the four-sided base plate 1 of the box body, and transverse reinforcing ribs 2 are arranged at equal intervals along the length direction of the four-sided base plate 1 of the box body. The layers 11 form a whole full-composite flanging flange 3, and there is a reinforcing transition layer 4 between the full-composite flanging flange 3 and the thickened layer 11 at the end of the box substrate.

[0038] The box base plate 1 of the present invention is taken as R=R by taking the shallow arched shell plate 5 and the four corners of the box body that the four sides arch height of the box body is f O The cylindrical shell plate consists of 6 smooth connections, such as figure 2 As shown, one side of the four-sided subs...

Abstract

The composite material box body structure for storage and transportion box of missile is characterized by that said box body structure possesses the shallow arched single shell plate structure with longitudinal reinforcement member and transverse reinforcing rib and correspondent symmetrical layer-spread form, its four-side base plate of said box body structure is made up by using four-side small arch degree and shallow arched shell plate and four-corner cylindrical shell plate which are smoothly connected togher, along the length direction of base plate of box body the transverse reinforcing ribs are uniformly-spaced and placed, two ends of said box body adpots the all-composite material flange flanges which are connected with box body base plates together and formed into one body, so that said box body structure possesses high specific strength.

Description

Technical field: [0001] The invention relates to a composite material box structure of a storage and transportation launch box, which is the main load-bearing structure of the storage and transportation launch box, and is used for supporting and fixing, transporting, airtight and dry storage and vertical heat-launching missiles. Background technique: [0002] The high performance, high reliability and low cost of advanced launch vehicles and missiles largely depend on the application of new materials and the corresponding structural optimization design, which can effectively reduce the structural mass of launch vehicles and missiles, increase the payload and range , Reduce launch costs. The function of the general missile launching box is only used to launch missiles and does not possess the functions of storing and transporting missiles simultaneously. Such a box body structure is cylindrical. In the MX missile finalized by the United States in the late 1980s, the cylindri...
