High-rigidity light launching box

Abstract

The invention discloses a high-rigidity light launching box and relates to a launching box used for supporting, fixing, transporting and storing missiles. The high-rigidity light launching box is high in both circumferential rigidity and longitudinal rigidity and light and can provide large storage space for the missiles, and the stress on the corners of the launching box can be effectively diffused. The high-rigidity light launching box comprises an outer skin, an inner skin, longitudinal ribs and ring ribs evenly distributed between the outer skin and the inner skin. The ring ribs are connected with the outer skin and the inner skin through glue respectively, the ring ribs are installed on the inner skin in a sleeved mode, small rounded corners are adopted for the corners of the inner skin, the outer skin and the ring ribs, the space between the inner skin and the ring ribs is filled with a heat preserving layer, reinforcing blocks are arranged on the corners of the heat preserving layer, filling interfaces are arranged on the longitudinal ribs, a 35-degree laying layer is adopted for the inner skin, the longitudinal rib laying layers and the ring rib laying layers respectively comprise 0-degree laying layers and 90-degree laying layers, the proportion of the laying layers of the longitudinal ribs is as follows: n 0 degree: n 90 degrees= 2:1- 3:1, and the proportion of the laying layers of the ring ribs is as follows: n 90 degrees: n 0 degree= 2:1- 3:1.

Description

Technical field [0001] The invention relates to a launching device, in particular to a launching box for supporting, fixing, transporting and storing missiles. Background technique [0002] The launching device plays an important role in the precise launch of the missile. Traditional missile launches are launched using a launch tube, but the storage volume of the launch tube is usually relatively small, and the loading interface of the launch tube is relatively simple and regular. With the continuous range of the missile In order to be able to adapt to the increasing volume of missiles, the structural quality of the launch device is significantly reduced, and the launch box structure suitable for mass production has become a development trend. [0003] For the traditional launch box, as the volume of the missile continues to increase, the size of the section of the launch box and the internal pressure in the launch box also increase. When the missile is launched in the launch box, ...

[0002] The launch device plays a very important role in the precise launch of missiles. Traditional missiles are launched using a launch tube, but the storage volume of the launch tube is usually relatively small, and the loading interface of the launch tube is relatively simple and regular. As the range of missiles continues to increase In order to adapt to the increasing volume of missiles, the structural quality of the launching device is significantly reduced, and the launch box structure suitable for mass production has become a development trend.

[0003] For the traditional launch box, as the volume of the missile continues to increase, the cross-sectional size of the launch box and the internal pressure in the launch box also increase. When the missile is launched in the launch box, stress concentration occurs at the corner of the section of the launch box, and In order to avoid large stress concentration in the traditional launch box, the corners of the box section are often designed with large rounded corners, but this design form of large rounded corners reduces the safety gap between the missile and the launch box, and at the same time reduces the storage space for the missile; the traditional launch box The layering form of the inner skin of the box is usually the layering design form of 0°, 90° and 45°. The launch box with this type of layering on the inner skin is not conducive to optimizing the safety factor of the structure, and is not conducive to the launch and transportation of missiles. and storage; and the box body of the traditional launching box adopts solid ribs, which makes the structure of the box body heavier, which is not conducive to improving the weight ratio of the bomb box and the mobility performance. The traditional ring ribs and longitudinal ribs are not fixed. The structural form of the longitudinal reinforcement of the ring reinforcement is determined, so the traditional laying of the ring reinforcement and longitudinal reinforcement is not optimized, and cannot provide the maximum hoop and longitudinal stiffness; and the hoop stiffness and longitudinal stiffness of the entire box are not optimized enough, both It has a certain restrictive effect on the launch and transportation of missiles
