Embodiment Construction
[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Please refer to the accompanying drawings and describe the present invention in detail below in conjunction with the embodiments. The accompanying drawings are only for reference and description, and do not constitute a limitation to the patent protection scope of the present invention.
[0024] In order to solve the shortcomings of the current launching tube materials, which are more sensitive to the stress concentration of the opening and greatly weaken the structural strength, the invention provides a launching tube opening reinforcement structure.
[0025] The opening reinforcement structure of the launch tube includes: an overall reinforcement structure and a local reinforcement structure. The overall reinforcement structure is located at the opening position of the launch tube body, surrounds the surfac...

The invention discloses a reinforcing structure for a launching tube opening. The reinforcing structure comprises an overall reinforcing structure body and a local reinforcing structure body. The overall reinforcing structure body surrounds the surface of a launching tube body of a launching tube. A through hole is formed in the position covering the launching tube opening. The overall reinforcing structure body is fixedly connected with the surface of the launching tube body. The local reinforcing structure body is located on the periphery of the through hole and fixedly connected with the overall reinforcing structure body. According to the reinforcing structure for the launching tube opening, a light high-intensity combined opening reinforcing structure is achieved, the local reinforcing structure is connected with the launching tube body reliably, and the reinforcing structure is connected with an opening cover or an external device reliably.
Description
technical field [0001] The invention relates to a reinforcing structure, in particular to a reinforcing structure for an opening of a launch tube. Background technique [0002] The launch tube is the key equipment of the cold launch device. It is used to provide a confined space environment, withstand the gas pressure in the tube during launch, provide guidance for the launch object, and provide installation interfaces for various equipment on the tube. [0003] In the context of highly integrated mobile launch platforms, more stringent lightweight requirements are put forward for the launch tube. On the premise of meeting the load-bearing requirements, the launch tube requires its weight to be as small as possible. Therefore, the main material of the launch tube is generally preferred composite material. However, compared with metal materials, composite materials are more sensitive to the stress concentration of openings, which requires that the opening reinforcement has a...
