Embodiment Construction

[0015] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the automatic reset launcher back cover of the present invention is composed of a detachable back cover, a rebound mechanism and a guide structure. The rebound mechanism includes an upper mounting seat 1, a lower mounting seat 2, a high temperature spring 3, and a buffer pad 4 , mandrel 5. The upper mounting base 1 is installed on the detachable back cover 8 of the launch box through bolts, the mandrel 5 is located in the middle below the upper mounting base 1, the lower connecting base 2 is installed on the guide base of the launch box, and the high-temperature spring 3 is set on the mandrel 5, and constrained by the cooperation between the mandrel 5 and the shaft hole of the lower m...

Abstract

The invention relates to an automatically returned launching cylinder rear cover and relates to the technical field of launching. The automatically returned reflection cylinder rear cover consists ofa separable rear cover, a spring-back mechanism and a guide structure, wherein a launching tank rear cover spring-back mechanism is matched with the spring-back mechanism, a rear cover flange and theseparable rear cover, and spring-back of the launching tank rear cover is achieved; in the launching process of an aircraft, a high-temperature spring of the spring-back mechanism is compressed by theseparable rear cover under the action of combustion gas pressure of a booster, then the rear cover can be rapidly, reliably and safely opened, and combustion gas flow discharge and guidance are achieved; after the aircraft is launched outside a box, the combustion gas is eliminated, the separable rear cover is sprung back under the action of the spring, and thus the closed state of the rear coveris recovered.

Description

technical field [0001] The invention relates to the technical field of launching, in particular to an automatically resettable back cover of a launching tube. Background technique [0002] In the traditional detachable back cover solution, the back cover cannot be restored to the closed state after opening. In a launching device with multiple bombs sharing a self-discharging channel, after the aircraft is launched, if the rear cover cannot be closed, the gas in the adjacent position will ablate the launched position; and the launched position will become The gas discharge channel will change the trajectory inside the barrel of the aircraft with different launch numbers due to the increase of the discharge area. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to design an automatic resettable rear cover of the launching tube that meets the needs of a launching device with m...
