Its function is to connect the various subsystems on the rocket, such as payload, control system, power system and measurement system, into a whole, provide them with a reliable working environment, withstand external forces during ground operations and flight, maintain a good aerodynamic shape, and maintain the integrity of the rocket.

[0003] The rocket body structure is the assembly of supporting components that bear various loads. Like a human body, it connects the rocket's payload, flight control system, and propulsion system into a complete whole, forming a streamlined and smooth outer shell that protects the instruments and equipment inside the rocket body. Therefore, people commonly call it the rocket shell.

[0004] When using the trawl structure compartment in the rocket body structure for testing, the traditional rocket body structure trawl structure compartment is only made of better materials. During use, due to the high degree of burning materials, the temperature inside the body will rise sharply, making the trawl structure compartment dangerous, burning and deforming, and even exploding, thereby increasing the risk factor of the device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rocket-propelled trawl structure bin, including a pusher, the bottom of the pusher is fixedly connected to a connecting plate near the center by fixing bolts, the bottom of the connecting plate is fixedly installed with a combustion bin, the outer surface of the combustion bin is fixedly connected with a plurality of buffer rods equidistantly along the circumferential direction, a protective sleeve is fixedly connected between one ends of the plurality of buffer rods, the outer surfaces of the plurality of buffer rods are fixedly sleeved with a buffer spring, one end of the buffer spring is welded to the outer surface of the combustion bin, and the other end of the buffer spring is welded to the inner surface wall of the protective sleeve, and the bottom of the combustion bin is fixedly connected with a tail bin.

[0007] As a preferred embodiment, a jet port is provided near the center of the bottom of the tail bin.

[0008] As a preferred embodiment, a fixing hoop is fixedly sleeved at the edge of the outer surface of the tail bin near the top, and a protective trawl net cover is fixedly connected to the bottom of the fixing hoop along the circumferential direction, and the protective trawl net cover and the tail bin are in a wrapped state.

[0009] As a preferred embodiment, the outer shell of the combustion chamber includes a flame retardant layer, and a high temperature resistant layer is fixedly provided on the outer surface of the flame retardant layer.

[0010] As a preferred implementation, a breathable layer is fixedly connected to the outer surface of the high temperature resistant layer.

[0011] As a preferred implementation, an explosion-proof layer is fixedly provided on the outer surface of the air-permeable layer.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the thruster is installed on the rocket structure, and then high combustion is carried out inside the combustion chamber, so that the tail chamber sprays exhaust gas, thereby generating a reaction force to push the rocket. During the combustion process, the combustion chamber is supported by the buffer rod, so as to prevent the combustion chamber from being deformed by high temperature, and the supporting force of the buffer rod can be slowed down under the action of the buffer spring, so that the device is convenient for effective support. The combustion chamber is protected by the protective cover, so that it can play a good protective role and prevent part of the structure from affecting the use of the rocket, so that the rocket is convenient for effective use and the safety of the device is improved.

During the exhaust gas spraying process, the tail bin is fixed by the fixing hoop, and the tail bin is protected by the protective trawl cover, so that the tail bin can be better protected when in use. Furthermore, by setting the flame retardant layer, the interior of the combustion bin can be prevented from burning, the high temperature resistant layer can protect the external structure to prevent high temperature from affecting the external structure, the breathable layer can remove water vapor to prevent internal energy accumulation, and finally the explosion-proof layer makes the device easy to be explosion-proof and can be better used, thereby reducing the danger of the device.
