Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 and 2 Shown, a kind of small-sized solid rocket motor nozzle capping, described capping 3 is provided with capping connecting thread 4, and nozzle capping is connected with nozzle shell side wall by capping connecting thread 4, described The nozzle cap is provided with a shear groove, and the shear groove is arranged on the contact surface between the plug and the nozzle. The connecting thread 4 of the plug is connected with the side wall of the nozzle through the sealing ring 2 . During specific implementation, the dimensions of the shear groove 5 and the connecting thread 4, 7 are calculated according to the opening pressure requirement of the nozzle plug. The side seal compression of sealing ring 2 is selected as 15%. When the nozzle cap of the present invention is used, the seal ring 2 is installed in t...

Abstract

The invention relates to a jet pipe blocking cover, in particular to a small solid rocket engine jet pipe blocking cover. The jet pipe blocking cover is provided with a blocking cover connecting thread and a shearing groove. The jet pipe blocking cover is connected with the side wall of a jet pipe shell through the blocking cover connecting thread, and the shearing groove is formed in the face, incontact with the jet pipe, of the blocking cover. According to the small solid rocket engine jet pipe blocking cover, reliable connection of the blocking cover can be achieved, working reliability ofa solid rocket engine is improved, and the small solid rocket engine jet pipe blocking cover is suitable for most small solid rocket engines.

Description

technical field [0001] The invention relates to a nozzle plug, in particular to a small solid rocket motor plug. Background technique [0002] The nozzle cap is one of the key components of the solid rocket motor, and its main function has two aspects: one is to seal against moisture, prevent outside air from entering the combustion chamber, and affect the storage life of the solid rocket motor; the other is to provide an instantaneous airtight container when the engine is ignited , so that the gas stays in the combustion chamber for a period of time, helps the engine build up pressure quickly, shortens the ignition delay time, and achieves reliable ignition. The existing nozzle cap is fixed on other parts of the nozzle by bonding or welding. The bonding method is affected by factors such as bonding surface treatment, specific bonding process, and curing conditions. The connection part is partially debonded, and air leakage occurs. The welding method is suitable for the s...
