Embodiment Construction

[0033] This embodiment is a model drone rocket booth, including thrust rod 1, front top cover 2, combustion chamber 3, nozzle, screw 5, igniter 6, and clogging 7. Wherein, the front top cover 2 is located at the front end of the combustion chamber 3; the center positioning sleeve 8 of the pushing rod is set on the positioning boss at the center of the front top cover, and the end surface of the front end cover and the thrust rod. The end face of the flange plate. The igniter 6 is located within a chamber formed between the front end surface of the front top cover and the front end surface of the combustion chamber, and one end of the igniter is located in the threaded blind hole of the inner end surface of the front cover; the ignition The server 6 is the prior art. The nozzle 4 and the clogging 7 are all prior art and assembled according to conventional methods, and the segments of the nozzle are mounted in the rear end of the combustion chamber by thread; blockage 7 is mounted i...

Abstract

The invention discloses an unmanned aerial vehicle rocket booster. An ellipsoidal front top cover is located at the front end of a combustion chamber; and a central positioning sleeve of a thrust rodis sleeved on a positioning boss at the center of a front top cover, and the end surface of the front end cover is attached to the end surface of a thrust rod flange plate. A convergent section of a nozzle is mounted at the rear end of the combustion chamber; a plug is installed in the nozzle and located in the expansion section of the nozzle. The head of the top cover is the ellipsoidal surface,under the same working internal pressure and the same safety coefficient, the stress condition of the ellipsoidal surface is better, the wall thickness of the shell is lower, and the mass of the top cover can be effectively reduced. The sealing performance of the connecting part is improved, and the assembling precision of the connecting part is improved through a guide section; by improving a booster top cover and a booster thrust rod, the assembly difficulty of the top cover and the thrust rod is reduced, the connection stress condition of the thrust rod and the combustion chamber top coveris improved, and the thrust deflection numerical value of the booster is reduced.

Description

Technical field [0001] The present invention relates to the technical field of solid rocket engines, and is specifically a drone rocket booth. Background technique [0002] In recent years, the drone market has vast, drone models and related design technologies, and the corresponding matching parts are also outlined. The booster is an active source of the drone, and its important position is unable to shake. With the continuous development of drone design technology, the overall performance indicators of the booster also put forward new requirements. [0003] Solid rocket engines As a booster, several indicators are thrust skew, average thrust, and working hours. One of the important factors affecting the skewing of the thrust is the selection and design of the connection. Typically, the drone rocket booth is connected to the drone through the thrust rod. The existing drone booth and thrust rods are used in the form of threaded connection, that is, the booster top cover and the t...
