Axial sliding type partition plate suitable for multi-pulse solid rocket engine

Abstract

The invention discloses an axial sliding type partition plate suitable for a multi-pulse solid rocket engine, and belongs to the technical field of multi-pulse solid engines. The axial sliding type partition plate suitable for the multi-pulse solid rocket engine is mainly composed of a partition plate and a sealing ring. According to the axial sliding type partition plate suitable for the multi-pulse solid rocket engine, a combustion chamber of a solid rocket engine is divided into a plurality of parts through the axial sliding type partition plates, the axial sliding type partition plates slide towards the rear section of the engine, the rear section of the engine charges bear the pressure generated when the front section of the engine works, and the situation that the partition plates are broken, and consequently the rear section of the engine charges are ignited is avoided; besides, one-way breaking is achieved through prefabricating defects of the axial sliding type partition plate, normal work of the rear section of the engine is guaranteed, that is, multiple times of shutdown and starting of the multi-pulse solid rocket engine are achieved through the axial sliding type partition plate with prefabricating defects, thrust and pulse interval time are reasonably distributed, and optimal management of engine energy is achieved. The axial sliding type partition plate suitable for the multi-pulse solid rocket engine has the advantages of being suitable for complex medicine types, low in cost, light in weight, simple in structure and convenient to install.

Description

technical field [0001] The invention relates to an isolation device suitable for multi-pulse solid rocket motors, belonging to the technical field of multi-pulse solid rocket motors. Background technique [0002] The traditional solid rocket motor works after one ignition and burns to the end. It can only provide one thrust and has poor maneuverability at the end of the trajectory. The multi-pulse rocket engine can manage the energy of the engine reasonably and effectively. Compared with conventional rocket engines, it has the advantages of long range, high terminal guidance speed, and good maneuverability. [0003] A multi-pulse engine utilizes an isolator to achieve multiple ignitions, thereby enabling multi-pulse operation. As the core component of the pulse engine, the isolation device divides the engine combustion chamber into multiple propellant units, which can realize multiple ignitions, enable the transmitter to be shut down and started multiple times, reasonably d...
