Problems solved by technology

The disadvantage is that the hard diaphragm needs a certain thickness as a pressure-bearing structure, and the material density is high, and the negative mass is large, so it cannot be used for large-diameter double-pulse engines

Abstract

The invention discloses an integrated dual-pulse solid engine soft interlayer, and relates to the technical field of dual-pulse solid rocket engines. The designed integrated dual-pulse solid engine soft interlayer comprises a cone, a sleeve and a connecting sleeve, and the cone comprises an ethylene propylene diene monomer layer and a carbon cloth layer; the sleeve comprises an ethylene propylenediene monomer layer, a carbon cloth layer and a carbon fiber winding layer; and one end of the connecting sleeve is connected with an ignition device, and the other end of the connecting sleeve is connected with the end, away from the cone, of the sleeve. Pulse isolation of a dual-pulse engine is achieved, integrated forming can be achieved through bonding of the cone and a first-second pulse heat-insulating layer as well as connecting and sealing of the connecting sleeve and the ignition device, an integrated forming technology is simplified through the method, the negative mass can be effectively decreased, and the engine mass ratio is increased.

Description

technical field [0001] The invention relates to the technical field of double-pulse solid rocket motors, in particular to an integrated double-pulse solid rocket motor soft interlayer. Background technique [0002] The integrated dual-pulse solid rocket motor mainly includes two independent grains and their ignition systems, sharing a combustion chamber and nozzle. The combustion chamber is divided into a first-pulse combustion chamber and a second-pulse combustion chamber by the pulse isolation device, and the isolation of the two pulses is realized through the connection of the pulse isolation device with the combustion chamber insulation layer and the ignition device. As a key component of the double-pulse engine, the function of the pulse isolation device is to seal and protect the second pulse grain when the first pulse is working. The two pulses provide gas flow channels while opening the product without affecting the normal operation of the engine. [0003] The exis...
