Partition plate cone body forming method for soft partition plate for double-pulse engine

Abstract

The invention discloses a partition plate cone body forming method for a soft partition plate for a double-pulse engine. A parting surface section is embedded into the cone section end portion of a partition plate cone body. According to the forming method, inner EPDM is placed into a pressing die to be subjected to pre-sulfurization, so that inner layer pre-EPDM is formed; the inner layer pre-EPDM is placed into the pressing die, and an inner enhancement material layer, middle layer EPDM, an outer enhancement material layer and outer layer EPDM are sequentially laid on the inner layer pre-EPDM from inside to outside, so that an overall preformed part is formed; and an embedding part of the pressing die is filled with EPDM and then loaded into the pressing die, and room-temperature cold pressing and sulfidation mold releasing are carried out to form the partition plate cone body with the parting surface section. According to the method, the technology can ensure the appearance structure size and the inner quality requirement of the partition plate cone body, strength of all adhesion interfaces meets the design objective requirement, the air tight performance obtained after fiber winds around a shell can be ensured, it is ensured that when double-pulse opening is carried out, connection with the engine shell is firm and overall falling is avoided, and ablation performance duringengine run is ensured.

Description

technical field [0001] The invention belongs to the field of making soft partitions for double-pulse engines, in particular to a partition cone forming method for soft partitions for double-pulse engines. Background technique [0002] The double-pulse motor is a new technology in the field of solid rocket motors. It separates the motor into two relatively independent combustion chambers through a soft partition, and the two combustion chambers work continuously or at intervals, which can effectively realize the control and distribution of engine energy. . The soft partition plays the following roles in the dual-pulse engine casing: [0003] 1. The heat insulation and heat insulation effect of conventional engine heat insulation layer; [0004] 2. When the one-pulse engine is working, the soft partition plays the role of bearing the internal pressure of the engine; [0005] 3. During the working interval of the first and second pulse engines, the soft partition is required...

AI Technical Summary

Problems solved by technology

When the product is opened, the soft partition does not allow large fragments to fly out, let alone fly out as a whole, so as not to block the engine nozzle, which will cause the internal pressure of the engine to rise sharply beyond the engine burst pressure value and cause the engine to explode.
