Abstract

The invention provides a combustion chamber cylinder section-seal head heat insulation layer integrated extrusion molding system and method. The combustion chamber cylinder section-seal head heat insulation layer integrated extrusion molding system comprises a base, an extruder and a combustion chamber shell, and the combustion chamber shell is of a cylinder section-seal head integral structure, and the system further comprises a transition sleeve, a core mold, a core mold adapter flange and a support, wherein the extruder, the transition sleeve, the core mold, the combustion chamber shell, the core mold adapter flange and the support are coaxially arranged in sequence from left to right; the method specifically comprises the following steps of 1, a preparation stage; 2, a mold-shell buttjoint stage; 3, an extrusion molding stage; and 4, a dismounting and post-processing stage. Based on the mature process of extrusion in the civil field, the integrated rapid molding function of the cylinder section-seal head heat insulation layer is achieved, meanwhile, the cost of equipment, the process, a mold and the like can be greatly reduced, and meanwhile the application range of a heat insulation sizing material system is very wide.

Description

technical field [0001] The invention belongs to the field of solid rockets and relates to the manufacture of an engine heat insulation layer, in particular to an extrusion molding system and method for an integrated extrusion molding of a combustion chamber section-head heat insulation layer. Background technique [0002] With the development of high performance and low cost of solid rocket motor or ramjet motor, corresponding requirements are put forward for the thermal protection structure of the motor. As the main thermal protection structure of the combustion chamber, the heat insulation layer has an important impact on the ablation resistance and quality reliability of the engine, and the manufacturing process of the heat insulation layer is one of the important factors that determine its quality reliability. [0003] The solid rocket or ramjet combustion chamber is similar to a high-pressure vessel structure, which is usually composed of a thin-walled tube body and an ...
