Abstract

The invention discloses a preparation method of a soft partition plate for a double pulse engine. The method comprises the steps that according to the thickness of a bottom layer of a heat insulation layer of a cylinder section, manual sheet pasting of a heat insulation material is performed on a central spindle; vulcanization forming of the bottom layer of the heat insulation layer is performed by adopting a pressure forming process; carbon fiber cloth dipped with an epoxy resin solution is spread and wound on the surface of the bottom layer of the heat insulation layer; then wet winding and resin solidification of carbon fibers are performed; the preparation of the cylinder section is accomplished; the manual pasting of the bottom layer of the heat insulation layer is performed in a forming mould of a cone section; then the vulcanization forming of the bottom layer of the heat insulation layer is performed by adopting the pressure forming process; the manual pasting and pressure forming of a cover layer of the heat insulation layer are performed; the preparation of the cone section is accomplished; and finally the cylinder section is bonded with the cone section to form the soft partition plate for the double pulse engine. The preparation method is applicable to the forming of the cylinder section and the cone section of the soft partition plate, and composite strengthening layers of both the cylinder section and the cone section are coated with the heat insulation material, so that the overall soft partition plate can bear certain pressure and resist ablation and washing of fuel gas.

Description

technical field [0001] The invention relates to a method for forming a combustion chamber casing of a double-pulse engine, in particular to a method for preparing a soft partition for a double-pulse engine. Background technique [0002] As a major research achievement of the solid rocket motor, the dual-pulse rocket motor has the advantages of a large killing area, dual-range attack capability, and good maneuverability compared with conventional engines. The pulse engine can provide an advanced power platform for air defense and anti-missile missiles, ground-to-ground ballistic missiles and other weapon systems, thereby improving the interception accuracy of air-defense and anti-missile missiles and enhancing the ability of ground-to-ground ballistic missiles to change orbits and penetrate defenses. As the core component of the pulse engine, the isolation device divides the engine combustion chamber into several parts, enables the engine to be shut down and started multiple ...
