Abstract

A moulding method for a long-dimension separator sleeve of a pulse motor is disclosed. The method includes: according to product structure characteristics and function characteristic requirements, determining the thickness of a thermal insulation layer and the thickness of a fiber composite layer and preparing a pouring mould and a metal connecting part for sleeve moulding; preparing a connector comprising the metal connecting part; installing the connector to a moulding mandrel; manually pasting the surface of the moulding mandrel, which is not covered with the connector, with a thermal insulation material; winding the surface of the manual pasting layer with fiber dry yarn; vulcanizing to obtain a base layer of the thermal insulation layer; fully dipping carbon fiber in an epoxy resin solution; winding the surface of a carbon fiber cloth with carbon fiber in a wet manner to obtain a fiber composite layer; manually pasting the surface of the composite layer with the thermal insulation material continuously; and vulcanizing to obtain the long-dimension separator sleeve of the pulse motor. The method is suitable for moulding of the separator sleeve reinforced by a resin-based composite material. The separator sleeve mainly comprises a nonmetal material, is small in product total weight, and facilitates passive mass reduction of motor shells.

Description

technical field [0001] The invention relates to a molding method for a pulse engine casing, in particular to a molding method for a long-dimension partition sleeve of a pulse engine. Background technique [0002] As an advanced power system, the dual-pulse rocket engine has the advantages of dual-range attack capability, large killing area, good maneuverability, and large no-escape zone 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. The isolation device is the core component of the pulse engine, which reasonably distributes the thrust and the interval time of each pulse to realize the optimal management of the engine energy. [0003] There...
