Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] The invention discloses a compound winding mandrel with medicine, which is integrated with the propellant and the heat insulation layer by using the mandrel charged with the medicine, and meets the forming requirements of the wound compound shell with medicine. Surface molding, using the core column as the winding shaft, enhances the strength and rigidity of the compound winding mandrel with medicine, meets the requirements of charging and winding at the same time, and avoids the problems of complex structure and cumbersome molding process of the compound winding mandrel with medicine .

[0058] Light weight and high energy are the development trend of the new generation of solid rocket motors. The composite shell is made of non-metallic materials. The application of high-strength ratio fiber materials can effectively reduce the ...

Abstract

The invention discloses a propellant-carrying winding combined core mold which comprises a grain assembly, a connecting rod (6), a butt-joint nut (7), an outer coating layer (8), a butt-joint plug (9)and an axial sealing structure; the grain assembly is divided into two parts; a charging core mold is integrally formed with a propellant and a heat insulation layer, the forming requirement of a propellant-carrying winding composite shell is met, and the heat insulation layer and a propellant profile are formed through a charging process; and a grain is adopted as a winding shaft, the strength and rigidity of the propellant-carrying winding combined core mold are enhanced, meanwhile the charging and winding requirements are met, and the problems of too complex structure, tedious forming process and the like of the propellant-carrying winding combined core mold are avoided.

Description

technical field [0001] The invention relates to a compound wound mandrel with medicine, which belongs to the technical field of solid rocket motor composite shells. Background technique [0002] Conventional fiber-wound composite shell molding adopts ablation mandrel or split mandrel, and the process is mandrel molding-shell molding-powder charging, and the process is relatively complicated. For tactical missiles, the diameter of the projectile body is small, and the complex burning surface of the propellant requires large front and rear openings in the shell to realize the charging process. The existence of large openings greatly affects the fiber efficiency of the composite shell. play. Contents of the invention [0003] The technical problem solved by the present invention is: to overcome the above-mentioned deficiencies in the prior art, to provide a compound wound mandrel with medicine, which can meet the forming requirements of the wound composite shell with medicin...
