METHOD OF PRODUCING OF HOUSING OF ROCKET SOLID PROPELLANT ENGINE Russian patent published in 2017 - IPC F02K9/34

Abstract RU 2614422 C2

FIELD: machine building.

SUBSTANCE: invention relates to the machine building, namely to the method of producing of the housing of rocket solid propellant engine out of composite material received by a method of continuous winding of reinforcing tape. The method of producing of the housing of rocket solid propellant engine out of composite material means installation in mandrel of the internal heat insulating material, winding over it of the power enclosure out of polymer composite material with further polimerization, wherein between the mandrel and internal heat insulating coating a cuff isolated with antiadhesion film is installed, the cuff is made out of elastic material, for example silicone with wall thickness corresponding to thickness of the internal heat insulating coating. The cuff can be made in form of tight bag, that during polymerization of the power enclosure of the housing is loaded by the hydraulic pressure exceeding the contact pressure on the mandrel and created by winding force of the power enclosure material.

EFFECT: invention ensures increased strength and adhesion characteristics of the housing bottom design.
