Claims (3)

1. Способ изготовления корпуса ракетного двигателя твердого топлива из композиционного материала, заключающийся в установке на оправку внутреннего теплозащитного покрытия, намотке поверх его силовой оболочки из полимерного композиционного материала с последующей полимеризацией, отличающийся тем, что между оправкой и внутренним теплозащитным покрытием устанавливают изолированную антиадгезионной пленкой манжету из эластичного материала.1. A method of manufacturing a housing of a solid propellant rocket engine from a composite material, comprising installing an internal heat-shielding coating on a mandrel, winding a polymer composite material over its power sheath, followed by polymerization, characterized in that an insulated cuff is installed between the mandrel and the internal heat-shielding coating from elastic material. 2. Способ изготовления по п. 1, отличающийся тем, что манжета выполнена из силикона с толщиной стенки, соизмеримой с толщиной внутреннего теплозащитного покрытия.2. A manufacturing method according to claim 1, characterized in that the cuff is made of silicone with a wall thickness commensurate with the thickness of the inner heat-shielding coating. 3. Способ изготовления по п. 1, отличающийся тем, что манжета выполнена в виде герметичного мешка, который в процессе полимеризации силовой оболочки корпуса нагружают гидравлическим давлением, превышающим контактное давление на оправку, создаваемое усилием намотки материала силовой оболочки.3. The manufacturing method according to p. 1, characterized in that the cuff is made in the form of a sealed bag, which during the polymerization of the power shell of the body is loaded with hydraulic pressure exceeding the contact pressure on the mandrel created by the winding force of the material of the power shell.
