FIELD: engines and pumps.SUBSTANCE: when preparing an inner surface of the body prior to filling of composite propellant, a heat-shielding coating is applied on the inner surface of the engine body, made with a protective-reinforcing later comprising a sealing rubber layer and a layer of a volume elastic tissue with developed surface. Prior to filling of the composite propellant into the body, the volume tissue is removed with the developed surface of the protective-reinforcing layer.EFFECT: invention makes it possible to simplify preparation of an engine body prior to pouring of composite propellant in it without reduction of strength of fuel adhesion to a body, and also to reduce engine passive mass. |
