SOLID ROCKET FUEL CHARGE FOR ROCKET ENGINE

摘要

FIELD: rocket technology. ^ SUBSTANCE: construction of solid rocket fuel charge includes solid fuel stick with central channel and two-layer end armoring. Inner armoring layer is performed of armor material, is mounted close to the fuel stick and provides high adhesion to the thermal elastoplastic based fuel which is plastificated with indene coumarone resins. Outer armoring layer is performed of an electric carton that has high damp ability. Inner armoring layer connection to the fuel charge by butyl acetate based glue. Outer armoring layer is connected to the inner armoring layer by gluing compound that is based on thermal elastoplastic and indene coumarone resin. ^ EFFECT: increase of summary charge propulsive burn and thickness decrease of the inner armoring layer of the end armoring. ^ 2 dwg
