FIELD: heating, fuel.
SUBSTANCE: invention relates to the field of manufacturing of charges of solid rocket fuel (SRF). The method of fastening the restricted-burning charge of solid rocket fuel SRF end burning with the engine body is proposed. The method includes coating of the lateral surface of the charge with an antiblocking agent, preparation and dosing of the fastening polymeric liquid-viscous structure on the bottom of the case covered with an adhesive composition, a centering of the charge relative to the case, immersing the armoured end of the charge to the fastening polymeric liquid-viscous composition and fixation of the charge in the case. As the covering of a lateral surface of the charge with an antiblocking agent a polyethylene tape with a sticky layer is used. On the external surface of the end armour coating of the charge a central protrusion is used. The portion of the fastening polymeric liquid-viscous composition is dispensed into the case from the condition of its displacement to the lateral gap between the case and the lateral surface of the charge.
EFFECT: guarantee of reliability and efficiency in the use of a charge of solid rocket fuel.
