FIELD: rocket equipment.
SUBSTANCE: rocket engine of solid fuel with charge of end combustion of large length and small diameter, formed directly into engine housing, includes housing, charge and nozzle unit. Housing consists of composite power shell, inner heat-insulating coating, front collar and armoured casing. Due to the fact that the armoured case is connected to the body only in the head of the article, and on the rest of its length it is detached (separated) from the body, the charge has the possibility of changing its length and diameter at change of ambient temperature without strains in solid fuel. On the internal surface of the heat-insulating coating of the housing, in the zone of detachment of the armoured case, there are longitudinal grooves for passage of combustion products.
EFFECT: disclosed is solid propellant rocket engine.
