FIELD: explosives.
SUBSTANCE: method for manufacturing of item from mix rocket solid propellant (MRSP) includes moulding of item, execution of staged hardening of item under pressure by means of coolant temperature variation and item cooling. Item is hardened at initial stage at the temperature of coolant 5-15°C below temperature of the main hardening mode for 10-20% of overall hardening duration, and then in the main mode at the temperature of 60 - 80°C. Cooling is carried out at coolant temperature of 10 - 35°C and duration (τcooling, hr), defined by formula τcooling=0.61 Taverage + 0.65, where Taverage is actual average coolant temperature, °C.
EFFECT: invention makes it possible to reduce duration of item cooling process.
