FIELD: rocket technology.
SUBSTANCE: rocket part of a rocket projectile containing a body, a charge of solid rocket fuel, a nozzle, a cuff with a conical skirt facing the nozzle inlet cone, a nozzle inlet cone liner and an ignition device, wherein the skirt is made with a cone angle (α) equal to (0.45…1.3) of the cone angle of the liner above the skirt (ϕ), the outer diameter of the skirt (Dso) is (0.75…0.99) times the outer diameter of the cuff (Dco), and the thickness of the skirt (δ) is chosen equal to (0.007…0.045) times the outer diameter of the cuff, and the distance (L) from the igniter to the end of the cuff is (0.45…1.95) of the outer diameter of the cuff, wherein the cuff is made of a material with specified tensile strength parameters.
EFFECT: improved reliability of the rocket part in the process of reaching the operating conditions in the given temperature range by reducing the likelihood of violating integrity of the solid fuel charge.
