NOZZLE OF SOLID-PROPELLANT ROCKET ENGINE

摘要

FIELD: rocketry. SUBSTANCE: proposed nozzle of solid-propellant rocket engine contains supersonic profiled bell mouth with conical end part. Angle of semiopening of conical end part of nozzle is 16.5o - 21o. Conical section conjugates with profiled section in section where angle of tilting of tangent line to nozzle profile is equal to angle of semiopening of conical end part. EFFECT: prevention of erosive destruction of bell mouth. 1 dwg
