SOLID-PROPELLANT CHARGE FOR ROCKET ENGINE OF AIRCRAFT ROCKET

摘要

FIELD: engines and pumps. ^ SUBSTANCE: solid-propellant charge for rocket engine of aircraft rocket includes solid-propellant grain armoured along side surface and front edge with a star-shaped channel. Star-shaped channel includes uniformly alternating projections and cavities the height and thickness of which is determined with relationships protected with this invention. Conical turned part is made at the rear edge of charge along outside diameter of the charge at the length of 0.05Ç0.07 of solid-propellant grain length, at an angle of 18Ç20 to longitudinal axis of charge. ^ EFFECT: invention allows improving specific impulse of solid propellant engine thrust and reducing the action of engine flame of the rocket that is launched from under the aircraft fuselage on operability of aircraft engine. ^ 4 dwg
