BODY OF SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 2007 - IPC F02K9/34

Abstract RU 2304726 C2

FIELD: rocketry, mainly such systems as aircraft rocket projectiles, salvo-fire jet systems and zero stages of anti-aircraft guided missiles.

SUBSTANCE: the body of the solid-propellant rocket engine has a body proper and a nozzle unit made integral with it. The inner surface of the body and nozzle unit being in contact with the solid propellant combustion products is protected by a heat-resistant coating. The body and the nozzle unit are made by isothermal stamping of a tube based on an aluminium alloy. The heat-resistant coating is made erosion-resistant based on an anode film of aluminium oxide, up to 60 μm thick. The nozzle unit is made with tail unit attachments.

EFFECT: simplified manufacturing method, enhanced reliability, safety and passive weight of the body.
