METHOD FOR LAUNCHING GUIDED PROJECTILE AND GUIDED PROJECTILE FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC F42B15/00 

FIELD: weapon.

SUBSTANCE: group of inventions relates to guided projectiles. The projectile contains an engine with channel propellant charge and ignition charge. A flange is fixed on the front end face of the propellant charge. A cavity containing the ignition charge is formed between the cover of the engine and flange. The cavity is connected with the channels of the propellant charge and cavities between its surface and the one of the engine by the inclined blast tubes. The projectile is launched together with thermogas dynamic ignition of the part of the propellant charge's surface using combustion products of the ignition charge disposed opposite to a nozzle block. The surface of the channels and outer surface of the propellant charge are also exposed to thermogas dynamic ignition by combustion products of the ignition charge at the same time. From the side of the ignition charge the surface of the propellant charge is isolated from exposure of thermogas dynamic jet, and combustion products of the ignition charge are removed in radial directions and before entering the channels of the propellant charge they are turned around towards the surfaces of the channels and the outer surface of the propellant charge.

EFFECT: reliable and stable engine run of the guided projectile with high thrust at high flight loading is provided.
