ROCKET ENGINE OF ARTILLERY CONTROLLED PROJECTILE Russian patent published in 2003 - IPC

FIELD: war material. SUBSTANCE: rocket engine of artillery controlled projectile has housing in form of sectors in cylindrical chambers of which channel propellant charge are installed, front cover and nozzle cover with diaphragm in sectors in form of stepped bushing with gas radial and central channels, and igniter with initiator. Engine is furnished with divider in each sector installed in clearance between propellant charge and sector housing wall and made in form of plate curved to radius. Stepped bushing of each sector is provided with rectangular space and is installed with larger side of rectangular space and radial channels pointed n direction of action of centrifugal forces at rotation of projectile. Radial channels are made diverging , and divider is installed opposite to peripheral channel of stepped bushing at distance from end face of stepped bushing equal to 0.2-0.3 of length of propellant charge. Width of divider plate is 0.1-0.2 of width of outlet of stepped bushing radial channel. Thickness of plate is equal to size of clearance between propellant charge and housing wall. EFFECT: improved reliability of engine at below zero ambient temperature. 2 dwg
