SUPERSONIC BIROTATING JET SHELL Russian patent published in 2008 - IPC F42B15/00 

FIELD: weapons.

SUBSTANCE: invention concerns combat equipment. The supersonic birotating jet shell contains mechanisms of a course control at angles of pitching, hunting and heeling with drives, the case of the asymmetric form, made of rotating and unrotative parts. An explosive device, control system, a tank with fuel, supersonic birotating gas turbine engine using liquid fuel, containing an air inlet, a compressor, chamber of combustion and a turbine, creating an internal and external rotors divided with bearing supports is established inside the case. The internal rotor consists of a rotor of the compressor and the turbine driving wheel, and the external rotor consists of a supersonic air inlet, a compressor stator and the combustion chamber, and is rigidly connected to a rotating part of the case. The tank with fuel is connected to the combustion chamber using an engine feed line where the fuel pump with a pump drive is established. The supersonic jet nozzle is executed as an unrotative part of the shell and established on bearing supports between internal and external rotors and executed with possibility of regulation of a thrust vector.

EFFECT: increase of shell flight speed, firing range and accuracy and expansion of shell functionality.
