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

FIELD: weapons.

SUBSTANCE: invention concerns combat equipment and is intended for conducting fight and struggle against terrorists. The birotating jet shell contains controls of a course of movement of a shell on pitch angles, hunting and heeling, the case of axisymmetric form made of rotating and unrotative parts. The explosive device, control system devices, drives of course of movement controls, hunting and heeling, a fuel tank, a birotating gas turbine engine with the jet nozzle, working on liquid fuel and containing air inlet, compressor, combustion chamber and a turbine, forming an internal and external rotors divided by bearing support, are established in the case. Thus the rotor of the compressor and the turbine driving wheel form an internal rotor, and an air inlet, the compressor stator and the combustion chamber form an external rotor which is rigidly connected to a rotating part of the case. The tank with fuel is connected via engine feed line with the fuel pump with a pump drive established, to the combustion chamber, and the jet nozzle is executed as an unrotative part of a shell and established on a bearing support between the internal and external rotors. Controls are executed in the form of four rotary aerodynamic wheels.

EFFECT: increase of firing accuracy and expansion of shell functionality.
