DEVICE TO IMPROVE ACCURACY AT FIRING FROM AIRCRAFT GUNS MOUNTED ON HELICOPTERS Russian patent published in 2018 - IPC F41C27/22 F41A21/32 B64D7/06 

FIELD: weapons.

SUBSTANCE: invention relates to the field of armament and can be used to compensate for the deviation of the helicopter relative to its center of mass during firing. Device for improving accuracy includes a gas outlet with inlet and outlet nozzles mounted on the tail of the helicopter and connected by a gas-dynamic connection to the screen-exhaust device of the helicopter propulsion system, valves with electric drives, mounted on the air intake device of the screen-exhaust device, in the exhaust device of the screen-exhaust device and in the outlet nozzle of the gas outlet, and controlled via an electronic control unit. One of the surfaces of the gas outlet is formed by the surface of the tail part of the helicopter. Outlet nozzle of the gas outlet is rotatable for regulating the direction of the jet thrust vector. Outlet nozzle of the gas outlet further comprises a flow controller for regulating the magnitude of the thrust vector.

EFFECT: compensation for the torque acting on the helicopter relative to its center of mass under the influence of the recoil efforts of aircraft guns is provided increasing the accuracy of fire.
