HYDRODYNAMIC GYROSCOPE Russian patent published in 2011 - IPC G01C19/20 

FIELD: weapons and ammunition.

SUBSTANCE: gyroscope comprises a body, a rotor with a spherical cavity, partially filled with fluid, a motor connected by means of a coupling to the rotor axis, a spherical float with a through axial hole, a device of the float axial alignment in the form of a ball, which is rigidly fixed in the centre of the float, and two axial supports installed in the spherical cavity along the axis of its rotation. The motor comprises a spiral flat spring connected in an undetachable manner with its one end to a rim fixed on the body, and with its other end to the bush for spring winding in the inner cavity of the rim, which is installed with the possibility of rotation on the motor shaft. The diameter of the through axial hole in the float and the diameter of axial supports is selected from the ratios D/D_f=0.15-0.2 and d/D_f=0.06-0.09, where D - diameter of the through axial hole in the float, d - diameter of axial supports, D_f - float diameter.

EFFECT: invention makes it possible to reduce time of availability of hydrodynamic gyroscope, which makes it possible to increase firing rate.
