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

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement elements of systems of missiles control and stabilisation, for instance, missiles of volley fire systems. Hydrodynamic gyroscope comprises body, rotor rotated from external electric motor and provided with spherical cavity, partially filled with liquid, spherical float arranged in it with permanent ring magnet installed in its equatorial plane, cylindrical magnetic conductor with fixed hollow cylindrical frame with circular bore on external surface, where two circular ledges are provided as arranged symmetrically relative to circular bore. In each circular ledge there are four slots provided parallel to generatrix of hollow cylindrical frame, and in diametral slots there are rectilinear sections of support windings turns laid parallel to axis of rotor rotation. Spherical cavity is filled with fluorine-organic liquid - Freon 114 B2 with content of mass fraction of water in it of not more than 0.002%.

EFFECT: invention will make it possible to increase accuracy and reliability of gyroscope.
