CRYOGENIC GYROSCOPE Russian patent published in 2018 - IPC G01C19/24 

FIELD: measuring equipment.

SUBSTANCE: cryogenic gyroscope comprises a sealed case, a spherical rotor made of superconducting material, a combined rotor suspension comprising a system of superconducting screens installed in the case in pairs along the axes of the suspension on the opposite sides of the rotor and forming a magnetic field in the working gap of suspension, the working surface of each of the superconducting screens facing the rotor is made in the form of a profiled sphere part and forms a variable working gap with a spherical surface of the rotor providing uniform magnetic flux density in the gap, magnetic suspension excitation coils installed above the screens, a magnetic suspension control circuit that generates currents flowing in the excitation coils, an electrostatic suspension control circuit that generates an electric potential on the surfaces of the superconducting forming screens, on the profiled working surface of each superconducting forming screen an optional screen is installed, having an electrical contact with the superconducting forming screen made of material not having superconducting properties, the working surface of which is made in the form of a sphere part and forms an even gap with the spherical surface of the rotor, which ensures density uniformity of electric forces in the gap.

EFFECT: providing the possibility of increasing the accuracy of the cryogenic gyroscope.
