METHOD OF MANUFACTURING SENSITIVE ELEMENT OF CRYOGENIC GYROSCOPE Russian patent published in 2019 - IPC G01C19/24 

FIELD: instrument engineering.

SUBSTANCE: use for the manufacture of cryogenic gyroscope. Invention consists in that the method of manufacturing a sensitive element of a cryogenic gyroscope includes: shaping a spherical rotor, which is a preform of a carbon nanocomposite coated with a superconducting niobium layer, deposition in the zone of the ball zone, in which the axis of symmetry coincides with the dynamic axis of the rotor, and the height is determined by the latitudinal angle α, a raster pattern in the form of equal segments of spherical lines, made with the same angular pitch, the manufacture of two ceramic hemispheres and a centering ring, the formation on the inner surface of the hemispheres of a system of electrostatic suspension, and between the suspension electrodes and on the inner cylindrical surface of the ring there are thin-film measuring turns of superconducting quantum interference sensors, manufacturing optical windows for optical fibers of optical sensor and grooves for accommodating the stator windings of a superconducting magnetic suspension of the rotor in hemispheres walls, the ends of each of the segments of the raster pattern are closed with the ends of at least one of the adjacent segments by bridges, which are performed outside the zone of the said ball zone, forming closed contours on the rotor surface, while the said segments and jumpers are formed in the form of thin-film structures of niobium nitride, and the stator windings of the superconducting suspension are placed and connected to the suspension control elements, forming a multi-phase system ensuring the creation of a rotating magnetic field on the rotor surface.

EFFECT: ensuring the possibility of reducing the time of readiness CG.
