METHOD OF MEASURING ANGULAR DEVIATIONS OF ROTOR OF THREE-DEGREE GYROSCOPE RELATIVE TO ITS HOUSING AND ROTOR RPM Russian patent published in 2019 - IPC G01C19/28 

FIELD: measurement.

SUBSTANCE: invention relates to the gyro measuring systems construction methods. Method of measuring angular deviations of a rotor of a three-stage gyroscope relative to its housing and rotation speed of the rotor comprises steps of determining angular deviations of the rotor of the gyroscope from the difference in the output voltages of the amplitude detectors connected through matching transformers with inductance coils with dumb-bell-like ferrite cores arranged on the gyro body symmetrically about its longitudinal axis and at a certain distance from the end surface of the rotating ferromagnetic rotor, on which there is an even number of equally spaced apart permanent magnets with alternating polarity and axial magnetisation, and rotor speed of gyroscope is determined from frequency of alternating voltage on windings of inductance coils, and end surface of rotor is made so that to exclude possibility of magnet movement after their installation and during rotation of rotor.

EFFECT: technical result is measurement of angular deviations of three-stage gyro rotor relative to its housing in a sufficiently large range of angles and measurement of rotation speed of gyroscope rotor in conditions of absence of power supply and during operation of gyroscope in run-out mode of rotor.
