PROCEDURE MEASURING ANGULAR VELOCITY BY SINGLE-DEGREE-OF- FREEDOM ROTOR VIBRATORY GYROSCOPE Russian patent published in 2003 - IPC

FIELD: gyroscopic instruments. SUBSTANCE: invention refers to single-degree-of-freedom vibratory gyroscopes with variable angular velocity of drive used to measure angular velocity of mobile objects, specifically, to single-degree-of-freedom vibratory gyroscopes employed to measure angular velocity with reference to equatorial axis of rotating aircraft in which bank rotary aircraft itself is drive. From electric signal of angle-data transmitter of sensitive element with reference to fuselage information on angular velocity of drive is extracted in correspondence with which gain factor corresponding to present value of angular velocity of drive of rotor vibratory gyroscope is computed. Then signal from angle-data transmitter of sensitive element of rotor vibratory gyroscope is divided by value equal to present value of gain factor and goes after this to measurement network. Amplitude of electric signal fed into measurement network is proportional to value of measured angular velocity and does not depend on angular velocity of drive. EFFECT: increased precision of single-degree-of-freedom rotor vibratory gyroscope untuned dynamically under variable angular velocity of drive. 1 dwg
