UNIAXIAL HORIZONTAL INDICATOR GYROSTABILIZER Russian patent published in 2021 - IPC G01C19/44 

FIELD: gyroscopic equipment.

SUBSTANCE: invention relates to gyroscopic equipment, it can be used as a part of uniaxial or biaxial gyroverticals built based on indicator gyroscopic stabilizers and performing a movement close to horizontal. The uniaxial horizontal indicator gyrostabilizer contains three-stage gyroscope 2 mounted on platform 1 in a uniaxial suspension so that the axis of outer frame 5 of gyroscope 2 is directed along the axis of the suspension of platform 1, the electric caging, correction and stabilization circuits, as well as the compensation circuit to eliminate the turning error. The electric caging circuit, consisting of second angle sensor 9, caging amplifier 12, and first torque sensor 8 connected in series, supports the kinetic torque vector of gyroscope 2 rotor perpendicular to the axis of outer frame 5. To stabilize platform 1 in a given position, an indicator stabilization circuit is used, consisting of serially connected first angle sensor 7, connected to the first input of stabilization amplifier 11 by the type of negative feedback, and stabilizing motor 14, as well as additional resistor 19, included in the power supply circuit of the rotor of stabilizing motor 14, the output of which is connected to the second input of stabilization amplifier 11 by the type of positive feedback to introduce additional damping relatively to the stabilization axis. The correction circuit, consisting of serially connected pendulum sensor 3, adder 18 (second input), correction amplifier 13, and second torque sensor 10, brings the platform to a horizontal position. To eliminate the influence of centripetal acceleration when moving an object along curved sections of the path, a compensation circuit is introduced, consisting of angular velocity sensors 4 and linear velocity sensors 16, connected to the inputs of multiplication unit 17, the output of which is connected to the first input of adder 18, and the parameters of the compensation circuit are related by the ratio , where are the transmission coefficients of the angle sensor of the pendulum sensor, the linear velocity sensor of the object, the angular velocity sensor and the multiplication unit; g is the acceleration of free fall.

EFFECT: expansion of the functionality of the horizontal indicator gyrostabilizer and increased accuracy of operation when the object moves on a turn.
