GYROSCOPIC STABILIZER Russian patent published in 2006 - IPC G01C21/18 

FIELD: gyroscopic instruments; performing function of actuating member in spacecraft control systems.

SUBSTANCE: proposed gyroscopic stabilizer is provided with single-axis gimbal mount where powered gyroscope with electromagnetic supports of rotor and control unit of suspension frame control drive is located. Each electromagnetic support has two pairs of coaxial electromagnets and two-coordinate clearance sensor located in mutually perpendicular directions. Electromagnet pairs are located symmetrically relative to rotor suspension axis. Measuring members of sensor are oriented similarly of electromagnet coils. Outputs of sensor measuring members are connected via radial stabilization unit to electromagnet coils of the same support. Besides that, stabilizer is provided with four units for calculation of centering forces of support electromagnets which are made in form of multipliers and squarers connected in series, two units for calculation of gyroscopic torques made in form of subtracters, adder and current sensors connected with electromagnet coils. Connected to inputs of each unit of calculating centering forces of electromagnets are outputs of current sensors connected with coils of one pair of coaxial electromagnets and outputs of coaxial measuring members of clearance sensor of the same support. Outputs of units used for calculating the centering forces of coaxial pairs of electromagnets of different supports are connected with inputs of gyroscopic torque calculating units whose outputs are connected with adder inputs whose output is connected with input of frame rotation drive control unit.

EFFECT: enhanced stabilization due to reduction of adverse torques acting frame suspension axis.
