ABSTRACT:
The gyroscope includes a symmetric and concentric, freely vibrating cylinder. Electromagnetic forcers are arranged to apply forces on the cylinder to excite the cylinder's lowest order radially oscillating mode. The forcers also steer the resulting nodal pattern of the cylinder. The cylinder nodal pattern is sensed and a servo selectively excites the forcers to steer the nodal pattern to its original configuration in the presence of cylinder rotations. The forcer steering commands are related to the rotation rate of the gyro. The vibrating cylinder is free of any attachments or deposits and is machined accurately to eliminate the need for balancing, resulting in low temperature sensitivity.
