TORSIONAL RATE SENSOR WITH MOMENTUM BALANCE AND MODE DECOUPLING

摘要

Rate sensor having a plurality of generally planar masses, means for driving the masses to oscillate about a drive axis in the planes of the masses, an input axis perpendicular to the drive axis, sense axes perpendicular to the drive axis and the input axis, means mounting the masses for torsional movement about the sense axes in response to Coriolis forces produced by rotation of the masses about the input axis, and means responsive to the torsional movement about the sense axis for monitoring rate of rotation about the input axis.
