ABSTRACT:
An apparatus for measuring rate of turn employing a vibrating tuning fork type sensor in which the tynes vibrate in a coaxial manner. This arrangement eliminates reaction torques and forces at the base of the tuning fork which allows the tynes to freely deflect into an elliptical pattern during an input turn rate. Sensors are employed which monitor the shape of this elliptical pattern, this shape being proportional to angular turn rate.
