ABSTRACT:
Disclosed is a roll rate sensor which may form part of a roll position sensor (an "up-sensor") and which comprises a vibratory element rotated by a motor within a projectile body so its rotation speed about the projectile axis is the sum of the motor speed and the projectile roll rate. The resultant centrifugal force acts on the element so as to vary its effective stiffness and hence its vibration frequency. A transducer is arranged to provide a signal corresponding to the vibration and hence to the centrifugal force and the roll rate. The vibratory element may comprise a metallic or silicon beam element.
