ABSTRACT:
A steering rate sensing device for use in the control of a rotating air frame comprises a base member adapted to be secured to the frame for rotation therewith about its rotary axis, a magnetic member pivotally mounted for pivotal movement about an axis transverse to the rotary axis and a coil encircling the magnetic body for sensing and picking up a signal induced by relative angular movement of the magnetic member with the coil. The device responds to gyroscopic effect induced by rotation thereof upon movement of the air frame from its axial orientation to cause the magnetic member to move relative to the sensing coil for generating a signal.
