1. A closed loop fluidic angular rate gyro having a single sensitive axis, comprising:

  • a. a supporting member;

    b. means for sensing movement of said gyro about said sensitive axis;

    c. means for pivotally mounting said sensing means to said supporting member and about a torsional axis which is perpendicular to said sensitive axis to maintain said sensing means in a normal null position and allow rotation of said sensing means about said torsional axis in response to the angular velocity of said gyro about said sensitive axis;

    d. means responsive to movement of said sensing means for providing a restoring torque to return said sensing means to said normal null position and for producing an output signal proportional to movement of said sensing means about said torsional axis, whereby said output signal is proportional to the angular velocity of said gyro about said sensitive axis; and

    e. said sensing means being comprised of a coil having a fluid flowing therethrough in a plane substantially parallel to a plane established by the intersection of said torsional axis and said sensitive axis when said coil is in the normal null position, whereby the angular momentum of said fluid flowing through said coil causes an angular displacement of said coil about said torsional axis in response to the angular velocity of said gyro about said sensitive axis.
