Closed loop fluidic angular rate gyro

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, said output signal being proportional to the angular velocity of said gyro about said sensitive axis, said responsive means being comprised of means for applying first and second fluidic signals to said sensing means at approximately equal respective distances from said torsional axis, the resultant pressure differential applied to said sensing means providing the restoring torque necessary to return said sensing means to the normal null position, and causes the generation of a differential output pressure signal proportional to movement of said sensing means about said torsional axis.
