Abstract : A system is presented for sensing the boundary layer around a gyroscope rotor which will provide an electrical signal that is directly proportional to gyro rotor angular offset. The system employs an arrangement of hot film sensors set partially into the rotor boundary layer so that they form two resistors of a Wheatstone bridge circuit for each axis. The hot film resistors change in resistance according to the angular offset from null of the gyro rotor. The combination of resistance changes is then used in the bridge circuit to provide an electrical signal which is directly proportional to gyro rotor angular offset. (Author)
