Abstract:

THE RESULTS ARE SUMMARIZED OF THE MODIFICATION AND SUBSEQUENT TEST PROGRAM DIRECTED TOWARD THE INCORPORATION OF A SPIN-MOTOR ROTATION MONITORING DEVICE IN THE HIG-4 GYRO. THE MODIFICATION CONSISTS PRIMARILY OF INCLUSION OF A VARIABLE RELUCTANCE SIGNAL PICKOFF WITHIN THE GYRO GIMBAL OR FLOAT. THE PICKOFF IS DESIGNED TO DEVELOP TWO VOLTAGE PULSES PER REVOLUTION OF THE MOTOR WHEEL. THUS, AT A MOTOR SPEED OF 400 REVOLUTIONS PER SECOND, A SIGNAL OF 800 PULSES PER SECOND IS GENERATED.THE DURATION AND PEAK-TO-PEAK AMPLITUDE OF EACH PULSE ARE APPROXIMATELY 0.4 MILLISECOND AND 0.2 VOLT, RESPECTIVELY, ACROSS A 600-OHM LOAD RESISTANCE. GYROS INCORPORATING THESE DESIGN CHANGES WERE EXPOSED TO HIGH AND LOW TEMPERATURE, SHOCK, VIBRATION, AND ACCELERATION QUALIFICATION TESTS. PICKOFF PERFORMANCE WAS UNAFFECTED BY THESE ENVIRONMENTS
