3.2.6 Threads. Unless otherwise specified, all threads shall be
in accordance with National Bureau of Standards Handbook H28. The class
or fit for threads shall be as specified on the applicable drawings.
3.2.7 Dimensions. The maximum physical dimensions of the rate gyro
shall conform to Dwg 1503477.
3.2.8 Wiring. The rate gyro shall be wired in accordance with Dwgs
859607 and 1503477.
3.2.9 Conflicting requirements. In the event of conflict between
this specification and other documents referenced herein, the require-
ments of this specification shall apply.
3.3 Performance requirements and product characteristics. The rate
gyro shall have the product characteristics and meet the performance
requirements given below:
All line, plug, and connector designations referred to in this
section are shown on Dwg. 1503477.
3.3.1 Angular rates.
188.8.131.52 The rate gyro described herein shall be capable of measuring
angular rates from 0 degrees per second to 33 degrees per second with a
tolerance of plus 11 minus 0 degrees per second.
184.108.40.206 The rate gyro shall be capable of measuring the angular
rates described in 220.127.116.11 in a clockwise and a counterclockwise direc-
tion when rotated about an axis that is mutually perpendicular to the
spin axis and the gimbal axis.
3.3.2 Sensitivity. The rate gyro sensitivity shall be 0.21 0.02
volt per degree per second when feeding a 25,000 250 ohm resistive
load, and with a 55 1 volt, 400-Hertz(Hz) microsyn input. The distor-
tion of the input voltage to the microsyn shall not exceed 1.0 per-
This sensitivity requirement applies to angular rotations as des-
cribed in 18.104.22.168.
3.3.3 Maximum output. The rate gyro maximum output, when feeding a
25,000 250 ohm resistive load, and with a 55 1 volt microsyn input,
shall be 8 0.25 volts.
3.3.4 Phasing. The output voltage on terminals F and H of P601
shall be in phase with the supply voltage (terminals D and E, respect-
ively) when the following conditions exist:
