requirement using slave M61 or M61A1 guns or Government approved test
equipment of the contractor's design (see 4.5.6.2) which simulates the
function of the gun. Two belts of 100 rounds each of linked ammunition
shall be used for testing each feeder and a steady state torque load
of 80 10 pound-inches shall be applied to the booster take-off ass-
embly drive point during functioning. The feeders shall be accelerated
up to a feeding steady state rate of 4,000 to 4,4000 rounds per minute
before the feeder is declutched at fire-out (without ammunition
in feeder). The feeder solenoid shall be energized to declutch the
feeder at the instant power to the drive is removed, and shall not be
energized for more than 15 seconds at any one time. After feeding
each belt of ammunition the recorded data shall be checked to assure
proper operation of the declutching mechanism. Instrumentation shall
be of the contractor's design and shall be such that gun speed curve,
timing marks, primer impulse, feeder declutching actuation and booster
take-off torque load is taken and recorded concurrently for use in
computing required data for each feeder.
