REQUIREMENTS (Continued)
Applicable paragraphs
of MIL-S-22518A(AS)
Phase A:
The ATS/AD shall accelerate the flywheel
having a olar moment of inertia of
430
for a period of 8 seconds
from rest.
Phase B:
After a period of 8 seconds from rest,
a torque load shall be applied to
maintain the pad "A" drive speed at a
constant value
RPM) for a period
of 10 seconds.
Phase C:
At the end of phase B the torque load
shall be removed and the ATS/AD allowed
to accelerate the flywheel to cutout speed
or for an additional period of 12 seconds,
whichever occurs first. Upon completion
of the 12-second period or phase C if cutout
speed has not been obtained, the ATS/AD
shall be motored by an external source to
a speed that will cause the automatic
shutoff controls to operate.
Accessory Drive: After the ATS/AD temperature has
been stabilized for a minimum of 8 hours at
-65 F, the ATS/AD shall be operated at a -65F
ambient air temperature at 3500 RPM input at Pad
"A" for a period of 5 hours with a 55 HP continuous
load applied at pad "B," and 7200 RPM for 5 hours
with a 55 HP continuous load applied at pad "B."
An 82 HP load shall be applied for 2 minutes once
during this test at each of the above speeds. A
110 HP load shall be applied for 5 seconds twice
during this test at 4000 RPM and 7200 RPM.
4.5.11.2
High Temperature Operation:
Starter: The inlet air pressure and temperature
and the stabilized ATS/AD temperatures for the
high temperature test shall be as follows:
ATS/AD Temperature
Inlet Air Total
