APPENDIX
(2) Ejection seat and dummy combination.
Mass moment of inertia about each of the three axes and the
e.
cross-moments of inertia for each combination of ejection
seat and different sized dummy.
f.
Elevation of the seat intersect point above the test facility
ground level reference point (after final ejection seat
adjustment).
g.
Location and orientation in three dimensions with respect to
the applicable reference point for each motion picture camera,
transducer, and probe. Each locating dimension shall be
established within an accuracy of 1 percent of the distance
to the applicable reference point.
Photographs of test article buildup, as required.
h.
Installation photographs showing critical configurations,
i.
connections, and riggings as required.
Instrumentation system calibration data as specified in the
j.
test plan and consistent with the test facility's standard
calibration procedures.
Data verifying that dummy installation complies with the
k.
dummy positioning standards included in the test plan.
30.3.2 Test data. As a minimum, test performance data specified below
shall be measured and permanently recorded as functions of elapsed test time.
All continuous and discrete event electronic signals and all photographic
data shall be synchronized to provide a common time base for all test records
Timing shall continue to an end of test time reference point following touch-
down of the last test article or dummy. The minimum data that shall be
specified in the test plan shall include the following items:
Electronic:
a.
Linear accelerations and linear and angular velocities
(1)
for the test vehicle, test article and dummy, aS
appropriate. Ejection seat linear accelerations shall
be obtained redundantly.
(2) All pertinent signals (electrical, ballistic, pneumatic,
etc.) and all ballistically generated actuation pressures.
(3) Catapult pressure~
(4) All pertinent non-ballistic pressures related to escape
system parameters such as altitude, airspeed, reservoir
charge level, etc.
(5) Forces acting on critical devices such as parachute
risers, drogue bridle(s), restraint straps, etc.
(6) Discrete event times.
(7) Impulse noise levels (zero speed tests only).
