Project 5.5 - In-Flight Participation of F-S4F Aircraft - lst Lt. R. F, Mitchell
Objective
Waiter (Capabilities F-48F) - This participation was an attempt to
determine the capability of the F-S4F aircraft by subjecting it to both
thermal and symmetric blast loads.
Barley (Sideloads F-84F) - The objective of this participation was
to study the dynamic response of fighter structures to anti-symmetric
blast loads,
Instrumentation
«
Waiter - 100 data channels were available to record moment, shear,
and torsion loads; thermal strain; temperature rise; overpressure; accel~
erations; and aircraft altitude.
that failed.
Of these channels, there were 2 channels
In addition, a flap camera and an NRDL camera were inoperat=
ive.
Barley - Out of the 100 data channels available to record essentially
the same information as above, there were 3 channels that failed.
Aircraft Position in Space
Waiter - At time zero, the aircraft was flying at an absolute altitude of 21,000 feet on an inbound heading of 1259,
was -740 feet with zero offset.
The horizontal range
The shock arrival position (at H¢18.99 sec)
was 21,000 feet altitude and 10,900 feet horizontal range.
The true air~
speed was maintained at 800 ft/sec.
Barley - At time zero, the aircraft was flying at an absolute altitude
of 18,000 feet on an inbound heading of 0979,
The horizontal range and off-
set were -22,400 feet and 34,400 feet respectively,
