Project 5.5 = In-Flicht Participation of F-S4F Aircraft ~
Capt R. F. Mitchell
ORIFSTIVE
The objective of this project is to determine the response of
the F-84F weapon system when exposed during flight to the effects
of a nuclear detonation,
INSTRUMENTATION
The instrumentation consistei of strain gage bridges located at
Station 90 ani 150 on the left and right wing; Station 365 on the
fuselage; Flight Station 12 and 35.5 on the left and right stabilizer
and
W. L. 20 and 53 on the fin.
The forementioned strain gage bridges
yielded bending moment information.
Structure responses were related
to energy inputs with overpressure transducers located on a nose boom
and in the sides of the fuselage.
AIRCRAFT POSITION IN SPACE
The planned position of Barley was on an inbound heading of 130°
with an offset of 63,600 feet north and east of ground zero.
The air-
eraft was to be directly side~on to the shock wave at H ¢ 51.5 seconds.
Actual position on shot day was three minutes late at time zero or
approximately 144,000 feet short of the time zero position.
Shock ar-
rival occurred at H 4 135 seconds instead of H # 51.5 seconds, the
calculated value for the on time position.
The miss-positioning of
the aircraft occurred as a result of an error made by the Raydist Con-
