Project 5.6 - In-Flight Participation of an FelOlA - Capt. H. M. Lewin
Objective
The objective of Project 5.6 was todetermine the responses of an
in-flight F-101A aircraft to the thermal, blast and gust effects of a
nuclear detonation,
INSTRUMENTATION
The aircraft was instrumented with radiometers, calorimeters and
pressure transducers to measure the thermal and blast inputs and with
Strain gages, thermocouples and various other instruments to measure
the aircraft responses to the inputs.
For the
«.
(FLATHEAD) shot,
the airexatt was positioned theoretically to undergo a temperature rise
me. the .020 skin covered honeycomb surfaces of the aircraft
besed on the positioning yield and the on time position.
A anal honey-
comb test panel was painted black to receive a AT of
basis,
on the same
At this position, the aircraft would receive 6 percent design
limit torque on the stabilizer.
Aircraft Position in Space
The aircraft was to fly at 28,000 feet absolute on an inbound head=
ing of 124° at a ground speed of 600 fps.
It was planned that the aire
craft would be over ground zero at To with shock arriving 26 seconds
later at a horizontal range of 20,800 feet.
Actual shot day position
was 385 feet short and 120 feet to the right of ground zero at Tp with
shock arriving 27.58 seconds later at a horizontal range of 22,585 feet.
