Project -5«3 - In-Flight Partici phtan of A B-66B - R. W. Bachman
OBJECTIVE
The primary objective of this test was to measure the thermal
effects of a large yield nuclear airburst on a B-66B aircraft in flight.
INSTRUMENTATION
Instrumentation of the B-66 for
CHEROKEE) con-
sisted of 60 thermocouples and 73 strain gagewet 7 stations on the
left wing, 9 thermocouples and 10 strain gages at 2 stations on the right
wing, 34 thermocouples and 18 strain gages at 7 stations on the left
stabilizer, and 9 thermocouples and 12 strain gages at 3 stations on
ss
the right stabilizer, plus 63 channels of correlating information,
AIRCRAFT POSITION IN SPACE
Because of discrepancy in count-down, the B-66 flew an abort pattern
which, at H-hour, positioned the aircraft 46 degrees from tail-on and
right-side to actual GZ on a heading of 251 degrees with a true air speed
of 495 knots.
The absolute altitude and horizontal range at H-hour were
36,000 feet and 52,640 feet respectively.
The absolute altitude hori-
zontal range and heading at shock arrival (H 4 125 seconds) were 36,000
feet, 143,000 and 251 degrees respectively.
