Project 5.1 - In-Flight Participation of a B-47 Aircraft - Lt. R. C, Laumanr
OBJECTIVE
The objective of this project is to measure the blast, gust and thermal
effects of a nuclear detonation on an in-flight B-47 aircraft.
With the
recorded data, the criteria and method used in the B-47 Weapon Delivery
Handbook may be verified or corrected,
In addition, the project will pro-
vide tasic research data for the design criteria of future USAF aircraft,
INSTRUMENTATION
Two hundred and seventy-three data channels were available on thisshot including seventeen new channels at station 1044.0 of the fuselage
to measure bending, shear and torsion from side loads,
The remaining chan-
nels recorded bending, shear and torsion in the wing and horizontal stabiliser, thermal inputs to the aircraft, thermally induced strain, temperature measurements and overpressure,
Prior to shot participation 97% of
these channels were operating satisfactorily.
AIRCRAFT POSITION IN SPACE
The B-47 aircraft was positioned for side-loads effects in this event,
The aircraft was flying at an absolute altitude of 37,000 feet, an offset
of 40,000 feet, a speed of Mach 0,75 and on a heading of 021° at both
Ty and shock arrival,
At T, the shot was ahead and to the left of the
aircraft such that the horizontal range was 32,000 feet short of a point
directly abeam of ground zero,
At shock arrival the aircraft was directly
abeam of ground zero and exactly tangential to the impinging shock wave.
