Project 5,1 - In-Flight Participation of a B-47 Afreraft - Lt, R. C. Laumann
OBJECTIVE
The objective of this project is to measure the blast, gust, and
thermal effects of a nuclear detonation on an in-flignt B47 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 provide basic research data for the design criteria of future USAF
Jam
aircraft,
INSTRUMENTATION
Two hundred seventy three data channels were available on this shot
to record bending, shear, and torsion in the wing and horizontal stabilizer,
thermal inpute to the aircraft, thermally induced strain, temperature
measurements, and overpressure,
Prior to shot participation 97.0% of
these channela were operating aatisfactorily,
There has been no newly
adied instrumentation since the last participation,
AIRCRAFT POSITION IK SPACE
The B-L7 was flying at an absolute altitude of 30,000 feet,a speed
of Mach C,75, and on a heading of 320° at both To and shock arrival,
The
alreraft was orlented tail to the shot; at Ty the horizontal range beyond
ground zero was 29,000 feet, and at shock arrival it was approximately
