Project 5.1 ~ In-Flight Participation of a B-47E Aircraft ~ 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-flight B-47E aircraft.
With the
recorded data, the criteria and method used in the B-L4’7E Weapon Delivery
Handbook may be verified or corrected.
In addition, the project will provide
basic research data for the design criteria of future USAF aircraft.
INSTRUMENTATION
Two hundred seventy three data channels were availatle on this shot to
record bending, shear and torsion in the wing and horizontal stabilizer,
thermal inputs to the aircraft, thermally induced strain, temperature measurements, and overpressure.
Prior to shot participation, 97% of these channels
were operating satisfactorily.
There has been no newly added instrumentation
since the last participation,
AIRCREFT POSITION IN SPACE
The B-A7E was flying at an absolute altitude of 35,000 feet, a speed of
Mach 0.75 and on a heading of 270° at both zero time and shock arrival time.
The aircraft was oriented tail to the shot; at zero time the horizontal range
beyond ground zero was 26,000 feet and at shock arrival it was approximately
66,400 feet.
RESULTS
A 313°F temperature rise was measured in the 0.020 inch 24ST eluminum
right aileron unpainted test panels.
A 258°F temperature rise was recorded
on the 0.025 aluminum unpainted right elevator,
