Project 5.) - In-Plight Participation of e B47 Aircraft - Lt, §. C. Leumans
QBIRCTIVE
The objective of this project is to measure the blast, gust and theres]
effects of a nuclear Jetopation on an in-flight B-<7 aircraft,
With the
recorded data, the criteria and metho! use? in the B-i7 Weapon Delivery
Wandbook may be verified or corrected.
In addition, the project will pro-
wide tasio research data for the design criteria of future 08a" afrecraft.
TESTRIREPIATION
Two bundred an’ seventy-three date channels vere available on this
shot including seventeen nev channels at station 1044.0 of the fuselage
te measure bending, shear and torsion from side loads,
The remaining chan-
pele recoried bending, shear and torsion in the ving and horisontal stab-
4liser, thermal inputs to the aircraft, thermally inivesd strain, tempereture measurements and overpressare.
Pricr to shot participation 97% of
theee channele vere operating satisfactorily.
POSITION
The B-47 aircraft was positioned for side-loade effects in this event.
The aireraft wes flying et an ebdsolute altitude of 7,000 feet, an affect
of 40,000 feet, s speed of Mach 0.75 and on « heading of 021° at both
T, and ebook er-ival.
at 7, the shot was ahead and to the left of the
aircraft euch that the horiscntal range was 12,000 feet short of a point
directly abeenm of ground sero,
At shock arrival the aircra’t vas directly
eabeaz of ground sero and exactly tangential to the impinging shook wave,
