(NAVAJO) Projeet 5,1 - In-Flicht Particirztion of a B-47 Aircraft It Robert ©, Laveann QRITOTIVE The obfective ef this rrojocet is to measure the blast, gust, and thermal effects of a nuclear detonation on an in-flight 9-47 aircraft. With the recorded data, the erit-ria anid method used in the B-47 Weapon Delivery Handhook may be verified or corrected. In addition, the pro- Jeet will provid> basic research data for the desimn criteria of future USA aircraft. INSTRIIMENT ATION Two hundred seventy three data channels were available on this shot to record bending shear and torsion in the wing and horizontal stabilizer, thermal inputs to the aircraft, thermally intucei strain, temperature measurements, and overpressure. YPrior to shot participation these channels were operating satisfactorily. 97.0% of There has been no newly aided instrumentation since the last perticiretion. ATRCRAFT POSITION IN SPACT The P-47 was flying at an absolute altitude of 34,000 feet, a speed of Mach 0.77, and on a heading of 270° at both T, and shock arrival, The aircraft was oriented tail to the shot; at T, the horizontal range beyond GZ was 33,000 fect, and at shock arrival it was approximately &6,0%0 feet o w ™ \ ' isn
