7 Wi cosa 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. ~ 32 = S Gy Cee oe —_—
