This project was established to measure overpressure, gust, and thermal effects on a B-47E aircraft in flight and to provide additional research information on the effects of nuclear explosions on the aircraft. A B-47E aircraft was instrumented for measurement of overpressures, irradiance, radiant exposure, and of bending, shear, and torsion in the wing and stabilizer. Further instrumentation was made to measure thermal strain and the effect of high thermal inputs upon thin skins and supporting structures. Instrumentation was also installed to obtain bending, shear, and torsion responses of the fuselage when subjected to combined side and vertical loading. The general positioning criteria for the aircraft were wing bending up to 95% of design limit and/or a temperature rise of 600 to +700F in the thin-skinned elevator and aileron. In order to attain high temperature rises on participations in which the aircraft was gust critical, it was necessary to paint the thin-skin surfaces with high absorptivity paint. The data obtained in these tests were to be used in the design of future USAF aircraft.
