Abstract:

To augment the basic knowledge of the vulnerability and thermoelastic response operating in the vicinity of a nuclear detonation, various aircraft structural components were instrumented for time-history temperature and strain response and exposed to the thermal andor blast inputs during Shots 9 and 10. Specimens chosen were box beams, tension ties, stabilizer and elevator assemblies, and structurally bonded metal hat, waffle, and honeycomb core type aircraft panels. These stabilizers were preloaded to simulate an inflight condition and exposed in sets of three, such that one was shielded from blast, one shielded from thermal radiation, and the other un-shielded. Structurally bonded metal aircraft panels were also instrumented for peak skin temperature determination with temp-tapes and exposed to determine the threshold temperature for permanent skin buckling and for bond release. A B-36 stabilizer and elevator assembly and a B-36 wing outer panel were exposed and instrumented with temp-tapes to investigate local panel damage. Samples of fabric and foil control surface coverings were exposed to establish a threshold of thermal damage for each type of covering.
