Interaction of a blast wave with a 35 deg-sweepback wing model was measured in a series of two sled tests performed on the 50,788-ft sled tract at Holloman AFB in September 1979. The model was rigid and had a 5.6 aspect ratio and 0.42 taper ratio. The sled, travelling at Mach 0.76, was intercepted successively by blast waves produced from TNT charges. Blast-induced pressure differentials were measured at 20 locations on the wing. Shock overpressures ranged from 1.3 to 4.1 psi and intercept angles were 45, 90 and 135 degrees from head-on. This report describes the tests and presents the test results. Preliminary analysis of the test results indicates the existence of non-linear blast-induced airloads on the model at the lowest shock overpressure. (Author)
