Interaction of a blast wave with a highly sweptback wing model was measured in a series of two sled tests performed on the 50,788-foot tract at Holloman Air Force Base in June and August of 1977. These two tests were a continuation of the program of three tests carried out during the summer of 1976. The sled, traveling at Mach 0.76, was intercepted successively by blast waves produced from the sequential detonation of three charges of TNT. The model consisted of a sting-mounted wing and fuselage combination. Wing properties were: 46.80-in. span, 18.95-in. mean chord, 2.47 aspect ratio, 0.29 taper ratio, 67 deg. leading edge sweepback, 64.8 deg. quarter-chord sweepback, and a 64A012 wing section. Blast induced loadings were measured at 20 locations on the wing for blast intercept overpressures of about 4 psi for blast intercept angles of about 50, 90 and 135 degrees from head-on. In the first test blast intercepts from bursts 45 degrees out of the plane of airplane symmetry were simulated by mounting the model at a roll angle of 45 degrees. In the second test a 10,000 pound charge was employed for one burst for studying the effect of blast yield. This report describes the tests and presents the reduced test data. (Author)
