The response of test structures and structure elements to sonic booms produced by XB-70, B-58 and F-104 aircraft was studied. These aircraft produced sonic booms of different signature durations. They were flown at several flight track offsets, altitudes and Mach numbers so as to generate different overpressure levels and signature characteristics. Free field signature data and the effects of free field signature parameters on structural response were analysed. Studies were made of the plate response lateral deformation and racking response in-plane deformation of the test structures. Damage complaints resulting from the test missions were investigated and the results analysed. The implications of the magnitudes of the responses of the test structures and the investigation of the damage claims resulting from the test missions on possible damage caused by supersonic flights were discussed.
