DYNAMIC AEROTHERMOELASTIC INSTABILITIES OF INFLATABLE VEHICLES AT HYPERSONIC SPEEDS.
Abstract
Analytical studies and experimental verification of the vibration and flutter characteristics of inflatable structures were accomplished as a first step toward establishing design criteria which will insure that lifting surfaces for future inflatable vehicles will be free from dynamic instabilities. The research effort was mainly confined to the Airmat-type structure, where the spacing of the surfaces is achieved by chords held in tension by internal air pressure. The principal Mach numbers covered were M = 8 and 10 with some tests at M = 4 and 6 to tie the results in with the previous investigation carried out for lower Mach numbers (M<6). (Author)
