Abstract:

The flutter of two-dimensional panels of finite and infinite length on multiple simple supports in the streamwise direction was investigated theoretically under the assumptions that the system is adequately described by classical small deflection plate theory and quasi-steady, supersonic aerodynamic theory. No further physical andor mathematical approximations are made and a solution is effected by the method employed by Hedgepeth, Houbolt, and Movchan for the one bay two supports configuration. Specific numerical results are obtained for the one, two, three, four, five and six bay cases as well as the infinite bay case with motion of arbitrary spatial periodicity. Author
