Flutter of infinitely long plates and shells. II - Cylindrical shell
The aeroelastic stability of an infinitely long, isotropic cylinder with the outer surface exposed to an inviscid flow is re-examined. The cylinder behavior is described by the shell equations of Goldenvieser, whereas the aerodynamic forces are described by the classical linearized potential theory. Rather extensive numerical results for flutter velocity (and dynamic pressure) indicate the effects of Mach number, thickness1-radius ratio, and density, or mass ratio. An important consequence of the present study is the indication that the aerodynamic loading on the cylinder is of the "slender body" type when the axial wavelength is large compared to the circumferential wavelength. It may be expected that a similar result will hold for cylinders of finite length. © 1966 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
