Flutter of infinitely long plates and shells -- 2

Aeroelastic stability of infinitely long, isotropic cylinder with outer surface exposed to inviscid flow is re-examined; cylinder behavior is described by shell equations of Goldenvieser, whereas aerodynamic forces are described by classical linearized potential theory; extensive numerical results for flutter velocity (and dynamic pressure) indicate effects of Mach number, thickness -- radius ratio, and density, or mass ratio; important consequence of present study is indication that aerodynamic loading on cylinder is of "slender body" type when axial wavelength is large compared to circumferential wavelength; it may be expected that similar result will hold for cylinders of finite length.
