A thin elastic shell under tension is wrapped around a rigid curved surface; the latter renders the stiffness of the shell effectively nonlinear. Examples of such a configuration in practice include the NASA Skylab Space Project and certain submarine geometries. The static aeroelastic stability of the shell is examined for a subsonic flow along the axis of the shell and the longitudinal axis of the curved rigid surface. The minimum flow velocity for which the elastic shell will deform statically (buckle) is determined, as well as the amplitude of the deformation as a function of flow velocity
