Abstract
An aerodynamic or hydrodynamic surface having a swept-back leading edge includes at least one flow separation device located on an attachment line of the leading edge, such as a step-up, step-down, fence or gap. The flow separation devices are preferably arranged normal to the leading edge and are dimensioned so that span-wise turbulent air flow is re-laminarized downstream of the devices thus reducing skin-friction and greatly improving the aerodynamic or hydrodynamic efficiency of the surface.
