TURBULENT FLOW DRAG REDUCTION

摘要

The present invention relates to apparatus (3) for influencing fluid flow over a surface (1), and more particularly, but not exclusively, to turbulent boundary layer flow drag reduction for an aircraft. The present invention provides such apparatus including a plasma generator (7) comprising first (7) and second (9) spaced-apart independently controllable electrodes operable to cause a change in direction of the flow of the fluid over the surface.
