초록

The present invention relates to apparatus for influencing fluid flow over a surface, 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 comprising a first electrode and a signal generator, the apparatus being operable to drive the first electrode with a pulsed signal generated by the signal generator thereby to cause a change in direction of the flow of the fluid over the surface.
