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.
The invention claimed is: 1. Apparatus for influencing boundary layer fluid flow over a surface, the apparatus including a plasma generator comprising: a first electrode, said first electrode comprising first and second elongate elements; and a signal generator for driving the first electrode with a pulsed signal and for causing said fluid to move in a direction from one of said elongate elements to the other of said elongate elements, wherein said first elongate element receives a first pulse and the second elongate element receives a second pulse afte...
