Patent ID: 7748664

Claim:
An apparatus for manipulating a primary fluid flow over a surface, the apparatus comprising: a surface adapted to receive a primary fluid flow; a first diaphragm and a second diaphragm; a sealed chamber embedded in the surface, the sealed chamber having at least one orifice, wherein the first diaphragm and the second diaphragm form outer walls of the sealed chamber; a first mechanical actuator coupled to the first diaphragm operable to deflect the first diaphragm; and a second mechanical actuator coupled to the second diaphragm operable to deflect the second diaphragm; and wherein: outward deflection of the first diaphragm and the second diaphragm cause the chamber to fill with fluid; and inward deflection of the first diaphragm and the second diaphragm cause the chamber to create a pulsed jet by expelling fluid through the orifice of the chamber to manipulate the primary fluid flow that is flowing over the surface.
