Patent ID: 7988103

Claim:
A flow control actuator device constructed of an inorganic ceramic insulator for creating a pulsating synthetic jet stream capable of causing a macro-scale flow effect, the device comprising: a body; a cavity respectively defined in the body and having a cylindrical orifice comprising a converging-diverging nozzle to enhance a flow characteristic of air entering and being discharged from said cavity respectively defined in a outer facing sidewall of said cavity to allow air to enter said cavity at a normal pressure and be discharged from said cavity at a supersonic velocity as a synthetic jet stream to cause said macro-scale flow effect, wherein said air is cyclically discharged from said cavity at said supersonic velocity in response to initiation means for repetitively initiating said electrical discharge within said cavity, said initiation means initiates said electrical discharge simultaneously within at least two or more devices within said array, said initiation means comprises a power circuit coupled to at least three electrodes, said power circuit for establishing a voltage potential sufficient to create said electrical current discharge between said at least three electrodes.
