Abstract:
1. A synthetic jet actuator comprising: a sealed cavity located on the inside surface of an airfoil skin wherein the sealed cavity is incorporated in a rigid walled hollow chamber having an open end and a closed end, and attached at said open end to the inside surface of said airfoil skin, a flexible diaphragm extending across said rigid walled hollow chamber, engaging an intermediate circumference of an inner wall and located between said open and said closed end to seal the cavity, an orifice extending through the airfoil skin into the rigid walled hollow chamber, and a fluid contained within a second cavity formed between said closed end and said flexible diaphragm, wherein, upon excitation of said fluid in a sloshing mode, air is alternately entrained and expelled from the cavity formed between the flexible diaphragm and the inside surface of said airfoil skin.
