Low frequency synthetic jet actuator and method of manufacturing thereof

A system and method for lowering the structural natural frequency of a synthetic jet actuator (50, 76, 82, 88, 96, 100) is disclosed. A synthetic jet actuator (50, 76, 82, 88, 96, 100) is provided that includes a first plate (52), a second plate (54) spaced apart from the first plate (52) and arrang...

Zusammenfassung:	A system and method for lowering the structural natural frequency of a synthetic jet actuator (50, 76, 82, 88, 96, 100) is disclosed. A synthetic jet actuator (50, 76, 82, 88, 96, 100) is provided that includes a first plate (52), a second plate (54) spaced apart from the first plate (52) and arranged parallelly thereto, and a spacer element (62, 78, 84, 90, 98, 102) configured to space the first plate (52) apart from the second plate (54) and define a chamber (64) along with the first and second plates (52, 54). The spacer element (62, 78, 84, 90, 98, 102) includes at least one orifice (66) formed therein such that the chamber (64) is in fluid communication with an environment external (68) to the chamber (64), and the spacer element (62, 78, 84, 90, 98, 102) is constructed to deform in a bending motion in response to a deflection of at least one of the first and second plates (52, 54).
