Abstract
Apparatus and methods provide for a flow control actuator having a fluid cavity that is shaped to create periodic waveforms within the resulting resonant actuating flow with predetermined characteristics for actuating a high-speed fluid flow. According to various embodiments, a flow control actuator includes a power source for exciting the actuator fluid at a resonant frequency and a cavity shaped according to resonant macrosonic synthesis principles to maximize the exit velocity of the actuating flow at an orifice of the actuator.
