Abstract
A method and device are provided for manipulating high-speed flows without moving aerodynamic structures. More particularly, a flow control actuator device is provided that is capable of producing a pulsating synthetic jet with high exhaust velocities for manipulating high-speed flows without moving aerodynamic structures. The high exhaust velocities of the actuator device may reach sonic levels of Mach 1 or greater. In one embodiment, the device may be constructed as an array of devices. In such an embodiment, each individual device is preferably reduced to a very small size. In such an embodiment, each individual device can then be fired in temporal patterns to create high-speed synthetic jets of air extending above the surface of the each device.
