Abstract
An actuator configured to rapidly vary the throat geometry of a microjet nozzle. Varying the throat geometry rapidly changes the characteristics of the microjet produced by the microjet nozzle. The inventive device is capable of producing pulsed flow. In some embodiments it is also capable of producing rapidly variable flow in order to provide active control.
