Abstract
A high bandwidth multi-stage microjet actuator. The actuator can produce relatively large amplitude flow disturbances over a broad range of frequencies. The disturbance frequency can be varied by altering the geometry of the device, altering the pressure ratio(s) within the device, and combinations of the two. The actuator has many potential applications, including noise abatement for jet aircraft, and flow control over a moving airfoil.
