Example active flow control systems and methods for aircraft are described herein. An example method includes supplying pressurized air to a plurality of nozzles. The nozzles arranged in an array across a control surface of an aircraft, and the nozzles are oriented to eject the pressurized air ...
Active flow control methods have been widely studied for more than a decade in order to improve the airfoil's efficiency. This study is focused on fluidic actuation (the addition or subtraction of momentum to/from the boundary layer by blowing and/or sucking fluid). A synthetic jet is a ver...

Because of the nature of active flow control, simulation of this class of problems typically cannot be carried out accurately by methods less sophisticated than LES. Active control flowfields are highly unsteady, and can be characterized by small-scale fluid structures which are produced by the ...

A brief report on investigations into active methods for reducing the magnitude of the vibrational power flow associated with the propagation of flexural waves in elastic structures. Results are presented of experiments undertaken on a laboratory rig incorporating a uniform, thin steel beam. The power...
Acoustic cloaking of an elastic structure in a moving fluid using active control methods has been presented. The vibro-acoustic responses of an elastic cylindrical shell in potential flow under plane wave, monopole source and radial point force excitation were derived using Taylor's transformations and...
