The present invention is directed to the manufacture of and the use of an aerodynamic flow control device having a compact array of a plurality of fluidic actuators in planar, curved, circular and annular configurations. The compact array of fluidic actuators of the invention may be designed to produce oscillating or pulsed jets at the exit ports with frequencies in the range of 1-22 kHz. They may be integrally manufactured along with the wing sections, flaps, tail and rudder of airplane, the inlet or exit geometries of a jet engine. When supplied with a...


1. An aerodynamic flow control device comprising a compact arrangement of an array of a plurality of discrete fluidic actuators having non-interconnected feedback channels located on a substrate wherein each of said plurality of said fluidic actuators comprises an input port and an exit port wherein each of said actuators is capable of producing at said exit port an oscillating or sweeping jet either in-plane or perpendicular to the plane of the fluid flow inside said actuator further comprising a common extension chamber extending from the exit ports of...
