Sweeping jet actuators

Sweeping jet actuators are a type of active flow control technology based on fluidic oscillators used to produce sweeping jets. The first use of fluidic oscillators in the form of sweeping jets for flow control was demonstrated by Raman et al., 1999. and later by several authors working in the area of flow control. Many organizations have been working on the use of such actuators for flow control. Boeing, NASA and the University of Arizona Department of Aerospace and Mechanical Engineering, Illinois Institute of Technology, [Advanced Fluidics], Technical University of Berlin are a few of them. They are slots built into the control surface of an airfoil that build on the same principles as that of blown flaps; that by actively blowing air over the surface of an airfoil the effective lift produced by it is increased. (Wikipedia).

In this video the flaps have 90 degrees rotation freedom and an airfoil shape. These allows flaps act like car spoilers which gives extra push to sail toward the wind which increases the efficiency of the turbine. Notice that even with one sail it moves toward the ventilator which acts as
