On the Use of Power-Based Parameters for Blowing Active Flow Control Systems

What is it about?

Active flow control uses tiny jets of air to change the flow around an aircraft. Researchers in the field have traditionally treated jet strength as the most important parameter. We challenge this practice because integrating active flow control technologies into aircraft design requires much more than understanding the relationship between jet strength and aerodynamic benefits gained. Our experiments show that control efficacy is a complex function of many independent parameters such as wing shape and jet location.
