Lecture: Advancing Active Flow Control Technologies for More Efficient Aircraft

Active control of air flow over aircraft wings can significantly improve aerodynamic performance. Pulsed jet actuation is a particularly promising technology – compared to steady jet injection, it can suppress flow separation much more effectively with reduced mass flow. Outcomes from the Clean Sky 2 WINGPULSE project will be presented, which was aimed at demonstrating pulsed jet actuator concepts for flow separation control that exceed the state-of-the-art – namely, those that reduce the net mass flow by a factor of at least 3. Results from wind tunnel testing and high-fidelity simulations will be described.
