Summary:Drag is a significant contribution to the fuel consumed by an aircraft and is directly proportional to the carbon footprint of an aircraft. With net-zero carbon emission goals set by the International Air Transport Association, aircraft with efficient fuel usage is therefore desired [1]. Inspired by the success of plasmabased dielectric barrier discharge (DBD) actuators [2], which have recently demonstrated an ability to produce significant reduction in skin friction drag [3], [4], our group has initiated an in-depth study into both the plasma physics and aerodynamics of these plasma devices. By examining parameters such as the actuator array configuration (e.g. spanwise wavelength), as well as the choice of excitation waveform, our goal is to develop a plasma-based device that demonstrates both high energy efficiency and effectiveness in reducing skin friction drag, at both low and high Reynolds numbers.
