Low Speed Characteristics Study of Various Supersonic Airfoils Using Co-Flow Jet Active Flow Control
, 2023 This paper studies the lift enhancement effect of Co-Flow Jet (CFJ) at takeoff condition for three thin airfoils at free-stream Mach numbers of 0.1, 0.2 and 0.3. Parametric studies are conducted to investigate the effect of the jet momentum coefficients (
