title = "On the Use of Discrete Jets for Control of Moments on Tailless Aircraft",
abstract = "The broad practical purpose of this study was to explore the effectiveness of Active Flow Control (AFC) in controlling a tailless aircraft model called the SWIFT that was designed in the UK under the auspices of NATO{\textquoteright}s Advanced Vehicle Technology program. Wind tunnel tests focused on the maintenance of trim at high lift coefficients using a single supersonic jet emanating from a small nozzle at an appropriate location and orientation relative to the free stream. Although none of the AFC parameters was properly optimized the trimmed lift coefficient was tripled. To understand the effect of AFC on the flow over such a wing, flow visualization and Particle Image Velocimetry (PIV) were used. Proper Orthogonal Decomposition applied to this data revealed unsteady behavior in the vortex lift-off and its advection over the outer wing that was effectively subdued by AFC thus extending the range of incidence angles that could be flown. Preliminary tests were carried out on yawing and rolling moments exploring the possibility of replacing conventional control surfaces on an airplane by AFC. Wind tunnel data were acquired at Reynolds number of 1.6x106 based on the root chord of the semi-span model used.",
