Abstract
A 'control'vortex concept for generating high-alpha yaw and pitch control on low-observables type forebodies (viz., having diamond-shpaed chined cross sections), is proposed for exploratory low-speed wind tunnel study. Two parallel approaches for realizing the control concept will be evaluated on a generic forebody configuration: a mechanically actuated vortex flap and a novel slot-blowing technique. Six-component force/moment data will be acquired with emphasis on the high-alpha regime and including large side-slip angles, to identify key variables governing the efficacy of the two techniques; complimentary flow visualizations will also be performed.
