Keywords: UCAV, high angle of attack, maneuverability, leading-edge vortex

Configuration studies of future Unmanned Combat Air Vehicle (UCAV), such as leading-edge shape, centerbody and wing platform, were conducted both experimentally and numerically. More than 50 configurations were investigated. Aerodynamic loads, surface pressure, and flow visualization data were collected. The range of the angle of attack was from where the leading-edge vortex is fully developed up to where the leading-edge vortex is totally broken down.
