The low-speed aerodynamic characteristics of a 10-percent scale powered SCAT (Surveillance, Communications, ASMD Warning, and Targeting) configuration were investigated in the 8- by 10-foot subsonic north wind tunnel. Force and moment data were obtained for both powered and unpowered VTOL, fixed-wing aircraft. Analysis of the data indicate that the configuration is statically stable in both pitch and yaw and that control is adequate for both axes. The addition of a large aft-mounted radome did not significantly change longitudinal characteristics, but did increase lateral-directional stability. Two wings of different airfoil sections were evaluated: a NACA design and a Liebeck design. The Liebeck wing section increased lift over that generated by the NACA baseline wing section. (Author)
