Results from an ongoing supersonically-biased fighter wing-design study are summarized. The study has been conducted to explore the effects of supersonic aerodynamic performance, transonic maneuvering, low-speed/high angle-of-attack characteristics, and airframe system integration requirements on fighter aircraft wing design. The approach adopted involves the theoretical and experimental investigation of four advanced aircraft configurations which differ only in wing geometry. Supersonic and low-speed/high angle-of-attack wind tunnel results have been obtained for 20 deg trapezoidal, 65 deg delta, 70/30-deg advanced cranked, and 70/66-deg advanced cranked wing configurations. The supersonic data show that the advanced cranked wings outperform the trapezoidal and delta wings at cruise and moderate lift conditions. Low-speed/high angle-of-attack results show that all wings have significant stability problems above an angle of attack of 20 deg. Aircraft sizing analysis results show that the advanced cranked-wing configurations are significantly lighter, based upon take-off gross weight, than either the trapezoidal or the delta wings.
