Development of High Lift Devices for Application to Advanced Navy Aircraft

Abstract

A number of methods for generating high lift to provide a short takeoff and landing (STOL) capability for advanced Navy aircraft are evaluated, with emphasis on low aspect ratio wings. Upper surface blowing, circulation control wing, and wing tip sails are given the most attention. Experimental data are being obtained in the DTNSRDC wind tunnels on these concepts as specifically applied to wings of aspect ratios 3 to 5. Flight demonstrations by Grumman and DTNSRDC of a circulation control wing application to the A-6 aircraft have shown the ability to more than double the lifting capability which resulted in landing speed reductions of more than 30 percent, landing ground roll reductions of more than 50 percent, and takeoff distance reductions of at least 25 percent. The experimental high lift system data have been applied to a conceptual STOL baseline aircraft in order to estimate the impact on mission performance and identify their various merits as applicable to the particular restrictions of small ship operations.
