        Abstract
        A wind-tunnel study to find the lift and drag characteristics of a low-aspect-ratio wingbody configuration from an angle of attack (AOA) of -8 to 50 degrees was conducted. A further study to find the comparative lift enhancement using the same wingbody with a close-coupled canard for wingbody angles of attack of 10, 22, 34, 40, and 48 degrees and canard deflection angles from -25 to 25 degrees was carried out. It was found that a properly-located canard enhanced the lift at all tested angles of attack, compared to the baseline wingbody configuration results. The lift enhancement was maximized in the post-stall regimes, reaching values up to 34%. A small improvement in lift- to-drag ratio was noted at all tested angles above 10 degrees angle of attack.

          Close-coupled oscillating canard effects on post-stall lift enhancement 

          McBane, Douglas G. (Monterey, California. Naval Postgraduate School, 1993-06);
          The effects of an oscillating close-coupled canard on the canard/wing vortex interaction for increased lift enhancement were studied. Two test conditions were studied: the first with a model angle of attack of 22 deg. and ...

          Lift enhancement using a close-coupled oscillating canard. 

          Schmidt, Dean Christopher (Monterey, California. Naval Postgraduate School, 1992-09);
          A wind-tunnel study to investigate the effects of dynamic stall of a closecoupled canard on the canard/wing vortex interaction for increased lift enhancement was conducted. Two angles of attack of the model were studied: one ...

          Flowfield study of a close-coupled canard configuration 

          O'Leary, John F. (Monterey, California. Naval Postgraduate School, 1992-06);
          A nulling five-hole pressure probe was used to complete a flowfield survey behind a close-coupled canard and wing model set a 32 degrees angle of attack. The canard and wing were both low-aspect-ratio, highly swept, delta ...
