Abstract
D ESPITE aerodynamic advantages, aeroelastic complications have precluded the wide-scale adoption of the forward swept wing planform [1]. Forward swept wings may demonstrate liftdependent drag benefits due to spanwise load distributions that are closer to elliptic then an equivalent aft swept wing [2]. Fuselageinduced spanwise flow is also beneficial for forward swept wings; it reduces the effective sweep, whereas the opposite is true for aft swept wings [3]. The most apparent benefit of the forward sweep configuration is in lateral control; spanwise flow toward the root delays flow separation over the ailerons, whereas the opposite is true for aft swept wings [4]. Little information is available on the effect of highly swept wingswith forward sweepwhere flow separation is enforced. Consequently, an investigation has been undertaken using a 65 deg sweep arrow wing with fore and aft extensions.
