An experimental parametric analysis has been completed for close-coupled canard effects on the transonic aerodynamics of a generalized wing-body aircraft configuration. The parameters investigated include wing sweep and position and deflection and planform of the canard for aircraft configurations with horizontal tail on and tail off. It was found that a 45-degree delta canard at approximately -5-degrees deflection, located above and forward of but slightly overlapping the wing, gave the best overall performance. A canard placed properly with respect to a 50-degree sweep wing resulted in aerodynamic performance suitable for a highly maneuverable fighter. Further, a close-coupled canard used with the 25-degree sweep wing resulted in aerodynamic performance desirable for attack/bomber missions. In addition, it was found that a properly placed canard was useful in alleviating aircraft buffet, particularly on the wing with the 50-degree leading edge sweep. (Author)
