Abstract:

An investigation of the effect of a close-coupled canard on the aerodynamic characteristics of a 0.10-scale F-4B aircraft has been conducted in the NSRDC 8 x 10-foot subsonic wind tunnel. The model was pitched through an angle of attack range from -3 to 30 degrees. The canard was positioned at three vertical positions at one longitudinal station both with and without horizontal tail. The addition of the canard produced two important results a 30 percent increase in lift coefficient and an increase in useable angle of attack of 6 degrees. Author
