Experimental investigation on longitudinal aerodynamic characteristics of Canard-Forward-Swept wing configuration

FSW (Forward-Swept-Wing) configuration is one of preponderant conceptions in the design of future generation fighter aircraft. The authors investigated experimentally the effect of canard wing and sweep angle on longitudinal aerodynamic characteristics of canard-forward-swept wing configuration by means of forces measurement in wind tunnel. The results indicate that the lift characteristics of FSW outweigh that of backswept wing at high angle of attack; FSW has higher stalling angle and keeps higher lift coefficient in a broader range of angle of attack near stalling angle, which is improved by canard wing located farther away from the main wing. A coupled canard wing can increase the lift coefficient of overall configuration. Meanwhile Canard-forward-swept wing has an excellent maneuverability.
