Abstract: Force measurement in a low speed wind tunnel was conducted to investigate the effects of the height of a distant canard wing on the longitudinal aerodynamic characteristics of a forward-swept configuration. The Reynolds number is about 1.44×10⁵ based on the average chord length of forward-swept main wings. The results indicate that it is more favorable for the lift characteristic to equip a lower canard wing away from a greater forward-swept main wing, and the canard wing below the main forward-swept wing also slows down the stalling of theconfiguration. Canard wing increases lift coefficient with the penalty of the increase of drag coefficient. The increase of drag coefficient is significant at higher angles of attack. An upper canard, which is in the vicinity height of forward-swept main wing, could improve the maximum lift-to-drag ratio. Much more increase of maximum lift-to-drag ratio can be obtained with a forward-swept main wing with a small sweepback angle leading edge.
