The effects of different canard's swept angles and jet momentum coefficients on the lift increment of simple close-coupled canard configurations with a 40-deg swept delta wing were investigated in a low-speed wind tunnel by force measurement. The experimental results show that at a certain range of attack angles (16-50 deg); on the condition of no blowing; with the increasing of the canard's swept angles; the lift increment and critical stall angles increase; which shows that the canard can be used as a controlling element for aerodynamic forces. On the condition of blowing; when the jet momentum coefficient exceeds a certain value; the more the jet momentum coefficient is; the more the lift increment is; which suggests that indirectly controlling the wing vortex is possible by canard-spanwise blowing for close-coupled canard configurations;
