“…The substantial advantages of the closed‐couple canards were investigated by Behrbohm1 in 1965 and found that maximum lift coefficient can be obtained with high stall angle. [ 1 ] The effects of short, coupled canards and effects of varying planform have been studied extensively by US Navy and NASA to find practicable solutions to use in warships and aircrafts. [ 2–5 ] The controlling capability of the canard configuration was investigated and compared with the conventional horizontal tail configuration.…”

The present study investigates the flow behavior due to three different vertical canard locations on the scaled‐down model aircraft by using tuft flow visualization and boundary layer measurements. The aircraft is fabricated with wing airfoil S1223 modified and canard with N22 airfoil using laser cutting technique. Three different color tufts are pasted in wing and canard at 30%, 60%, and 90%. The assembled model is placed inside the subsonic wind tunnel with flow chord Reynolds number 3.8*106, which corresponds to 35 m s−1 of the flow velocity and zero‐degree angle of attack. The boundary layers are measured at 70% of the wing chord with 00 incidence angle at three different span locations, i.e., 30%, 60%, and 90% of the wingspan with varying vertical canard positions. The results are compared with wing alone and it is found that the high wing and high canard configuration are outperformed by providing minimum velocity gradient and hence minimum skin friction drag. The tuft flow visualization also shows the identical results as the boundary layer measurements results. The aerodynamic performance of the high wing high canard configuration is found to be promising, as the skin friction drag coefficient is found to be minimum.
