  3. Abstract:
  4. A series of wind tunnel tests were performed to study the effects of a canard and its position on the downstream flowfield over the wing surface. The wing surface pressure was measured for both canard-off and canard-on configurations. In addition, the canard position effects on the wing were investigated at different angles of attack. The canard was installed at three vertical positions and at two different horizontal distances from the wing apex. The results show a remarkable increase in the wing suction peak for the canard-on configurations. At low to moderate angles of attack, among the various configurations examined in the present experiments, the mid-canard configuration developed a higher suction on the wing while, at high angles of attack, the upper-canard was found to induce the most favorable flow field on the wing. In addition, higher suctions were achieved on the wing at moderate to high angles of attack, as the wing-canard distance was increased
