Summary

Low-speed windtunnel experiments have been carried out on canard-wing-body configurations with two fuselages (flat and round), two delta wings (AW = 2.31 and 1.38) and two canards (AC = 2.31 and 1.65). The canard’s position relative to the wing-body combination has been varied systematically. The interference of the vortex systems generated by canard, wing and fuselage has been studied by means of six-component-, pressure-distribution- and flowfield-measurements as well as by flow visualizations.

The canard configurations reach higher maximum lift coefficients than the wing-body combinations. At the wing vortex formation is suppressed in the region of the apex and amplified in the tip region. The trailing vortex sheet of the canard merges with the suction side boundary layer of the wing. The interference between canard and wing depends strongly on the height of the canard’s trailing-edge above the wing. With increasing setting angle of the canard the tendency towards merging of the vortex systems from canard and wing is increased. In unsymmetrical flow sudden changes of the force and moment coefficients occur due to different vortex interference on both sides and due to a collapse of vortical flow on the windward side of the configuration.
