Abstract
The effective aspect ratio of the wing of a freeflight model, with and without end plates, were obtained by measuring the flight velocity and the inclination of flight path. Investigation was also made for a wing with a leading-edge slat. The flow patterns around the wing tips were presented which were photographed in a smoke wind tunnel. The profile of the end plates was of the NACA 6420 wing section. The increaments in the effective aspect ratio were about 3.5 and 2.5 times those of the rectangular wings, the areas of which were increased by the area of end plates at the wing tips of the basic wing, for the cases without and with a slat, respectively.
