ABSTRACT	Wind tunnel tests were conducted to investigate the fundamental flutter characteristics of a tip-fin configuration wing.Two types of models were tested to provide experimental data for the flutter analysis of non-coplanar wings.One is a normally plain wing and the other has a cant angle of 15°at the tip-fin.They were tested in the 2m×2m low-speed wind tunnel.On the tip-fin wing,mild flutter with limited amplitudes was observed in a certain in flutter prevention.Model tests on the models were performed automatically using the Dynamic Displacement Measurement System.
