Note (General): In the present study, the basic effects of so called, “aeroelastic tailoring” on the flutter velocity are investigated. Six different models of high-aspect-ratio swept back wings were designed. The models consisted of composite plate-spars and wing sections of balse-wood. The dominant lamination angle of each spar was changed in a parametric manner. A vibration test was performed for each model. The frequencies and the vibration modes were measured to check the variations of the vibration characteristics due to differences of the laminate angle of the spars. The flutter tests were conducted in a low-speed wind tunnel and the hard flutter points were found for all models. It was shown that the flutter velocity of a model which has the wash-in type of the first bending mode is larger by 50％ than that of a model of which the first bending mode is the wash-out type.
