Two-dimensional views are presented of the first three natural vibration mode shapes of ten cantilever-wing models. A table of normalized deflection at six spanwise and five chordwise stations is included for each mde. These mode shapes were measured by a rather unique experimental technique using grains of sand as accelerometers. The technique, which is particularly-suited for measuring mode shapes of small wing models, is described and some of the difficulties likely to be encountered in applying the technique are discussed.
