This report documents the results of an experimental program to study the phenomenon of chordwise bending flutter. An extensive series of vibration bench tests, using both prototype blades and the actual J-blade hardware, resulted in the choice of the first bending mode of a fully double-cantilevered configuration as the chordwise bending mode to be tested. Alterations in both method of blade attachment and in the blade geometry itself were introduced to improve the desired mode shape and frequency. The vibration bench tests were carried out in conjunction with NASTRAN predictions and supersonic cascade aerodynamic computations. Comparisons between theory and experiment are discussed.
