HOLOGRAPHIC DISPLACEMENT MEASUREMENTS ON A HIGHLY SKEWED PROPELLER BLADE

Static deflections were measured on a highly skewed marine propeller blade model using holographic interferometry. A specially designed pressure chamber was used to load the blade model under uniform air pressure from one side. The method that was used to predict the three-dimensional displacements from the holographic fringes is developed and described in the appendix. The holographic displacement results indicated a favorable correlation with those from a finite element analysis. It was found that the deflection response of this blade cannot be adequately predicted by the conventional method using cantilever idealization.
