Holographic Displacement Measurements on a Highly Skewed Propeller Blade

摘要

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. The holographic displacement results were studied for favorable correlation with those from a finite element analysis.
