Comparative Stress/Deflection Analyses of a Thick-Shell Composite Propeller Blade

Abstract

To assist propeller designers in developing blade designs based on composite structures, an overview of composite material characteristics and available structural analysis methods was undertaken. Using detailed analyses of a thick-shell composite and a solid bronze blade, it was shown that three- dimensional finite-element analysis is useful for predicting relevant stresses and deflections. A more simplified approach was not satisfactory. To establish the feasibility of composite blades, further information about acceptable stress and deflection levels is needed.
