Abstract

A comprehensive technique, based on a higher-order laminate theory is developed for the analysis of the thick composite load-carrying section, modeled as box beams, in the blade. The theory is a three-dimensional model which approximates the elasticity solution so that the beam cross-sectional properties are not reduced to one-dimensional beam parameters. The Kreisselmeier-Steinhauser function is used to formulate the multiobject function problem. The search direction is determined by Broyden-Fletcher-Goldfarb-Shanno algorithm. The results were compared with the baseline values and show significant improvements in the overall performance of the tilt rotor blade.
