Geodesic Wing Structural Optimization and Dynamic Analysis

Abstract

This report summarizes the construction of finite element models, validation of honeycomb finite element models, and preparation of a task road map for the future work. Finite element models were constructed based on two planform shapes. One is the planform of the intermediate complexity wing (ICW) model and the other is a rectangular (including square) planform. Two types of finite element models were generated in each planform: one has a honeycomb core with face sheets on top and bottom which are connected by rod elements while the other is a full-depth model, consisting of plates only. The finite element models of the honeycomb sandwich structures were compared to results from Hexcel Company verification models and to an actual test result. The road map for the task includes all the procedures necessary to perform the task efficiently, starting with model construction and validation of analytical predictions.
