Buckling Optimization of Variable Angle Tow Panels Using Exact Strip Models

A minimum-weight optimization strategy for Variable Angle Tow (VAT) panels subject to buckling and manufacture constraints is presented. The optimization is performed using a fast-running optimization package which employs exact strip analysis for buckling and a gradient-based optimization method. A new VAT panel manufacturing method providing good quality, Continuous Tow Shearing (CTS), is considered in the optimization strategy, where variable...
