This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...
The analysis of a member carrying a combination of lateral and axial
loads (a "beam-column") is a problem of frequent occurrence in aircraft
structural design. This thesis presents the derivation and application
of the Polar method, both analytical and graphical. The method was first
suggested in Germany, several years later...
