Contributor Van Tooren, M.J.L. (promotor) Faculty Aerospace Engineering Department FPP Date 2012-02-03 Abstract This thesis introduces a new parameterization technique based on the Class-Shape-Transformation (CST) method. The new technique consists of an extension to the CST method in the form of a refinement function based on B-splines. This Class-Shape-Refinement-Transformation (CSRT) method has the same advantages as the original CST method, while also allowing for local deformations in a shape. A number of test cases were performed using two different design frameworks with low and high fidelity. The low fidelity framework was based on a commercial panel method code and coupled to various optimization algorithms. The high fidelity framework used an in-house Euler code and employed adjoint optimization.
