Recent advances in morphing, simulation, and optimization technologies have enabled analytically driven aerodynamic shape optimization to become a reality. This paper will discuss the integration of these technologies into a single process which enables the aerodynamicist to optimize vehicle shape as well as gain a much deeper understanding of the design space around a given exterior theme.

A measure of functional degradation or its surrogate is more informative than attribute data such as failure time when improving designs or developing meaningful tests. This paper delineates the advantages and disadvantages of using degradation data, and the situations under which one should or should not use degradation analysis. A comparison has been done between degradation testing, testing to failure, and bogey testing. The steps necessary to apply degradation analysis techniques to product design have been described: determine scope of the project, plan degradation test, collect data, analyze data, and document results. A case study has been used to demonstrate the whole process of degradation analysis techniques.
