Reports Summarize Aerospace Research Findings from RWTH Aachen University (Three-Dimensional Large-Scale Aerodynamic Shape Optimization Based on Shape Calculus)

By a News Reporter-Staff News Editor at Defense & Aerospace Week -- Investigators publish new report on Aerospace Research. According to news reporting out of Aachen, Germany, by VerticalNews editors, research stated, "Large-scale three-dimensional aerodynamic shape optimization based on the compressible Euler equations is considered."

Our news journalists obtained a quote from the research from RWTH Aachen University, "Shape calculus is used to derive an exact surface formulation of the gradients, enabling the computation of shape gradient information for each surface mesh node without having to calculate further mesh sensitivities. Special attention is paid to the applicability to large-scale three dimensional problems like the optimization of an Onera M6 wing or a complete blended-wing body aircraft."

According to the news editors, the research concluded: "The actual optimization is conducted in a one-shot fashion, in which the tangential Laplace operator is used as a Hessian approximation, thereby also preserving the regularity of the shape."
