Summary of Flow Modulation and Fluid-Structure Interaction Findings

The Collaborative Research Center SFB 401: Flow Modulation and Fluid-StructureInteraction at Airplane Wings investigates numerically and experimentally fundamentalproblems of very high capacity aircraft having large elastic wings. This issue summarizesthe findings of the 12-year research program at RWTH Aachen University whichwas funded by the Deutsche Forschungsgemeinschaft (DFG) from 1997 through2008. The research program covered the following three main topics of large transportaircraft: (i) Model flow, wakes, and vortices of airplanes in high-lift-configuration,(ii) Numerical tools for large scale adaptive flow simulation based on multiscaleanalysis and a parametric mapping concept for grid generation, and (iii) Validatedcomputational design tools based on direct aeroelastic simulation with reducedstructural models.
