Flow Modulation and Fluid—Structure Interaction at Airplane Wings

Part of the book series: Notes on Numerical Fluid Mechanics and Multidisciplinary Design ((NNFM,volume 84))

Summary

A beam model for the idealization of airplane wings for numerical studies in aeroelasticity is presented. The structural model gives a good approximation of the static and dynamic (eigenfrequencies) wing behaviour. It is to be implemented in the routines of computational aeroelasticity within the framework of this Collaborative Research Center. It extends the Timoshenko beam by incorporation of additional effects, such as taper, restrained warping and the effect of ribs and considers different material properties within the wing cross section. Examples are presented which demonstrate the influence of the additional effects on the static and dynamic behaviour of the wing. The reduced structural wing model yields results that are in good agreement with finite—element calculations and provides a suitable tool for sensitivity analyses.
