Popis: This chapter presents a fully coupled 2D fluid–structure interaction (FSI) simulation of PZL W3 Sokol main rotor blade. Loosely coupled simulation is performed using ANSYS Fluent and MSC Nastran solvers in separate domains with a custom coupling tool developed at PZL Swidnik for load transfer between the domains. A computational fluid dynamics (CFD) mesh deformation interpolation method based upon Nastran structural solver is proposed. By variation of the interpolator parameters, high quality of the deformed mesh can be achieved with controlled level of cell distortion. Such mesh deformation approach is quite easy to implement and computationally effective yet allowing for robust distortions transfer for a wide range of blade rigid body motions as well as surface deformation with minor fluid mesh quality degradation.
