Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NONUFM, volume 72) Summary This work describes the advancements in developing a computational method for the treatment of solid fluid interaction (SOFIA) to analyze and to improve the aerodynamic performance of elastic wings and rotors by direct numerical aeroelastic by: 3. Numerical features of a quasi-3D and a 3D Navier-Stokes unsteady aeroelastic solver are discussed: turbulence models, grid deformation techniques, specific boundary conditions, dual time stepping. The chapter presents the necessary steps in setting up a numerical simulation model of the ACFA blended wing body design. After a short introduction, a section on structural modeling presents.

The CFD analysis accounts for the elastic deformations using a dynamically deform-ing mesh system. All the rotor blades are assumed to be identical, therefore to reduce the computational.
