- This paper presents a combination of a computational structural dynamics (CSD) and high fidelity computational fluid dynamics (CFD) analysis which is based on overset structured grid. Regarding a helicopter rotor in hover, aerodynamic loads are computed from the threedimensional Euler/Navier-Stokes solver in overlapped grids, and blade motions are estimated from the geometrically exact rotor beam analysis. While combining those two analyses, a loosely coupled method is used and the results are validated regarding a civil transport helicopter.
