A grid generator system for the modelling of complex multi-bladed rotors is under development in Europe as a part of the development of a complete rotocraft simulation method: the Brite/EuRam EROS project. The grid generator (1) exploits a CHIMERA domain decomposition on structured grids. The development is being carried out by a rotorcraft manufacturers (Augusta, ECD, GKN-Westland), research centers (CIRA, DERA, DLR, NLR, ONERA), and Unversities (Polit. Milano, Univ. Glasgow, Univ. Rome 3). It addresses the industrial need for a rotor aerodynamic prediction tool (2) able to capture rotational phenomena, such as blade tip and wake vortices, and to predict correctly the unsteady blade pressures over a range of flight conditions, from hover to high-speed forward flight. This paper presents and discusses the capabilities of the GEROS grid generator together with relevant results.
