Abstract

The air flow past a wind tunnel model of an Eurocopter BO-105 fuselage, main rotor and tail rotor configuration is simulated by solving the time dependent Navier-Stokes equations. The flow solver uses overlapping, block structured grids to discretize the computational domain. The simulation setup and the execution on a parallel NEC-SX8 vector computer are described. The numerical results are compared with unsteady pressure measurements on the fuselage and the blades. An overall good agreement is found. %Differences between predicted and measured data on the main rotor and the tail rotor can be explained by blade elasticity effects. The high computational effort is highlighted.
