摘要: First results obtained by French and German Research Centers towards the CFD computation of complete helicopter are reported. Improvements methods described: Methods to improve capture vortices, preconditioning techniques for improved efficiency accuracy at low velocities, improvements Chimera grid technique, experiences with strong fluid structure coupling. Results steady viscous flows around isolated rotors in hover fuselages presented.
