An unstructured rotating mesh methodology is developed for the Euler flow computation over rotor blades. A two-zone unstructured mesh is set up with one rotating zone encompassing the blade and one stationary zone extending to the far stream. The rotating zone rotates rigidly with the blade and slides against the stationary zone. The sliding zonal interface is specially designed to enforce the flux conservation between the two zones. The Euler equations are solved in the inertial frame for both zones. The flowfield of a helicopter blade in hover and in forward flight are computed to validate the present methodology.
