The Euler equations are used to compute steady and unsteady three-dimensional transonic flows around nonlifting rotor blades. A hybrid numerical procedure is used that treats the spanwise derivatives explicitly and the other spatial derivatives implicity. The steady state results are in excellent agreement with results obtained from the full potential equation. The results for unsteady flow compare well with measurements. These results demonstrate the ability of the Euler solver to compute transonic flow around helicopter blades.
