| Abstract: | The 3 D incompressible N S equations with momentum source terms are solved to simulate the flow fields of tandem and side by side twin rotor configurations. Induced velocity distributions on rotor plane, aerodynamic properties and general flow fields of twin rotor configurations have been compared with those of single rotors, and the results reveal the aerodynamic interference between two rotors of the twin rotor. |

| Keywords: | twin rotor rotor flow field rotor performance N S equations with momentum source terms |
