Abstract:
The 3 D incompressible N S equations with momentum source terms are solved to simulate the flow fields of coaxial rotor configurations. Induced velocity distributions of the coaxial rotors have been compared with that of a single rotor with the same geometry, advance ratio and pitch angle. The results reveal the aerodynamic interference between the upper and the lower rotors. The effects of distance between the rotors, root blade pitch angle, advance ratio, etc. are investigated.
Key words: r ot or aerodynamics, downwash, momentum source, coaxial rotor
