| Abstract: | The rigid-wake mode of co-axial rotor in forward flight was set up based on analysis of infinite blade rigid-wake mode. The method of aerodynamic characteristics of co-axial rotor in forward flight was studied by given rotor geom etry, distance between upper and lower rotor, advance ratio. The example of the method indicates that the theoretical and experimental results are consistent well. |
