The solution for the induced flow of a rotor in axial flow has a long history of interest going back to Prandtl and Goldstein. The nominal inflow is computed in a rather straightforward manner for an infinite number of blades, but complicated root and tip corrections appear when there are a finite number of blades. Prandtl worked out an elegant, yet simple approximation for the tip correction that still has widespread applications. The purpose of this paper is to provide a similar root correction for the induced flow of rotors with a finite number of blades. Several alternative versions of the correction are provided, ranging from a simple computation in the spirit of Prandtl to a virtually exact numerical solution.
