To establish a method for the calculations in the field of rotor aerodynamics.Design/methodology/approach – The calculations of the lift-drag characteristics of OAF and NACA63A312 airfoils at low speed are made using Jameson/TVD mixed scheme. By means of finite volume approach for numerical discretization and Runge-Kutta time-stepping advance, Euler/Navier-Stokes equations are solved. Furthermore, a model based on circular tiny segment momentum theory and blade element theory is established to study the thrust and power of ducted tail rotor.Findings – The results of the calculation demonstrate the feasibility of the established method for analyzing ducted tail rotor aerodynamic characteristics.Research limitations/implications – Although the global thrust and power of ducted tail-rotor could be obtained using current method, the exact flow filed (such as shroud pressure field and the flow over fan blade) calculations still rely on the complex three-dimensional CFD technique that should be studied in future.Practical implications – A very useful method for the preliminary design of the ducted tail rotor.Originality/value – By comparing the calculated results with those of relevant experiment, it is proved that the method developed here is suitable for the calculations in the field of rotor aerodynamics.
