Abstract
Based on the distributed hybrid electric propulsion aircraft technology，we conducted numerical simulation and analysis on propulsive/aerodynamic coupled characteristics of the Distributed-Propulsion-Wing（DPW）during for⁃ ward flight. Firstly，the parametric model of the DPW was constructed in the component dismantling way by using the super-elliptic equation，the fourth-order Bezier curve，and the Class Function/Shape Function Transformation（CST）arameterization method. Secondly，the numerical analysis on propulsive/aerodynamic coupled characteristics of the DPW sectional airfoil，the unit DPW section，and the whole DPW was carried out in sequence，and comparison with the conventional airfoil-wing performance parameterization. Finally，the internal relationships between the internal and external flow coupling effect and the section-wing performance similar to airfoil-wing were discussed，and suggestions on the propulsion/ aerodynamic integrated design of DPW were presented.
