Abstract: Aerodynamics analysis and evaluation are important for aircraft design. A technique called wake integration method for aerodynamics evaluation from the flow field solution using Euler equations is discussed. This paper gives detailed explanations to the method and uses different wings under different flow regimes to discuss and analyze. Results of the computation demonstrate that this method is fit for the aircraft design.

Key words: aerodynamics evaluation, wake integration, surface integration, drag decomposition
