Study on lift enhancement for upper surface blowing system with electric ducted fan

The upper surface blowing (USB) technology is considered to be an effective active control technology, which can improve the aerodynamic performances of vehicle. In this paper, numerical simulation is used to investigate the aerodynamic interaction of electric ducted fan on airfoil. It is observed that the electric ducted fan jet on the upper wing leads to pronounced improvements on the aerodynamic performance in terms of the lift. In addition, the study found that electric ducted fans with different layout have an impact on the aerodynamic of airfoil.
