A simplified model to calculate the lift of 2D multi-foil and the distribution optimization of multi-foil |

| Abstract: | The dynamics of flow around multi-foil was addressed within the potential flow theory. Combined with the linear thin fin theory, the lumped vortex method was utilized to construct a simplified model, which could be used to calculate the lift force of the multi-foil simple and effectively. Based on the devised model, the impact on the lift force by the different number and distance of foils was analyzed, and obtained the optimal distance of foils to maximize the total lift force. |
