Research on the Application of Vortex Lattice Method and Doublet Lattice Method in Aerodynamic Analysis of the Wing of Solar-Powered Unmanned Aerial Vehicle

In this paper the application of doublet lattice method and vortex lattice method is discussed. A wing of a solar-powered unmanned aerial vehicle (UAV) is chosen as the model. Both the methods are used to calculating the pressure distribution. The results show that the two methods can be used for unsteady aerodynamic analysis of such aircraft in time domain and frequency domain respectively.
