    Abstract
  • Numerical simulation of an unmanned aerial vehicle (UAV) was carried out by 3D modeling and computational fluid dynamics (CFD) software, and then the coefficients of lift, drag and moment with a small angle of attack (AoA) variety as well as the distribution of pressure,density and velocity on the surface of UAV were obtained. Empirical estimation was also conducted and the results of the two methods were compared with each other. It shows that CFD has a satisfactory accuracy in the small-scale, low velocity flow simulation, and it plays an important role in the development of the UAV. The simulation results can provide a theoretical reference to the further optimization development of the UAV.
