Numerical simulation and wind tunnel experiment on aerodynamic characteristics of an electric aircraft

Taking an electric aircraft with high aspect ratio as the object of research, the CFD numerical simulation based on Navier-Stokes calculation and Spalart-Allmaras onflow pattern is conducted to verify the aerodynamic design and evaluate the flight property and quality of aircraft. With the aim of verifying the reasonability of the CFD calculation, a wind tunnel experiment was conducted for evaluation. The results indicate that the simulation information coincide well with wind tunnel test data, indicating that the simulation method could provide a guidance for the aerodynamic design of electric aircrafts, especially those with high aspect ratio.
