Abstract
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.
