Aerodynamic analysis of different airfoils in diagonal shear variable-sweep wings

The diagonal shear variable-sweep wing changes the relative thickness of the airfoil while changing the sweep angle, which effectively improves the aerodynamic performance of the aircraft for complex flight conditions. In order to explore the problem of maintaining the optimal flight performance of the diagonal shear variable-sweep wing under different flight conditions, five NACA airfoil assemblies with different relative thicknesses are established, and the numerical simulation of the perturbed flow field in a wide speed domain is carried out to analyze the aerodynamic performance under different angles of attack (AoA) and speeds.
