The aerodynamic performance of a certain aircraft wing structure at different angles of attack was analyzed using FLUENT finite element software. According to simulation, the lower surface of the wing is a high-pressure zone, while the upper surface is a low-pressure zone. As the angle of attack increases, the high-pressure zone will move towards the leading edge of the wing, while the trailing edge of the wing slowly forms a low-pressure zone; At the same time, the airflow accelerates on the surface of the wing, causing a decrease in pressure and an increase in lift. This provides a theoretical basis for further optimizing the wing structure.
