Flow Field Analysis and Model Machine Verification of Wing

In view of the development and demand of long-haul UAV wing development, a bionic large aspect ratio wing is designed by studying the seagull glide attitude configuration. In order to further explore the flow field mechanism of the bionic wing, this paper analyzes the transient flow field of the wing based on the Lattice Boltzmann Method, and studies the influence of the feature of the seagull's convex wing on the flow field distribution and vorticity on the wing surface. The results show that the imitation seagull configuration wing produces a favorable vortex at the front bulge of the wing, which has enhanced airfoil adhesion and increases the stall angle of attack. The flow field variation of a large aspect ratio bionic wing with aeroelastic response is analyzed. The feasibility of the bionic wing was verified by designing a bionic aircraft model for flight test.
