Fluid Structure Interaction Simulation on the Bionic Airfoil of the Small Unmanned Plane

The quality and dependability of the small unmanned plane is more and more important currently. For the small unmanned plane under the conditions of Low-Reynolds, the air viscosity has relatively greater influence on its aerodynamic performance. This is one of the greatest difficulties to design a small unmanned plane. The aerodynamic performance of bionic aerofoil and NACA 4412 is contrastively analyzed while the Reynolds-Number is and by the Fluent. The computational result and the analysis show that the fluid-structure interaction is an important issue to consider while designing the small unmanned plane.
