Title: Determination of the aerodynamic characteristics of a light aircraft using ANSYS workbench and FLUENT software
Keywords: Light aircraft, Computational Fluid dynamics, ANSYS Workbench, Fluent
Abstract: The goal of this paper is to describe the process of modeling and simulation of computational fluid dynamics (CFD) problems that occur in aerodynamic aircraft design. The main focus is the simulation of the airflow around the light aircraft. The fluid flow simulations are obtained by FLUENT software. The Spalart-Allmaras method is chosen for a turbulent model. Another important step is the generation of an appropriate mesh around aircraft. The mesh is generated by ANSYS Workbench software. The lift and drag polars, side force coefficient, pitching, yawing and rolling moment coefficients are obtained at different angles of attack and sideslip, for a light aircraft with mass 840 kg, and span 11.6 m. An evaluation of the impact of the parts of the airplane on the aerodynamic characteristics is made. The obtained results give a possibility to improve the aerodynamic design of the given light aircraft.
