Comparative analysis and manufacturing of airfoil structures suitable for use at low speeds

Abstract

An aerodynamic technique for calculating lift and drag coefficients is one of the required instruments in the wing design process. In recent decades, several tools and software have been developed based on aerodynamics and numerical methods. Today, aircraft architecture needs a great deal of calculation. To prevent expensive model testing, modern technologists use numerous simulation techniques. The present work explains how wing profiles can be modelled using ANSYS Fluent and tested by low velocity testing in the light of experimental literature results. With the chosen wing profile, the geometries formed in two dimensions and designed in 3 dimensions. As the method of study of the wing profiles, computational fluid dynamics (CFD) was chosen. In the approximation area equal to the true wind tunnel scale, Wing profiles formed at 0 to 20-degree attack angles are solved and equations are solved with the RNG k-Epsilon turbulence model. With Ansys Mesher, the grid development process was carried out, the solution stage and the result show operations were carried out with the CFD Post software. The study of the low velocity and high transport wing profiles, the drag coefficient, the lift coefficient, and the effect on the lift-drag ratio were studied using a numerical procedure. After the high efficiency of wing profiles was obtained, the production of a selected profile was started by making a static examination.
