Abstract
This document shows the results of a part of the direct design process of airfoils. The research and design of these geometric shapes are of great relevance for their application in aerodynamic devices, since, if a wing profile with a great aerodynamic fineness is developed, the efficiency of the devices that have this geometric shape will be improved on its wings, propellers, etc. This project started from two analytical processes, the first was to obtain the shape of the wing profiles through the Joukowsky transformation, later the pressure distribution of each aerodynamic profile was obtained through the methodology developed by Theodorsen, the profiles that achieved optimal results were subjected to the third and last analysis in the Qblade software, this software allows to find the angle of attack that produces the maximum aerodynamic fineness, in addition to an approximation to the lift and drag coefficients, in this way several curved and aerodynamic profiles were obtained. Various thicknesses whose aerodynamic fines range between 100 and 250 at the optimum angle of attack.
