Keywords: airfoils, lift curves, low Reynolds number

The aim of this paper is to determine the reasons for the abnormal behavior of the lift curves for various airfoils by investigating their pressure distribution and flow line plots using a computational fluid dynamics (CFD) program and also find common physical parameters between airfoils that may lead to the display of similar undesired flight characteristics in their lift curves.
