Summary/Abstract: The aerodynamics of lifting surfaces has undergone a significant evolution determined both by conceptual perspective and by the materials used and related technologies. Accelerating this evolution was also possible due to the use of numerical modeling tools that offered and still offer computational speeds that were not possible a century ago. The constructive concepts of unmanned aerial vehicles(UAVs) offer complex aerodynamic approaches in terms of flight regimes, providing research opportunities on design and manufacturing limitations with direct effects on flight safety. The article wants to highlight critical flight from the perspective of using a freeware tool. The 2D aerodynamic analysis cases of the aerodynamic and 3D profiles of the simple lifting surface offer a perspective on the calculation possibilities both through the multiple case studies offered and the expressed results.
