WebAug 24, 2014 · The geometry of the airfoils (NACA 2411 and 0012) is described with the help of parametric section method, and the flow around the airfoils is solved by using the Panel method. The constructed surrogate model is more accurate and limits their estimation error within the order of 10 −2 –10 −6. WebNACA equations can also be used as an airfoil generator [25]. Those equations lead to generate an airfoil from 4 to 5 parameters (i.e. NACA 4 or 5 digits) that is a good point for …

WebAug 1, 2024 · As mentioned before, important issue about the morphing wing design is the need for more actuators along the airfoil and therefore more weight penalty [22]. As a result, the amount of displacement is significant for most of the surface points to move the surface to the optimum shape geometry.

WebThe parametric study presents results from both viscous and inviscid computations. It should be noted that in this paper, except in Fig. 1, the airfoils will be shown "upside down," that is, flipped with respect to their orientation on the race car. Also, the airfoils will be referred to as having "high lift" rather than "high down force." WebAug 16, 2024 · At the moment there is a large catalog of aerodynamic airfoils for aircraft wings. The use of such airfoils in motorsport is possible, but is not the optimal solution because of several reasons. The aircraft wing must meet certain requirements in terms of generated pitching moment, have low values of drag to provide a high fuel efficiency and ...
