To export the mass file, under “Plane”->”Current Plane” again, go to “Define Inertia”. It is also known as the Lanchester–Prandtl wing theory. The Prandtl lifting-line theory is a mathematical model that predicts lift distribution over a three-dimensional wing based on its geometry. what reference of airfoil is used to define lift and drag Ask Question Asked 2 years, 4 months ago. The relationship between wing area and body weight is given in kilograms per square metre (or grams per square centimetre). Wing loading is a measurement that relates the mass of an aircraft or bird to the total wing area. Wing design and analysis capabilities based on the Lifiting Line Theory, on the Vortex Lattice Method, and on a 3D Panel Method. It includes: XFoil’s Direct and Inverse analysis capabilities. XFLR5 is an analysis tool for airfoils, wings and planes operating at low Reynolds Numbers. XFOIL predictions are comparable to those of other turbulence and transition methods. The ease of use of XFOIL compared to the more complex CFD performed in ANSYS Fluent® and OpenFoam encourages its use at low speeds and for single-element airfoils. The user of modern computer operating systems is averse to the unfriendly interfaces of the bygone MS-DOS era. Xfoil is widely used in the aircraft industry and generally speaking is a reliable tool, although, in the view of this author, it suffers from a poor user interface when compared to many other codes.

NACA airfoils map a four digit code to an airfoil shape. The shape of the NACA airfoils is described using a series of digits following the word “NACA”. The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA).
