"Webeffect on lift. In England, Prandtl's lifting line theory is referred to as the Lanchester-Prandtl theory. This is because the English scientist Frederick Lanchester published the foundation for Prandtl's theory years earlier. In his 1907 book Aerodynamics, Lanchester had described his model for the vortices that occur behind wings during flight. " - Prandtl's lifting line theory
