Webb3 okt. 2011 · The British, under the leadership of the great Cambridge mathematical physicist Lord Rayleigh, produced highly elaborate investigations of the nature of discontinuous flow, while the Germans, following Ludwig Prandtl in Göttingen, relied on the tradition called “technical mechanics” to explain the flow of air around a wing. WebbThe lifting line theory is a mathematical theory that predicts the distribution of lift over a wing. This theory is also called the Lanchester-Prandtl lifting line theory in honor of the people who independently came up with the model.
