Possibly Euler or potential-move calculations predict the strain distribution over the airfoil surfaces around correctly for angles of attack underneath stall, where they may pass up the entire lift by up to ten–20%. The mix of the wingtip vortices plus the vortex sheets feeding them is called the vortex wake. https://franciscoludk29620.vidublog.com/32477023/maximizing-space-with-a-motorized-garage-storage-lift
