The largest civil aviation aircraft in operation, Boeing 787 and A380, have very strong wingtip eddies. Wingtip eddy currents generally have many adverse effects on the aircraft in its range of influence. The influence of tip eddy current will cause different wash angles in different areas after the aircraft. The purpose of this method is to obtain the wash angle at different positions by using the calculated data. The wash angle obtained has important reference significance for the wash correction and risk assessment of aircraft flying in the tip swirl region.
