Experimental research on the flow flied of the nacelle and inlet of a civil aircraft with wind-mounted engines at low speed

Journal of Physics: Conference Series
Modern civil transport aircraft with wing-mounted engines are exposed to the upwash induced by the wing, resulting in the local angle of attack at the nacelle leading edge, notably greater than that of aircraft.
