The invention provides a corporate aircraft engine upper placement and front swept wing duck type layout, which belongs to the aviation field, and relates to a high lift drag ratio airplane total layout scheme. The airplane comprises a fuselage, duck wings, wings, a vertical fin, an engine and a rear body edge strip; the wing leading edge inner segment sweeps back; the wing leading edge outer segment sweeps forward, and the engine is supported on an upper surface of a rear body edge strip between a wing trailing edge and an edge strip rudder by an engine, and in the top view projection, an engine axis crosses the corner of the wing leading edge inner segment and the wing leading edge outer segment, and an elevator is arranged at the wing trailing edge, and an inner side elevating auxiliary wing is arranged at the inner side of the wing trailing edge inner side, and an outside elevating auxiliary wing is arranged at the outer side of the wing trailing edge; an edge strip rudder is arranged at the rear edge of the rear body edge strip, and a rudder is arranged at the rear edge of the vertical fin. The wing trailing edge inner segment is connected with a rear body edge strip; the edge strip rudder at the rear body edge strip trailing edge is in cracking type, and is composed of an upper rudder surface and a lower rudder surface, and the shapes of the fuselage and the wing are in smooth transition. The invention has the advantages of high rising and landing lift coefficient and high trim lift drag ratio, light structure weight, long endurance and long voyage.
