    摘要: The present invention provides a nose cone structure for a pylon (20) of an aircraft with a wing-mounted layout. The nose cone comprises a front nose cone (21) located in front of a wing leading edge (31) and a rear nose cone (22) located behind the wing leading edge (31). The nose cone is characterized in that at least a part of the rear nose cone (22) is modeled and shaped by cross section control segments and comprises at least one group of latitudinal position control segments (P01, P02, P03, P04) and at least a group of longitudinal position control segments (S01, S02, S03, S04, S05). The rear nose cone of the pylon is shaped by latitudinal position control segments. The pylon design of the present application optimizes the passageway area of the space between the pylon/wing/engine nacelle by controlling the rear nose cone curvature of the pylon without deflection of the rear portion of the pylon.

    摘要: Provided is an airplane suspension (20) fairing structure with a wing-mounted arrangement, the fairing structure comprising a front fairing located in front of the leading edge (31) of a wing and a rear fairing located at the back of the leading edge (31) of the wing; the vertical section line (G) of the front fairing is curved, ascending along air flow direction from a start point (p) of an engine nacelle (10) to the maximum height position and then descending and extending below the lower surface (32) of the wing. In the present invention, due to the curved vertical section line of the front fairing of the suspension, inner space of the suspension is met only in the position requiring greater inner space, thus enabling the engine to be mounted close to the wing without additional devices; and the fairing aerodynamic surface of the suspension will not extend to the upper surface of the wing, avoiding interference of the suspension with the wing during cruising.

    摘要: An aircraft wingtip device, comprising a transition part (1) and a wingtip part (2); the inner end of the transition part (1) is connected to the far end of an aircraft wing, and the outer end of the transition part is connected to the wingtip part (2); the wingtip part comprises a plurality of wingtip sections (3 n ), and each wingtip section (3 n ) comprises a wingtip (4 n ) and a wing root (5 n ) respectively; the wing root (5 1 ) of the first wingtip section (3 1 ) is connected to the outer end of the transition part (1), the wing root (5 n+1 ) of the n+1 wingtip section (3 n+1 ) is located on the wingtip (4 n ) of the n wingtip section (3 n ), and the chord length of the wing root (5 n+1 ) of the n+1 wingtip section (3 n+1 ) is smaller than or equal to the chord length of the wingtip (4 n ) of the nth wingtip section (3 n ), where n > 0. Because the wingtip device of the present invention is disposed in a stepped fashion, more than one discontinuity surface is added to the wingtip thereof, so that the wingtip vortices induced by the wingtip suppress each other, thereby reducing the strength of the vortices, and thus achieving drag reduction effect. In addition, the wing root of the present invention has a smaller bending moment increment, thus reducing the structural weight of the airplane and having less effect on the flutter properties.
