AIRPLANE SUSPENSION COWLING STRUCTURE WITH WING-MOUNTED ARRANGEMENT

摘要

Provided is an airplane suspension (20) cowling structure with a wing-mounted arrangement, the cowling structure comprising a front cowling located in front of the leading edge (31) of a wing and a rear cowling located at the back of the leading edge (31) of the wing; the vertical section line (G) of the front cowling 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 cowling 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 cowling 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.
