摘要:
A structure comprising a space frame including a plurality of strut sections (11) which cross at one or more locations within the space frame to define a node (12) at each respective crossing location, wherein the strut sections (11) are laminates comprising a plurality of ply layers, and wherein the ply layers of the crossing strut sections (11) are interleaved at the node(s) (12). Also a method of forming the structure. Also An aerofoil structure, comprising a space frame defining a cage (9) adapted to receive upper and lower covers (5, 6) so as to form upper and lower aerodynamic surfaces of the aerofoil, and at least one spar extending generally spanwise across the structure, wherein the spar includes a spar web (7, 8) and upper and lower spar caps (10), and wherein the spar web (7, 8) is disposed on one of an interior or exterior side of the cage (9), and the spar caps (10) are attached to the other of the interior or exterior side of the cage (9).

An aerofoil structure (1) comprising at least two spars (2, 4) spaced apart in a fore and aft direction so as to define a fuel carrying volume between the spars, and at least one longitudinal corrugated reinforcing member (6, 7) disposed between the spars, each reinforcing member being corrugated in the longitudinal direction to form a series of forward ridges (9) on a forward side of the reinforcing member and a series of aft ridges (8) on an aft side of the reinforcing member, wherein each reinforcing member is directly attached by its forward ridges to one of the spars or to the aft ridges of an adjacent one of the reinforcing members, and wherein each reinforcing member is directly attached by its aft ridges to one of the spars or to the forward ridges of an adjacent one of the reinforcing members. Also, a method of manufacturing an aerofoil structure. The reinforcing member(s) may extend substantially the entire length of the structure to reduce the number of manufactured parts of the structure, increase the stiffness of the structure and reduce the weight of the structure.

The disclosure relates to aircraft wings, aircraft, and related methods. Aircraft wings include a spoiler constructed substantially of a monolithic structural body with an upper side that defines a portion of an airfoil surface of an aircraft wing. The monolithic structural body further includes a lower side, opposite the upper side, that includes a plurality of stiffening ribs that define a plurality of open voids. Methods of constructing a spoiler for an aircraft wing include forming a monolithic structural body of the spoiler.

L'invention concerne un caisson central de voilure d'aéronef comportant un panneau supérieur (1031), un panneau inférieur (1032), un longeron avant (1033), un longeron arrière (1034), et au moins une nervure courante. Selon l'invention, une nervure courante comprend deux pièces de raidissement (410A, 410B), une première pièce de raidissement (410A) s'étendant adjacente au panneau supérieur (1031) et à l'un parmi le longeron avant (1033) et le longeron arrière, et une seconde pièce de raidissement (410B) s'étendant adjacente au panneau inférieur (1032) et à l'autre parmi le longeron avant et le longeron arrière (1034). L'invention met en oeuvre un nombre réduit de pièces, ce qui simplifie le montage du caisson central de voilure d'aéronef, en particulier l'installation des nervures courantes.
摘要:
An aircraft wing has a plurality of wing segments (52) mounted on a wing spar (60 by joints (56) that allow relative movement between the spar and the wing segments. Tuning of coefficients of thermal expansion is employed to reduce induced stresses from changes in temperature.
