Problems solved by technology

Lightweight materials can be used to make strong and lightweight truss structures, but to provide adequate load transfer between truss structural elements, current composite ribs are complex to manufacture and generally heavy
Wings that use composite ribs in the wing are also difficult to assemble

Embodiment Construction

[0012] [0012] The following detailed description illustrates the disclosure by way of illustration and not limitation. Obviously, this description will enable one skilled in the art to make and use the disclosure, describes several embodiments, adaptations, changes, substitutions and uses of the disclosure, including what is presently considered the best mode of the disclosure.

[0013] 【0013】 figure 1 is an isometric cross-sectional view of an airfoil structure 100 according to an embodiment of the disclosure. In the exemplary embodiment, wing structure 100 includes a plurality of truss rib assemblies 102 extending forward 104 and aft 106 between leading edge 108 and trailing edge 110 of wing structure 100 . The wing structure 100 also includes a front spar 112 and a rear spar 114 extending from the fuselage (not shown) of the aircraft. Lower wing skin 116 is attached to the lower portion of truss rib assembly 102 between leading edge 108 and trailing edge 110 . Similarly,...

Abstract

Methods and structures for a composite truss structure are provided. The structure includes an upper chord member, a lower chord member, and a plurality of web members extending therebetween. Each of the upper chord member, the lower chord member, and the plurality of web members are formed of a continuous composite fiber positioned in each of the upper chord member, the lower chord member, and each of the plurality of web members wherein each of the upper chord member, the lower chord member, and the plurality of web members includes a predetermined number of passes of the continuous composite fiber corresponding to a predetermined load. The composite truss structure also includes at least a first gusseting plate coupled to the upper chord member, the lower chord member, and the plurality of web members.

Description

technical field [0001] [0001] Embodiments of the present disclosure relate generally to methods and structures for forming lightweight truss members, and more particularly, to methods and structures for forming composite rib and fuselage truss members. Background technique [0002] [0002] Conventional airfoil constructions generally include one or more spars extending laterally with respect to the longitudinal axis of the fuselage to support a plurality of longitudinally extending and laterally spaced ribs that define the shape of the airfoil. The vertical web portion of the rib includes structural elements configured to carry compressive and tensile loads to maintain the shape of the airfoil. The truss design of the wing ribs is an effective method of transferring and distributing loads throughout the wing structure. In addition, truss structures are also used in bridges, floors, and other support structures. At least some known truss structures are relatively heavy due t...
