    • A variable wing tip (18) for securing to a variable camber leading edge portion (12) of an aircraft wing (10). The wing tip has a normal fore and aft camber in an upper position and is adapted to have an increased camber curvature in a deflected down position. In the down position, the wing tip has a compound curvature, is shortened in the fore and aft direction ad is generally thickened in depth in a substantial portion of the wing tip. By operation of an actuator (96) in the leading edge (21), a multiple of generally parallel scissor plates (30,32) are pivoted apart. The plates extend in an inboard outboard direction and are spaced in the fore and aft direction. The scissor plates are pairs of upper and lower plates with respect to the upper and lower surface of the wing tip, the upper plates (30) being adapted to be pivotally secured inboard to a complementary outer portion of the wing leading edge to secure the upper portion of the wing tip thereto, and the lower plates (32) being pivotally and slidably secured inboard within the wing tip and being adapted to be secured to a complementary outer portion of the wing leading edge to secure the lower portion of the wing tip thereto. Each respective pair of upper and lower plates are pivotally secured together outboard (40) adjacent and outboard leading edge (42) of the wing tip. Respective upper and lower plates are adapted to be pivoted apart inwardly of and on the outboard pivots (40) when the camber is increased in the down position so as to increase the depth of and shorten the fore and aft direction of the wing tip. An elastomer (84) is bonded to the plates, permitting the plates to be pivoted apart. An elastomeric wing tip configuration (88), is secured to the wing leading edge and to a forwardly facing edge of the wing. The elastomeric configuration has the normal camber of the wing tip in the upper position and the increased camber and compound curvature of the wing tip in the deflected position. It forms continuous surfaces in the varied camber positions with the wing.

    • Apparatuses and methods for joining composite members and other structural members in aircraft wings and other structures. An aircraft wing box structure configured in accordance with one embodiment of the invention includes a first composite member having a first surface portion positioned at an angel relative to a second surface portion of a second composite member. The wing box structure of this embodiment further includes at least one metallic joining member having an upstanding leg portion extending from a base portion. The base portion of the joining member is bonded to the first surface portion of the first composite member with a first portion of adhesive, and the upstanding leg portion of the metallic joining member is bonded to the second surface portion of the second composite member with a second portion of adhesive.
