Abstract
An aircraft wing assembly including a wing (3) and a wing tip device (4) at the tip of the wing (3), the wing tip device (4) having front and rear spars (14, 13), wherein the wing tip device (4) has a cross-brace spar (18) that links the front and rear spars and is oriented such that it is oblique to the front and rear spars (14, 13).
Claims11
A wing assembly comprising:
- a wing including a tip and extending in a wing spanwise direction defined by a leading edge of the wing, and
- a wing tip device extending outwardly and upwardly from the tip, wherein the wing tip device includes:
- a leading edge swept back from the wing spanwise direction by a first swept back angle;
- a front spar extending outwardly and upwardly, wherein the front spar is swept back from the spanwise direction by a second swept back angle at least as great as the first swept back angle;
- a rear spar extending outwardly and upwardly, wherein the rear spar is swept back from the spanwise direction by a third swept back angle less than the second swept back angle, and
- a cross-brace spar linking the front spar to the rear spar and oblique to the front spar and the rear spar,
- wherein the cross-brace spar extends upwardly from an inboard location proximate the rear spar to an outboard location proximate the front spar, and
- wherein the cross-brace spar twists as the cross-brace spar extends upwardly.
5 more elements
A wing assembly comprising:
- a wing, and
- a wing tip device at a tip of the wing curving upwardly from the tip of the wing as the wing tip device extends outboard of the wing,
- wherein the wing tip device includes a front spar, a rear spar, and a cross-brace spar linking the front spar to the rear spar,
- wherein the cross-brace spar is oblique to the front spar and the rear spar,
- wherein the cross-brace spar includes an inboard end proximate one of the rear spar and the front spar, the cross-brace spar has a longitudinal axis extending from the inboard end to an outboard end, and the outboard end is proximate another of the front spar and the rear spar,
- wherein the longitudinal axis of the cross-brace spar curves in an upward direction as the cross-brace spar extends from the inboard end to the outboard end, and
- wherein the cross-brace spar twists about the longitudinal axis as the cross-brace spar extends from the inboard end to the outboard end, or the longitudinal axis of the cross-brace spar curves in a fore-aft direction as the cross-brace spar extends from the inboard end to the outboard end.
4 more elements
A wing tip device comprising:
- a wing tip device configured to be mounted to a tip of a wing,
- wherein the wing tip device extends upwardly from the tip of the wing as the wing tip device extends outboard of the wing in a spanwise direction of the wing,
- wherein the wing tip device includes a front spar, a rear spar, and a cross-brace spar linking the front spar to the rear spar,
- wherein the cross-brace spar is oriented oblique to the front and rear spars, and
- wherein the cross-brace spar includes an inboard end proximate one of the rear spar and the front spar, the cross-brace spar has a longitudinal axis extending from the inboard end to an outboard end, and the outboard end is proximate another of the front spar and the rear spar,
- wherein the longitudinal axis of the cross-brace spar curves in an upward direction as the cross-brace spar extends from the inboard end to the outboard end, and
- wherein the cross-brace spar twists about the longitudinal axis as the cross-brace spar extends from the inboard end to the outboard end, or the longitudinal axis of the cross-brace spar curves in a fore-aft direction as the cross-brace spar extends from the inboard end to the outboard end.
4 more elements
A wing assembly comprising:
- a wing, and
- a wing tip device at a tip of the wing extending upwardly from the tip of the wing as the wing tip device extends outboard of the wing in a spanwise direction of the wing, wherein the wing tip device includes a front spar, a rear spar, and a cross-brace spar linking the front spar to the rear spar,
- wherein the cross-brace spar is oblique to the front and rear spars, and
- wherein the cross-brace spar extends upwardly from an inboard location proximate one of the rear spar and the front spar to an outboard location proximate another of the front spar and the rear spar,
- wherein the cross-brace spar includes an inboard end and the cross-brace spar extends along a longitudinal axis to an outboard end, and
- wherein the cross-brace spar twists about the longitudinal axis as the cross-brace spar extends from the inboard end to the outboard end.
3 more elements
A wing assembly comprising:
- a wing, and
- a wing tip device at a tip of the wing extending upwardly from the tip of the wing as the wing tip device extends outboard of the wing in a spanwise direction of the wing, wherein the wing tip device includes a front spar, a rear spar, and a cross-brace spar linking the front spar to the rear spar,
- wherein the cross-brace spar is oblique to the front and rear spars,
- wherein the cross-brace spar extends upwardly from an inboard location proximate one of the rear spar and the front spar to an outboard location proximate another of the front spar and the rear spar, and
- wherein the cross-brace spar has an inboard end and the cross-brace spar extends along a longitudinal axis to an outboard end, and wherein the longitudinal axis curves in a fore-aft direction as it extends from the inboard end to the outboard end.
