초록

An aircraft comprises a wing tip device, for example a winglet, a raked-tip device, a wing tip fence or a planar wing extension, mounted in the region of the tip of a wing on the aircraft. The wing tip device is rotatably moveable between a first position and a second position, in which the upward lift produced by the wing or the wing tip device is reduced. During flight, the bending moment at the root of the aircraft wing therefore changes in dependence on the position of the wing tip device. The maximum bending moment in the aircraft wing sustained dur...

청구항

The invention claimed is: 1. An aircraft comprising a wing, the wing comprising a root, a tip, and a wingtip device mounted in the region of the tip, there being a first plane with which the wing is generally aligned, and a second plane which is vertical and includes the longitudinal axis of the aircraft, the wingtip device being rotatably moveable between a first position and a second position, and being so arranged that, during flight of the aircraft, the bending moment at the root changes in dependence on the position of the wingtip device so that th...
