ACTUATION ASSEMBLY FOR MOVING A WING TIP DEVICE ON AN AIRCRAFT WING

摘要

An aircraft wing comprises a fixed wing and a wing tip device at the tip thereof. The wing tip device is configurable between: a flight configuration for use during flight and a ground configuration for use during ground-based operations to reduce the span. The wing comprises an actuation assembly for moving the wing tip device. The actuation assembly is arranged to move the wing tip device in a two-stage movement comprising a first stage in which the wing tip device is translated away from the flight configuration in a linear movement only, and a second, subsequent stage, in which the wing tip device is rotated to the ground configuration.

主权项

1. An aircraft wing comprising a fixed wing and a wing tip device at the tip thereof, wherein the wing tip device is configurable between:
(i) a flight configuration for use during flight and (ii) a ground configuration for use during ground-based operations, in which ground configuration the wing tip device is moved away from the flight configuration such that the span of the aircraft wing is reduced, wherein the wing comprises an actuation assembly for moving the wing tip device between the flight and the ground configuration, and wherein the actuation assembly is arranged to move the wing tip device from the flight configuration to the ground configuration in a two-stage movement, the two-stage movement comprising a first stage in which the wing tip device is translated away from the flight configuration in a linear movement only, and a second, subsequent stage, in which the wing tip device is rotated to the ground configuration.
