Abstract
An aircraft wing assembly comprising: a wing; a spoiler pivotally attached to the wing; and a spoiler deployment mechanism. The deployment mechanism comprises a scissor linkage mechanism comprising an upper link pivotally attached to the spoiler at an upper pivot, and a lower link pivotally attached to the wing at a lower pivot and to the upper link at a central pivot. An actuator is pivotally attached to the wing at a proximal pivot and to the scissor linkage mechanism at a distal pivot. The actuator is adjustable between expanded and contracted configurations so as to vary the distance between the proximal and distal pivots. This opens up the angle between the upper and lower links of the scissor linkage mechanism and pushes the spoiler up into the air-stream above the wing.
