Abstract
An aircraft slat deployment mechanism including a first drive member coupled to a slat at a first pivot point and a second drive member coupled to the slat at a second pivot point offset from the first pivot point. A first rack is provided on the first drive member, and a first pinion is carried by the drive shaft. The first pinion is arranged to transmit mechanical power from the drive shaft to the first drive member via the first rack. A second rack is provided on the second drive member, and a second pinion is carried by the drive shaft. The second pinion has a different radius to the first pinion. The second pinion is arranged to transmit mechanical power from the drive shaft to the second drive member via the second rack, such that the first and second drive members move at a different speed.
