Abstract:
1. A slat deployment mechanism for deploying a plurality of slats from a leading edge of an aircraft wing, the slat deployment mechanism comprising: at least two drive pinions drivingly coupled to each of said plurality of slats; at least one slat deployment motor; a common input drive shaft coupled to said at least two drive pinions so that operation of the slat deployment motor drives the common input drive shaft to rotate the at least two drive pinions drivingly to deploy the slats; at least two rotary actuators per slat, each of said at least two rotary actuators connecting said common input drive shaft to an output shaft connected to a corresponding one of said at least two drive pinions; at least one sensor associated with each of said at least two rotary actuators to generate signals indicative of the rate of rotation of each of said at least two output shafts; and a controller, configured to receive and analyse said signals from each of said at least two sensors and to generate an alarm signal in the event that the rate of rotation of said at least two output shafts differ.
