Architecture and system design of a distributed actuation for a commercial aircraft Wing High Lift Devices (slats)

Pollution is a major problem to which the field aviation contributes more everyday. Today’s ecological problems create a general tendency to develop solutions that reduce greenhouse gases. The combination of a lighter plane and the improvement of new performances could reduce airplane pollution. We are therefore caught in a challenge to reduce the mass and increase the performance of planes which are two aspects that can oppose. Research shows that developing a More Electric Aircraft could bring a reduction of mass. This is why this dissertation focuses on the design of a new architecture that makes the deployment of slats and flaps independent from each other. Slats and flaps are removable parts of the wing that allow to increase the lift during takeoff and landing. The final proposition enhances performances by improving independent deployment and a distributing the mass in the wings better. A CAD model of the new system will be described together with a mass, power off-take and Mean Time Between Failure analysis in order to compare it with the current system. This will lead us to new perspectives for the continuity of this project.
