The main objective of this project was to explore the possible solutions for cleaning devices capable of clearing out the leading edges of business jets or airliners. Particular attention was carried out in the modification of already existing devices on sailplanes. The cleaning concept was compatible with the surface treatment/coating of the leading edge of commercial aircrafts.

In the first step, the work focused on concept trade-offs. Innovative solutions were compared with the already existing devices used for sailplanes. An evolution of the existing systems was their adaptation for wings with high lift devices, such as slats, and also for the space left inside the wing because of the presence of fuel tanks. Then, the dynamic elements of the already existing systems, which are actuated by hand or compact electrical motors, were redesigned because of the difference in efforts acting on an aircraft and a sailplane; but also, to ensure the level required by civil aviation certification.

The consortium was led by EPFL with a small company in Austria for consultancy on the sailplane devices.
