CLEANLE2 · Demonstration of a Decontamination Device Protoype for buisness jets and Experimental Validation

This project is to validate a cleaning device capable of clearing out small debris from the leading edges of business jets or airliners, to keep the flow as laminar as possible on the leading edge of the wing. The cleaning concept will be compatible with the surface treatment of the leading edge of commercial aircrafts. Typically this concerns the contamination of leading edges by insect impact. At first, the system will be designed and a prototype manufactured. In parallel, aerodynamic and stress models will be studied. Then ground experiments including tests in a wind tunnel will be performed, in view of prototype validation.The prototype will be subsequently modified and validated. Conclusions will help for the industrialisation of the cleaning system.The consortium will be led by EPFL, who co-ordinated a preliminary project on the design of such cleaning devices in the CleanSky call 3 CLEANLE, with several partners for manufacturing, consulting, experiment running and analysis, including a design office SME, and university windtunnel experts. The project will lead to a test prototype.The present project will push the concepts, that have attained a Research Technology Readiness Level, TRL near to TRL3 (research to prove feasibility), to evolve on the system/subsystem model and prototype demonstrator of a technology demonstration of TRL 6.""
