EPFL (Ecole Polytechnique Fédérale de Lausanne) is one of the two higher technical schools of Switzerland; its mission is research and development, industrial collaboration, innovation and teaching. Currently 7500 students and 4000 collaborators (research, development, teaching) study or work at EPFL, spread among  5 faculties - Fundamental Sciences (SB), Engineering (STI), Communication and Computer Science (IC), Environmental Sciences, Architecture, Civil and Environmental Engineering (ENAC) and Life sciences (SV). The team involved in CleanLE2 project is part of the Engineering faculty and belongs to the Interdisciplinary Aerodynamics Group.
EPFL is project leader, and as such responsible for the management of the CleanLE2 project. Additionally EPFL is in charge of parts of the design of the prototype and supports AEDS by performing finite element analysis of the prototype structure.


Advanced Engineering Design Solutions (AEDS) is an SME based in Valais, Switzerland, specialised in design solutions for the aerospace and energy sectors. The members are specialists of flight physics, design, systems engineering, acoustic predictions, aero-acoustics, system optimisation, computational fluid dynamics (CFD) and thermal physics.
AEDS is responsible for the CleanLE2 prototype design and optimisation. In addition, AEDS is in charge of the establishment of a computational fluid dynamics (CFD) database for estimating the aerodynamic loads on the cleaning device in flight.

The Zurich University of Applied Sciences, located in the city of Winterthur, is one of the largest University of Applied Sciences in Switzerland. ZHAW Centre for Aviation (ZAV), the Centre for Product and Process Development (ZPP) and the Institute of Materials and Process Engineering (IMPE) are involved in the project.
ZHAW mission in the CleanLE2 project is to carry out preliminary experimental tests to support the design work and later to design a test rig for evaluating the performances of the prototype. Moreover, ZHAW is responsible for the manufacturing of the test bench and of the prototype, as well as for the execution of the ground test campaign.

Pprime Institut Pprime is a CNRS laboratory created in 2010 and based in Poitiers, France. It depends from the University of Poitiers, ENSI Poitiers and Ensma. Pprime employs more than 500 people and is an excellence centre for natural sciences and engineering.
In the CleanLE2 project Pprime is responsible for wind tunnel testing of the prototype, as well as manufacturing, assembly and instrumentation of the wind tunnel model.
