Retax project in a nutshellThe goal of RETAX is to explore intrinsically safe and efficient solutions for mid-size rotorcraft autonomous taxiing on ground and to select the most promising solution and develop it into a technical demonstrator to be tested and verified.The former experience of Michelin in electric-drive solutions will be used and translated into a rotorcraft electric taxiing system integrated with the landing gearA real demonstrator of the electric-drive system will be designed, engineered and built.

→ it’s a significant step towards greener rotorcraft operations

Retax website• English website• Hosting:

Two url : www.retax-project.org andwww.retax-project.comStand-alone solution

• Followed principles:Flexible tool, easy to update - web interface with a CMS (Content Management System / Open Source) allowing content updatesThe goal is to be fully referenced and listed in search engines

RecommendationsGood :

Availability and reactivity of Clean Sky staff

Average : Visibility of Clean Skysynergies with other JTIs?reach out to other sectors (energy, military, car)

Food for thought : Actual communication vs the submitted strategy depends on:

• ad-hoc evaluation and milestones of the project• on the industrial partner• project very close to market launch or not• IPR situation
