He speaks with Audi Board Member for Technical Development Michael Dick about lifecycles, regenerative fuels and of the box cars that can find their own parking spot – or even fly. Ideas for new mobility – Michael Dick (left) in conversation with Professor Mirko Hornung. 16 Encounter Technology 17 Encounter Technology Text Photos Today’s new aircraft models will still Hermann Reil Myrzik und Jarisch be flying in 2040. After that, however, there will have to be some very different air- craft concepts – most likely with a radical departure from the current designs. Mirko Hornung Herr Hornung, Herr Dick, you are both working on the future of mobility, on the road and in the air. And you both have to think beyond the fa- miliar construct. How will we fly tomorrow and how will we drive? Hornung: For civil aviation passengers rather little is likely to change over the next few decades. This is due to the product cycle being far longer than for, say, automobiles. Today’s new aircraft such as the Boeing 787 or the Airbus A 350 will still be flying in the year 2040. After that, however, there will have to be some very different aircraft concepts – most likely with a radical departure from the current designs. You have brought along a model that looks very unusual indeed. Hornung: The Claire Liner is an aircraft concept devel- oped by Bauhaus Luftfahrt for transfer between the mega-cities of the future. With its circumferential airfoils and decoupled drive, we were able to reduce significantly its kerosene consumption and noise emissions. Our drive concept separates the core drive unit and thus the power generation from the means of forward propul- Professor Dr.-Ing.

Dick: What is the purpose of the unusual wing shape? Hornung: These box-wing airfoils deliver greater effi- ciency, less drag and less weight. With a conventional wing, the turbulence at the tips generates the largest proportion of drag. A closed wing eliminates this turbulence. Dick: When can we expect to see a prototype? Hornung: For us, the Claire Liner is primarily an integra- tion platform for new technologies. A flying prototype would call for a great deal more development work and financial investment. Herr Dick, you, too, have brought an unusual idea with you – in one-to-one scale. With the Audi urban concept, we have pre- Dick: With the Audi urban concept, we have presented sented an idea of how we envisage the a proposal for how we might imagine tomorrow’s driving in these way we might drive in metropolitan areas in metropolitan areas – as a new, young mobility concept with electric drive, with a high standard of safety and with a clear promise of future – with electric drive, a high level driving fun. During the development process we showed the project of safety and a clear promise of driving fun. to our children, who gave a lot of good input. At the end of the day, Michael Dick the urban concept is a minimalist concept for young people, to suit their habits and their changed approach to many of life’s issues. The reaction at the Frankfurt Auto Show was amazingly good and, since then, we have discussed it with more potential custom- er groups like parents with children. We are still working on this concept, which could enter series production, although we have yet to reach a decision on that. 1 1 Idea for new flying – the Claire Liner concept air- plane promises considerably lower emissions.
