The Polaris aircraft concept by the second-placed team from the University of Stuttgart
The most striking feature of the Polaris aircraft design by the team from the University of Stuttgart is the integration of an innovative turbo-electric propulsion system that uses liquid hydrogen for fuel. The striking, contra-rotating propellers that are easily accommodated between the side tail planes at the rear of the Polaris hugely raise the propulsion efficiency without increasing the noise emissions. The forward swept wings also reduce aerodynamic drag.
