Next generation energy storage system
In addition to the considerable promise of this propulsion technology, VoltAir also opens up new possibilities in terms of aircraft design, which could benefit both the passenger and the environment. Unlike fuels that are burned in a combustion engine, the electric energy storage system does not change its mass during flight. This makes it possible to locate the batteries away from the aircraft’s centre of gravity, balancing the electric motors’ weight at the rear of the fuselage. The absence of wing-mounted engines and landing gear pods results in an aerodynamically very clean wing, reducing the energy needed to fly.
“This solution integrates a fully electric propulsion system which does not emit any carbon dioxide or nitrous oxide during flight. On top of that, the engines have an extremely low noise level, which makes it quieter for those living close to airports and, of course, for those travelling,” underlines Jan.
Did you know…?
Conventional electric motors are known to be very efficient but generally do not offer the power densities (energy output per unit weight/kilowatt per kilogram) required for large-scale airborne applications. The discovery of high-temperature superconducting (HTS) materials provides the key solution to this problem.
