Duxion Motors is testing its patented eJet motor for electric aviation at low and high speeds. The eJet motor utilises permanent magnet technology and a new hybrid cooling system to achieve a better power-to-weight ratio for the electrification of jet aircraft. The integrated ducted fan system supplements the liquid cooling system with active convection cooling to increase power density.
The new technology of the jet engine
Previous systems suffered from strong vibrations, which led to frequent maintenance. With the eJet motor, this is prevented by integrating the fan blades into the motor. This eliminates the need to drive the fan blades, which increases drive efficiency and overall efficiency. Increase the overall efficiency. The technical challenges of this solution lie in the centrifugal forces acting on the fan blades at higher motor speeds. Some components of the rotor must be radially preloaded during production in order to reduce the load during operation.
Electromobility in the air
‘The eJet engine is the world’s first rim-driven jet propulsion system that achieves the thrust of a jet engine, but without the associated emissions,’ explains Rick Pilgrim, Chairman and CEO of Duxion Motors. Even though there is still a lot of research work to be done, the first steps towards electric mobility in the air have been taken.
