Small fans, all things considered, deliver thrust less efficiently than big ones. Lilium might have the best-looking aircraft in the eVTOL game, but it uses 36 tiny fans where competitors use six to ...

One thing nearly all air taxi concepts share in common is fast-spinning propellers or ducted fans somewhere outside the aircraft's fuselage, pushing air to develop thrust whichever way they're pointed ...

Most of the work so far on the electrification of aviation has involved propeller-driven aircraft and the development of electric propulsion units that can replace turboprop engines. Now GKN Aerospace ...

Whisper Aero doesn't plan to actually make the Whisper Jet, but this vision shows how 11 small ducted fans could be mounted on each wing. The jet engines on commercial airplanes can be absolutely huge ...

Ducted fans have emerged as a promising propulsion solution for modern Unmanned Aerial Vehicles (UAVs), particularly in applications that demand high safety, efficiency and low noise levels. Enclosing ...
