Whisper Aero tests its ultra-quiet electric propulsors in crewed flight
Whisper Aero has successfully completed the first crewed flight demonstration of its ultra-quiet electric ducted fans.
TL;DR
The company used an Aeriane Swift 3 glider equipped with its eQ250 propulsors, confirming that the engine noise was lower than the airframe's own aerodynamic noise. This technology could significantly reduce the noise footprint of future electric aircraft, a key requirement for the viability of urban air mobility.
