Agility Prime (X20.D) :
Revolutionary Coaxial Propulsors for Ultra-Quiet eVT
An aeroacoustically optimized counter-rotating, coaxial propulsor with novel aeroacoustic planform shaping that is 8 times quieter (~18 dBA noise reduction) than traditional eVTOL propellers, along with superior aerodynamic performance in hover and forward flight. An early version of this technology has been proven via high-fidelity simulations and flight testing with acoustic measurements in hover at two vastly different scales: 550 lb. personal air vehicle & 22 lb. UAS.
