Quiet aviation propulsion system developer Whisper Aero on Tuesday unveiled a system designed to enable runway independence for conventional, short, or vertical takeoff and landing (VTOL) aircraft, from electric air taxis to military transporters.
Whisper last year unveiled its JetFoil propulsion system—which integrates the company’s “ultraquiet” electric engines and ducted fan system on a wing’s airfoil—for autonomous military platforms. At SAE International’s AeroTech 2026 event in Florida this week, the firm said the JetFoil could enable takeoffs with just 50 feet of ground roll using less than half the thrust of VTOL designs that use tilting propulsors. That covers many eVTOL (electric VTOL) air taxi concepts.
