Dufour Aero3 Data

Full tilt‑wing capability allows true VTOL performance like a helicopter, yet efficient cruise speeds akin to a plane (≈ 350 km/h)
Equipped with six wing‑mounted propellers plus two tail propellers, all electric, offering redundancy and enhanced safety

Designed for 6–8 occupants with a roomy cabin and wide doors suitable for passengers, medevac stretchers, or cargo

Uses a hybrid system: electric VTOL take‑off/landing plus combustion-assisted cruise for long endurance—≈ three hours flight, ≈ 1 020 km range .

Initially aimed at air ambulance and EMS, it’s also suitable for air taxi, VIP transport, surveillance, and urban logistics
Undergoing development in tandem with Swiss Air‑Rescue REGA for medical evacuation customization.

Built to meet EASA SC‑VTOL standards and IFR operations
Employs prop-wash control and a “fully-washed vertical wing” for exceptional stability in gusty conditions, plus distributed thrust redundancy for safe operations

Quieter than traditional helicopters thanks to electric VTOL, quick transition to forward flight, and rapid climb minimizing ground noise exposure
Promises lower operating costs and environmental impact, claiming to do 80% of current helicopter missions at a fraction of the cost

Concept draws from the classic Canadair CL‑84 tilt‑wing but with modern electric-propulsion and software-synchronization, eliminating old mechanical complexity
