Dufour Aerospace

Dufour Aerospace is a Swiss original equipment manufacturer specialising in the design and development of tilt-wing vertical take-off and landing (VTOL) aircraft. The company occupies a specific niche in the advanced air mobility sector, focusing on aerodynamic efficiency by combining the hovering capability of helicopters with the cruise speeds and range of conventional fixed-wing aircraft. Its engineering approach is rooted in Swiss aviation standards, targeting the transition from piloted to autonomous flight operations. The organisation’s primary development programmes include the Aero2, an uncrewed aerial vehicle designed for medical logistics and topographical mapping, and the Aero3, a larger piloted aircraft intended for emergency medical services and regional passenger transport. The company has secured partnerships and pre-order interest from helicopter operators and logistics providers, notably Air Zermatt, to test the viability of these platforms in demanding alpine environments. Prospective buyers and industrial partners should verify the current certification status of the Aero2 and Aero3 prototypes with the European Union Aviation Safety Agency (EASA). It is also advisable to confirm the timeline for full-scale production, the specific energy density specifications of their hybrid-electric propulsion systems, and the progress of flight testing programmes relative to stated commercial entry dates.
