Dufour Aerospace and Swiss Air-Rescue (Rega) are to cooperate on the development of the air ambulance version of Dufour’s new Aero3 VTOL aircraft.

The Aero3 is a piloted tilt-wing aircraft featuring a hybrid-electric propulsion system. It is an extension of the Aero2, a smaller, unmanned version of the design which was test-flown by Dufour for the first time in 2020.

According to Dufour, the Aero3’s cabin space, load and range will make it well suited for emergency medical services and patient transport missions. During the development of air ambulance variant, Rega will support Dufour with know-how on medical and aviation equipment, and will advise on operational standards and certification.

Rega’s CEO, Ernst Kohler, said: “Continuous development is in Rega’s DNA. The Aero3 is an exceptionally interesting aircraft, and we want to support its development with our experience from 70 years of HEMS operation.”

Thomas Pfammatter, CEO of Dufour Aerospace, explained: “The collaboration with Rega will challenge Dufour Aerospace and advance our product development. They are a global leader in air rescue with the highest standards. Through this partnership, we will better understand and meet the needs of our customers.

“The Aero3 will meet the requirements for demanding patient transport, combining vertical take-off with sufficient load, high speed and range. Aero3 will be more efficient, less expensive and quieter than today’s helicopters, and will integrate seamlessly with existing infrastructure and systems.”
