Headline: Air Taxi Company Complete First Phase of VTOL Flight Testing
Caption: VIDEO AVAILABLE: info@covermg.com ... While many so-called ‘air taxi’ companies have just fancy renderings to show for their ideas, a Swiss company have announced, on 27 July, completion of the first phase of VTOL tech demonstrator flight testing. Dufour Aerospace have carried out 550 test flights of the two-wing craft, expanding the flight envelope incrementally. They say: “We have demonstrated a high degree of stability and control in all conditions, including transitions from hover to cruise and back again.” Developed in partnership with the ETH Zurich research institute, the fully-electric aircraft has a 4.5-metre (14.8-ft) wingspan. Dufour vision is to build the aEro VTOL, an advanced electric aircraft they say aims to bring “you from your doorstep to nearly anywhere you want over 5 times faster than a car but at the same cost per kilometer.” The company explain that they have been inspired by Canadair’s pioneering work fifty years ago with the CL-84, and their research has shown that tilt-wing convertible aircraft offer a high degree of safety and efficiency. They say: “Building on our experience in manned electric flight with our aerobatic plane aEro 1, we are proud to announce that we have completed the first phase of flight testing of our VTOL technology demonstrator aircraft.” Felix Rubin, lead engineer for aerodynamics, commented, “At larger scales, slipstream airflows over tilting wings become more turbulent and harder to predict, and care is needed to ensure that the aircraft remains stable during transition. With this large-scale unmanned aircraft, we’ve now been able to demonstrate that we can achieve that stability at high Reynolds numbers.” Jasmine Kent, CTO, commented, “From our simulations, we expected that our proprietary tilt-wing control system, developed over the last two years in collaboration with ETH Zurich, would perform well. But it’s encouraging to see that its performance and stability exceeded our expectations.” Thomas Pfammatter, CEO, commented, “I’m proud that the team has been able to build on the electric propulsion technology and flight test processes we pioneered with aEro 1. We now have solid experience with both manned electric fixed-wing and eVTOL technology. As a helicopter rescue pilot, I’m looking forward to bringing these together.”
