French company Ascendance Flight Technologies offers a four-seat design that combines hybrid propulsion with vertical takeoff and landing capabilities, and then scoots around on conventional wings. Etea’s technology seems a lot like that of Pipistrel’s 801 or several other eVTOLs. Some Historical Perspective The design team at Ascendance comes from Airbus, and claims to have made the first electric aircraft flight across the English Channel with the E-Fan 2.0. Your editor offers a few minor inclusions. First, as we reported on October 10, 2009, “Gerard Thevenot, a long-time championship-level hang-glider pilot, celebrated the centennial of Louis Bleriot’s flight across la Manche by flying his hydrogen-powered La Mouette hang glider over roughly the same route Bleriot took between Calais and Dover on …
Solar Sails for Ultralights?
Ultralights have done many spectacular things, including topping Mt. Everest and crossing the English Channel. Gerard Thevenot flew the Channel under a La Mouette wing powered by an Eck/Geiger motor driven by three fuel cells in 2009 – six years before the recent flights with faster electric craft. For that matter, Paul MacCready and his team flew a solar-powered aircraft from near Paris to an RAF runway on the eastern English coast in 1981. Hang gliders, paramotors, and other rigid and non-rigid-wing craft might benefit from new sailcloth that incorporates flexible solar cells into its makeup. Used on sailboats, the solar fabric helps run auxiliary motors and can help extend the cruising range of a boat when the sails are …
