EcoPulse, the hybrid-electric technology demonstrator aircraft being jointly developed by Daher, Safran, and Airbus, has started its flight-test campaign. On Tuesday, the partners announced that the first flight happened on November 29, with the converted Daher TBM 910 taking off from Tarbes Airport in the southwest of France for a 100-minute sortie.

During the flight, pilots deployed all parts of the powertrain, including the six 50-kilowatt electric power units, the turbogenerator, and six sets of electric thrusters, or “e-propellers,” installed along the wing. The flight tests will validate the results of earlier ground testing and also 10 hours of flight tests that were conducted without the electric propulsion system functioning in May and June. The first test evaluated the flight control computer and high-voltage battery pack.
