EcoPulse Debut at Paris Highlights Progress on Sustainable Solutions

The distributed power demonstrated by CORAC-led collaboration between Daher, Safran, and Airbus emerges as a theme in the drive toward a market-ready airplane.

Key Takeaways:

  • The EcoPulse project is a collaborative effort by Daher, Safran, and Airbus, supported by French government agencies, focused on developing and testing hybrid-electric distributed propulsion technology for aviation decarbonization.
  • Utilizing a modified Daher TBM 900 airframe, the demonstrator integrates six wing-mounted electric motors, a turbogenerator, and a battery pack, managing an 800-volt electrical system to gather critical data for future commercial hybrid aircraft.
  • After extensive ground and initial flight testing with conventional power, EcoPulse is preparing for its first flight engaging the electric motors in summer 2023, with a strategic goal to launch a market-ready hybrid aircraft by the end of 2027.

The concept of distributed power—thrust produced not from a single point on an airframe—began with the Wrights and their extremely light twin. When exploring the feasibility of utilizing electric motors—which tend to be lower output, lighter, and cooler in operation than their fossil-burning brethren—distributing the lift across the airframe from several points makes sense. 

From a literal standpoint, many examples of this concept jostled for attention on the static display and in the halls at the Paris Air Show at Le Bourget this year. But the distributed power demonstrated by CORAC-supported collaboration between major aerospace OEMs Daher, Safran, and Airbus on the EcoPulse project has also emerged as a theme in the drive toward a market-ready airplane.
