Elysian Aircraft has completed the second design iteration of its all-electric E9X regional airliner, passing its Conceptual Design Review and advancing to preliminary design. The update incorporates refinements from years of research, including enhancements to distributed electric propulsion, high-voltage architecture, and modular battery integration within the wing structure.
The company conducted an initial test flight of its Scaled Flight Demonstrator, validating aerodynamic performance, flight controls, and electric propulsion integration. These tests confirm key systems for the E9X program. According to Elysian, industry partners including airlines and suppliers have shown interest in the aircraft and its electrification technologies, which may have broader aerospace applications.
Designed for 88 to 100 passengers, the E9X targets ranges over 750 kilometers initially, with goals to reach 1,000 kilometers as battery energy density improves. The low-wing design features a 42-meter span with foldable wingtips, eight 3.7-meter propellers driven by electric motors, and batteries aiming for 360 Wh/kg density, enabling 30- to 45-minute recharges. Elysian projects energy efficiency up to five times higher than hydrogen or sustainable aviation fuel aircraft per passenger-kilometer.
Partners include KLM, Transavia, Fokker Services, Delft University of Technology, and others. The company is working toward EASA design organization approval and targets certification around 2030, with entry into service by 2033.
