Dutch aviation start-up Elysian has revealed its design for one of the largest battery-electric aircraft in the industry, capable of carrying 90 passengers over 500 miles. 

The E9X aircraft, developed in collaboration with the Delft University of Technology, marks a new step in the desire for a sustainable solution for the future of the aviation industry by providing a case for larger battery-electric aircraft which have often not been thought of as a viable option for larger commercial flights. 

Rob Wolleswinkel, co-founder and CEO of Elysian, said: “Contrary to common belief, large battery-electric aircraft can carry much more energy and are aerodynamically more efficient than originally assumed. 

“Instead of a turboprop aircraft, we considered first-generation narrow-body jets as a reference point. While these jets were fuel-inefficient, they were designed for long ranges and carried a high energy mass relative to the total aircraft mass.” 

Elysian’s design for the aircraft is based on research for two scientific papers, “A new perspective on battery-electric aviation, part I and II”, by Wolleswinkel and co-authors Maurics Hoogreef, Roelof Vos, and Reynard de Vries, who also serves as the company’s co-founder and director of design and engineering. 

The next-generation aircraft places the batteries in the wing to “put the load where the lift is” and address the weight issue, which has been seen as one of the main sticking points against creating larger battery-electric aircraft.
