Beyond Aero has replaced the electric ducted fans on its BYA-1 hydrogen fuel cell aircraft with pusher-configured propfans, confirmed by a preliminary design review. The maximum take-off weight has been increased to 9.6t, placing it in the CS-25 certification category.

The aircraft is designed to accommodate six passengers for 800nm flights. The pusher configuration aids in noise reduction and optimizes fuel consumption. Beyond is currently assessing heat exchanger technologies for improved performance. A critical design review is scheduled in 12-18 months, with the first flight planned for 2029 and certification in 2030.
