French startup Beyond Aero has completed the Preliminary Design Review (PDR) for its BYA-1 hydrogen-electric business jet, advancing toward certification under CS-25 regulations while refining its propulsion design. The company, founded in 2020 and based at Toulouse-Francazal Airport, targets first delivery by 2030.
The BYA-1 features a battery-free hydrogen fuel cell system delivering 2.4 MW to two electric engines, enabling a 1,500 km (800 NM) range at 573 km/h (356 mph) cruising speed in a six-passenger configuration. Gaseous hydrogen tanks at 700 bar integrate into the wingbox above the structure, enhancing crashworthiness by avoiding high-pressure lines in the pressurized cabin. Operational flexibility includes a 620 m takeoff ground roll and 5.5° approach angle, suiting constrained airports like London City.
Recent refinements shift from electric ducted fans to pusher propellers for improved efficiency, paired with an advanced thermal management system and custom FADEC. Beyond Aero reached Technology Readiness Level 6 (TRL6) via full-scale propulsion tests, validated with partners including EKPO Fuel Cell Technologies, whose NM20 stack achieves 57% efficiency. The firm acquired Universal Hydrogen’s patents and assets, bolstering development.
Certification progresses through EASA collaboration, with Design Organization Approval applied in April 2024. Beyond Aero completed its first wind tunnel campaign on a scale model, testing up to 288 km/h to validate hydrogen tank aerodynamics. Letters of intent cover 72 aircraft worth $580 million; the team exceeds 70 engineers, recruiting 30 more.
