Toulouse-based Beyond Aero has sharpened its focus on certification with a refined design for its hydrogen-electric light jet, the BYA-1. The company's latest updates focus on improving safety, efficiency, and operational feasibility of the jet.
The BYA-1, initially unveiled in 2023, is an eight-passenger business aircraft designed to run on gaseous hydrogen without batteries. Its propulsion system has been updated to include two independent power channels, reducing the risk of failure while increasing redundancy.
The fuel cell stack has been upgraded to 2.4MW, while the 700-bar hydrogen tanks have been repositioned above the wing box structure to improve crashworthiness and remove high-pressure fuel lines from the cabin. The aircraft's propulsion system has also been fine-tuned with electric ducted fans and a digital engine control system to optimise performance across all flight phases.
Beyond Aero estimates these refinements will significantly cut costs. Maintenance expenses are expected to be up to 55% lower than those of conventional turbine-powered aircraft due to fewer moving parts, while hydrogen fuel is projected to be 65% cheaper than synthetic sustainable aviation fuel by 2025...more
