Beyond Aero BYA-1 business jet
Beyond Aero’s BYA-1 business jet will be powered by a hydrogen-electric propulsion system for which the company has recently achieved TRL6.

Beyond Aero has reported that it has achieved technology readiness level 6 (TRL6) with the hydrogen-electric propulsion system it is developing for its planned BYA-1 business jet. On October 1, the French start-up said it had demonstrated a full-scale example of the powertrain at its headquarters in Toulouse.

According to Beyond Aero, it will now continue to optimize the propulsion system as work continues with the preliminary design review for the eight-seat model, which it aims to bring to market in 2030. The company declined to say when it expects to complete the preliminary and critical design reviews, or when it will be ready to integrate all the key systems into the first full-scale prototype.
