Key Takeaways:

Beyond Aero, a French company, is developing the BYA-1, a hydrogen-electric light business jet with a target introduction around 2030.
They recently completed inaugural wind tunnel tests on a one-eighth scale prototype, which validated the predicted performance and aerodynamics of its unique external hydrogen tank design.
The aircraft's innovative architecture features external 700-bar gaseous hydrogen fuel tanks for enhanced crashworthiness, preserved cabin space, and safe venting.
Beyond Aero is progressing towards formal EASA certification, with its hybrid propulsion system having achieved Technology Readiness Level 6.

A French company developing what it bills as the first hydrogen-electric light business jet is starting to put its unique architecture through experimental testing.

Beyond Aero—developer of the BYA-1, which it aims to introduce around 2030—on Monday revealed that it completed an inaugural wind tunnel test campaign using a one-eighth scale prototype. The company told FLYING it is nearing the final stage of its preliminary design phase, during which it will freeze the design. After that, it will begin formal certification efforts with the European Union Aviation Safety Agency (EASA).
