Beyond Aero Validates Hydrogen Business Jet Aerodynamics in Wind Tunnel Tests
Beyond Aero completes wind tunnel tests for its hydrogen-powered business jet, confirming aerodynamic stability and advancing propulsion readiness.
Wind Tunnel Success Marks Milestone for Hydrogen Business Aviation
On January 19, 2026, Toulouse-based manufacturers Beyond Aero announced the successful completion of a critical wind tunnel test campaign for its “One” (BYA-1) business jet. The testing, conducted at the German-Dutch Wind Tunnels (DNW) facility in Marknesse, Netherlands, serves as a primary validation of the aircraft’s novel aerodynamic architecture, specifically the integration of external hydrogen fuel tanks.
The campaign utilized a 1:8 scale model of the aircraft and spanned five weeks, generating over 60,000 data points. According to the company, these tests confirmed the stability and control of the design, validating the Computational Fluid Dynamics (CFD) models used during the preliminary engineering phase. This milestone keeps the program on track for a targeted entry into service in the early 2030s.
Validating the “One” Architecture
The primary engineering challenge addressed during this campaign was the aerodynamic impact of gaseous hydrogen storage. Unlike traditional jet fuel, which is stored in wings, hydrogen requires high-pressure tanks that occupy significant volume. Beyond Aero’s design places these tanks in fairings external to the pressurized fuselage, a configuration that frees up cabin space but introduces complex airflow considerations.
In the company’s press statement, the engineering team highlighted the necessity of this testing phase:
“Validating a hydrogen-driven aerodynamic architecture… Hydrogen propulsion introduces architectural constraints that fundamentally shape aircraft aerodynamics.”
The tests at DNW’s Low-Speed Facility (LST) focused on the interaction between the fuselage, wings, and these external nacelles. The data reportedly confirms that the aircraft maintains necessary lift and stability characteristics despite the structural modifications required for hydrogen propulsion.
Aircraft Specifications and Performance
The “One” is designed as a mid-size business jet falling under the CS-23 certification category. Based on the specifications released by Beyond Aero, the aircraft targets the following performance metrics:
- Range: 800 nautical miles (approx. 1,500 km), covering roughly 80% of typical business aviation missions.
- Capacity: 6 to 8 passengers.
- Speed: Cruise speed of 310 knots (approx. 575 km/h).
- Propulsion: A 1.2 MW hydrogen-electric powertrain consisting of two 600 kW electric-aviation ducted fans.
The powertrain relies on gaseous hydrogen stored at 700 bar. The company expects to reach a design freeze by early 2027.
Strategic Acceleration via Acquisition
While the wind tunnel tests validate the airframe, Beyond Aero has also accelerated its powertrain development through strategic asset acquisitions. Following the 2024 cessation of operations by Universal Hydrogen, Beyond Aero acquired that company’s patent portfolio, flight test data, and test benches.
This acquisition allowed Beyond Aero to bypass several years of research and development. In October 2025, the company announced it had achieved Technology Readiness Level 6 (TRL 6) for its propulsion system, a milestone significantly aided by the integration of the former Universal Hydrogen assets.
AirPro News Analysis
The successful wind tunnel campaign by Beyond Aero highlights a diverging path in the hydrogen aviation sector. While competitors like ZeroAvia have focused on retrofitting existing airframes (such as the Cessna Caravan or Dash 8) to expedite certification, Beyond Aero is pursuing a “clean-sheet” design. This approach allows for optimized integration of hydrogen tanks, arguably the most difficult physical constraint of hydrogen aviation, but it carries the higher capital risk and longer timelines associated with certifying a brand-new airframe.
Furthermore, the regulatory landscape remains a significant hurdle. The “One” is set to be certified under EASA CS-23 regulations, but current standards do not explicitly cover hydrogen electric propulsion. Beyond Aero’s “Pre-Application Contract” (PAC) with EASA suggests they are positioning themselves as a regulatory pathfinder, helping to define the “Special Conditions” required for future hydrogen aircraft. The successful aerodynamic validation of external tanks is a crucial step in proving to regulators that hydrogen infrastructure can be safely integrated into a certified airframe without compromising flight characteristics.
