Beyond Aero has completed its first wind tunnel test campaign at the German-Dutch Wind Tunnels in Marknesse, a significant step in the Preliminary Design phase of its hydrogen-electric aircraft. Conducted over five weeks in autumn 2025, the tests focused on ensuring stable aerodynamic performance with external gaseous hydrogen tanks.

A 1:8 scale model was tested at speeds up to 80 m/s, generating over 60,000 data points to assess performance, stability, and control. The results validated numerical models and confirmed the aerodynamic assumptions associated with the hydrogen architecture, aiding in the design process. Beyond Aero aims to develop an electric business aircraft capable of flying 800 nautical miles, having secured over $50 million in funding, and is a member of the World Economic Forum's First Movers Coalition.
