Doroni Aerospace has partnered with TLG Aerospace to advance engineering and certification preparation for its H1-X personal electric vertical take-off and landing (eVTOL) aircraft. Announced on September 29, 2026, the collaboration includes structural loads analysis, finite element analysis (FEA), computational fluid dynamics (CFD), and flight mechanics work focused on the aircraft’s development and airworthiness requirements.
The H1-X features a tandem-wing configuration and fully enclosed ducted-fan propulsion. Its airframe uses carbon fiber, making structural performance and weight management important considerations as the design progresses. Under the partnership, the engineering teams will model airframe loads and assess structural integrity to help balance strength with payload capacity.
Finite element analysis will support the assessment of structural stresses and loads across the aircraft, while computational fluid dynamics will be used to evaluate aerodynamic performance. The work will examine hover lift, cruise aerodynamics, transition between flight modes, and energy consumption across operating conditions. These analyses are intended to refine the design before major physical build and testing phases.
TLG Aerospace will also contribute certification engineering through its team of FAA Designated Engineering Representatives (DERs), with expertise in flight performance, handling qualities, structural loads, stress analysis, and aeroelasticity. The partnership will help organize engineering data, stress reports, and test plans to support alignment with applicable consensus standards under the FAA’s MOSAIC framework.
For the composite airframe, the analysis is intended to establish confidence in the structure’s strength-to-weight performance before physical testing. This is particularly relevant to eVTOL platforms, where airframe mass, payload capability, and the demands of vertical and forward flight must be considered together. The announcement does not disclose the specific carbon-fiber grades, resin system, laminate architecture, or manufacturing process used for the H1-X.
The collaboration is intended to move the H1-X toward ground testing, further flight development, and eventual production. Doroni has previously indicated that customer deliveries are targeted to begin by 2028, although this remains a company projection rather than a confirmed certification or delivery milestone.
