Doroni Aerospace taps TLG Aerospace to speed H1-X certification work

Doroni Aerospace has partnered with Seattle-based TLG Aerospace to advance engineering, testing and certification work on the H1-X personal eVTOL. The collaboration is aimed at helping the flying car startup move faster toward production and FAA airworthiness alignment under the MOSAIC framework.

Why it matters: - The partnership gives Doroni Aerospace access to specialized engineering and certification support as the company works to move the H1-X from concept to production. - The collaboration is meant to strengthen the H1-X’s technical case before major build phases and help narrow the path to FAA airworthiness alignment. - The project also reflects growing pressure on eVTOL developers to prove structural, aerodynamic and regulatory readiness at the same time.

What happened: - Doroni Aerospace announced a strategic engineering partnership with TLG Aerospace, LLC on September 29, 2026. - Doroni Aerospace is based in Dania Beach, Florida. - TLG Aerospace is based in Seattle, Washington. - The agreement is designed to accelerate the H1-X toward full-scale production, ground testing and FAA airworthiness alignment. - Doroni said the H1-X is designed for residential garage integration and everyday personal flight.

The details: - The H1-X uses a tandem wing architecture, fully enclosed ducted fan propulsion and the proprietary SOUL AI™ digital co-pilot system. - TLG Aerospace will work with Doroni’s internal engineering team on full-vehicle design, structural loads analysis, finite element analysis, high-fidelity computational fluid dynamics and flight mechanics. - TLG Aerospace also brings in-house FAA Designated Engineering Representatives, or DERs, focused on flight performance, handling qualities, loads, structures and aeroelasticity. - The partners say the effort will support certification work under the MOSAIC regulatory framework and consensus standards. - The engineering work is intended to validate the H1-X airframe’s strength-to-weight ratio and transition-flight physics before larger physical builds. - Doroni says the H1-X uses a carbon-fiber airframe. - The collaboration’s focus areas include configuration engineering, structural integrity and airframe loads, aerodynamic and transition efficiency, and compliance and DER support. - In the compliance work, the teams will structure engineering datasets, stress reports and test plans to align with FAA MOSAIC standards. - Doroni was founded in 2016 by entrepreneur Doron Merdinger. - Doroni’s website is the company’s website. - TLG Aerospace specializes in aerodynamics, structural loads, flutter analysis, stress engineering and flight test support. - TLG’s website is the company’s website.

Between the lines: - The partnership suggests Doroni is leaning on outside certification expertise to reduce risk in areas that can slow advanced air mobility programs. - Bringing in DER-level analysis early can help identify design issues before they become expensive rework. - The MOSAIC reference shows Doroni is positioning the H1-X for a certification path tied to emerging consensus-based standards, not just vehicle performance. - The collaboration also signals that the H1-X is still in the engineering-validation stage rather than commercial deployment.

What's next: - Doroni and TLG Aerospace will continue joint engineering work on the H1-X across design, loads, CFD and certification documentation. - The teams are expected to use the analysis to support ground testing and future flight-testing milestones. - Doroni says the work is intended to prepare the H1-X for market.

The bottom line: - Doroni is pairing its vehicle design with TLG Aerospace’s certification and analysis depth to move the H1-X closer to the testing and regulatory milestones it needs for commercialization.
