Doroni Aerospace Partners With TLG Aerospace on H1‑X Engineering and Certification

Doroni Aero­space has part­nered with Seat­tle-based aero­space engi­neer­ing firm TLG Aero­space to sup­port engi­neer­ing analy­sis and cer­ti­fi­ca­tion work for its H1‑X per­son­al elec­tric ver­ti­cal take-off and land­ing air­craft.

Under the part­ner­ship, TLG Aero­space will work with Doroni’s engi­neer­ing team on the H1‑X’s vehi­cle design, struc­tur­al loads analy­sis, finite ele­ment analy­sis (FEA), com­pu­ta­tion­al flu­id dynam­ics (CFD) and flight mechan­ics. The work is intend­ed to sup­port the aircraft’s pro­gres­sion towards full-scale pro­duc­tion, ground test­ing and FAA air­wor­thi­ness require­ments.

The H1‑X is being devel­oped as a per­son­al eVTOL with a tan­dem-wing con­fig­u­ra­tion and enclosed duct­ed-fan propul­sion. Doroni says the air­craft is designed to accom­mo­date res­i­den­tial garage stor­age and per­son­al flight oper­a­tions. The com­pa­ny is also devel­op­ing a dig­i­tal co-pilot sys­tem for the air­craft.

A major focus of the col­lab­o­ra­tion will be estab­lish­ing engi­neer­ing data to sup­port the H1‑X’s planned cer­ti­fi­ca­tion path­way under the FAA’s MOSAIC reg­u­la­to­ry frame­work. TLG Aero­space has FAA Des­ig­nat­ed Engi­neer­ing Rep­re­sen­ta­tives with exper­tise in areas includ­ing flight per­for­mance and han­dling qual­i­ties, loads, struc­tures and aero­elas­tic­i­ty.

The com­pa­nies will use struc­tur­al and aero­dy­nam­ic analy­sis to assess the H1‑X before major phys­i­cal build and test­ing activ­i­ties. Struc­tur­al work will include air­frame loads mod­el­ling and finite ele­ment analy­sis, with the aim of eval­u­at­ing the strength and weight char­ac­ter­is­tics of the aircraft’s car­bon-fibre struc­ture.

Aero­dy­nam­ic analy­sis will use CFD to exam­ine per­for­mance across dif­fer­ent flight regimes, includ­ing hov­er and for­ward flight. The com­pa­nies also plan to assess tran­si­tion char­ac­ter­is­tics and ener­gy con­sump­tion as the air­craft moves between ver­ti­cal and wing-borne flight.

The part­ner­ship will addi­tion­al­ly cov­er prepa­ra­tion of engi­neer­ing datasets, stress reports and test plans intend­ed to align with applic­a­ble con­sen­sus stan­dards under the MOSAIC frame­work.

Doroni said the col­lab­o­ra­tion will sup­port the com­pa­ny as it moves towards advanced flight test­ing and pro­duc­tion devel­op­ment. TLG Aero­space will pro­vide engi­neer­ing and cer­ti­fi­ca­tion sup­port from its Seat­tle oper­a­tion, where it works on air­craft pro­grammes from ear­ly-stage devel­op­ment through flight cer­ti­fi­ca­tion.
