Germany's Lilium has started "milestone" wind tunnel testing of its electric vertical take-off and landing (eVTOL) Lilium Jet model.
The work, using a scale model of the aircraft, is being done at German-Dutch Wind Tunnels (DNW) in Marknesse in the Netherlands, which Lilium said is Euro-pe's biggest such facility.
The testing "will enable Lilium to obtain a comprehensive aerodynamic dataset to validate its flight physics and performance predictions", the company said.
"We look forward to generating vast amounts of aerodynamics data on the aircraft and building further confidence in our design tools as we prepare for the start of final assembly later this year," said Alastair McIntosh, the company's chief technology officer,.
