German company lilium has unveiled the design of its 7-seater jet which aims to revolutionize regional travel, saving people hours. The aircraft is capable of vertical take-off, quietly, allowing the company to access plenty landing sites and the opportunity to build higher network density, avoiding expensive ground infrastructure.
The aircraft has cruise speed of 175 mph at 10,000 feet and has a range of 155 miles, including reserves. planned to launch operations in 2024, the aircraft features ducted electric vectored thrust (DEVT). This flight system is integrated into the wing flaps -- electric jet engines provide advantages in payload, aerodynamic efficiency and a lower noise profile, while also providing thrust vector control to maneuver the lilium jet through every phase of flight.
Lilium flies with "electric jets", throwing out a non-combustion compression stream of air. The Lilium's ducted fan is an example of a wider class of ducted propulsor. They all work the same way, to accelerate air in one direction so that the reaction force pushes the fan or propeller in the other. If the blade disc were used to provide compression, the device would not be a propulsor but a compressor and would not exit to the free air stream.
