Lilium GmbH

An Electric Personal Jet Capable Vertical Take-off and Landing


Lilium is developing, building, and selling a two-seated electric jet capable of vertical take-off and landing (VTOL). The company was founded in February 2015 by four engineers and Ph.D students from Technische Universität München. Lilium has developed an entirely new aircraft concept for vertical take-off (patent pending) that opens the door to a new class of simpler, safer, quieter, and more enduring VTOL aircraft. It has validated the concept with several scaled prototypes weighing 25 kg, and is now developing its first product: a two-seated ultralight VTOL jet. Lilium has a highly diversified team of experts in fields ranging from aerodynamics, flight control, and CFRP structures to electric propulsion and product design. Together, its members are developing aircraft designed for use in everyday life.


Today, aviation consists almost entirely of two types of aircraft: helicopters and airplanes. Airplanes are very efficient, fast, available in any size, and equipped with safety redundancies for flaps, engines, and other crucial components. Their main disadvantages are their need for large runways and their high take-off noise, which have led to airports being located 20-50 km outside of cities. Airports are expensive bottlenecks in the transportation chain; especially in the case of short-haul flights, travel time to and from the airport can easily double the duration of a trip. This is not a problem for helicopters, which can take off almost anywhere. However, helicopters are slow and inefficient in comparison to airplanes. Since they are the only aircraft type capable of true door-to-door transport, they are well established in short shuttle flights and special applications. That said, helicopters require complex and expensive licences, have no backup solution in case of rotor failure, and are very demanding and expensive in terms of construction and maintenance. In addition, they emit so much noise during take-off that permission to operate a helicopter pad is usually denied in urban areas.
The Lilium Jet merges the benefits of helicopters and airplanes while avoiding their drawbacks. It can take off vertically and hover like a helicopter, but also functions like a very efficient airplane that can travel at speeds up to 450 km/h. Meanwhile, it is entirely electric and emits little noise during take-off in comparison to helicopters thanks to its ducted fan engines. Its batteries, engines, and controllers are redundant, making the Lilium Jet a much safer concept than conventional helicopters.
Since more than 70% of all deadly accidents in aviation occur during take-off and landing on runways, computer-assisted vertical take-off is essential for an aircraft that targets the consumer market as means of individual transportation.
The Lilium Jet’s high efficiency in cruising mode enables it to consume half the energy of an electric car and gives it an all-electric range of 500 km. It is positioned as a premium means of individual transportation with convenient and elegant product design. The jet features a side-by-side cockpit, touchscreen and fly-by-wire joystick controls, retractable landing gear, wing doors, a large boot, automatically folding wings, panoramic windows, and a battery that can be recharged using any wall plug.

From space to industry

The aircraft and its components are solely based on R&D by Lilium and its development partners. The main space technologies involved are airborne GPS navigation systems and lightweight materials like CFRP. GPS navigation is crucial to the aircraft’s high degree of automation and wind and drift compensation during vertical take-off and landing.
