Designed for regional mobility

The Lilium Jet was designed with regional mobility in mind. It balances competing requirements for range, speed and payload while delivering a low noise footprint and the same safety standards as today’s commercial aircraft.

The four wings contribute significantly to the overall efficiency, providing lift to support the weight of the aircraft during horizontal flight, while the ducted design of the 36 electric motors provides a significant efficiency advantage over open rotors by blocking the formation of tip vortices.

How we fly

Simplicity in design

The Lilium Jet has an intrinsically simple design. With 36 single-stage electric motors providing near-instantaneous thrust in almost any direction, control surfaces, such as rudders, ailerons or a tail, aren't required. Neither are the oil circuits and gearboxes you would find in a typical aircraft. This contributes to the Lilium Jet having around the same number of individual parts as a family car, or 1,000 times fewer than a traditional jetliner. As well as making the aircraft simpler and faster to design, it also means less maintenance and less cost once in operation.

Designing for low noise

The Lilium Jet engine has been fully developed in our in-house sound lab where we have used proprietary acoustic modelling software, simulated on high-performance computing clusters, to optimize its design. As well as a customized electric motor, it contains innovative liner technology which means the aircraft will be inaudible from the ground when flying above 400m and will only be as loud as a passing truck while taking off. On the ground, the aircraft will move to and from parking bays using separate electric motors, allowing it to be as quiet as a typical electric car.

Progress

Our current test aircraft is a full-scale technology demonstrator that seeks to prove the design of the Lilium Jet and its technologies. We are using data from its flight test campaign to inform the design of the serial aircraft, which is happening simultaneously, in accordance with the strict aerospace processes and guidelines established by the relevant regulatory authorities, and as followed in all major aerospace OEMs (Original Equipment Manufacturers).
