Lilium, the German aviation company developing the world’s first all-electric jet capable of vertical takeoff and landing (eVTOL), has closed a $90 million Series B funding round.

The funding group consists of Tencent; LGT, the international private banking and asset management group; Atomico, Lilium’s Series A backer founded by Skype co-founder Niklas Zennström; and Obvious Ventures, whose co-founder Ev Williams is Twitter’s co-founder and former CEO. The investment brings the company’s total capital raised to more than $100 million. Freigeist (formerly e42) were Lilium’s seed investors. The investment will be used for the development of the five-seat Lilium Jet that will fly commercially, as well as to grow the company’s current team of more than 70.

Flight tests of world’s first electric VTOL jet were successful

In April 2017, the first zero-emission eVTOL has completed a series of rigorous flight tests in the skies above Germany. The two-seater prototype executed a range of complex maneuvers, including its signature mid-air transition from hover mode to wing-borne forward flight. Co-founder and CEO Daniel Wiegand  said: “Seeing the Lilium Jet take to the sky and performing sophisticated maneuvers with apparent ease is testament to the skill and perseverance of our amazing team. We have solved some of the toughest engineering challenges in aviation to get to this point. The successful test flight programme shows that our ground-breaking technical design works exactly as we envisioned.”

The company is now developing a larger, five-seater version of the Jet, designed for on-demand air taxi and ridesharing services.

The Lilium Jet is 100% electrically powered, so creates no harmful emissions, making it a potential solution to deteriorating air quality in towns and cities, caused by road traffic. It is also the only electric aircraft capable of both VTOL and jet-powered flight, using its wings for lift, similar to a conventional airplane.

This advanced capability consumes around 90% less energy than drone-style aircraft, enabling the jet to achieve a range of more than 300 km with a maximum cruising speed of 300 km/h. In flight, the Jet’s power consumption per km will be comparable to an electric car. Take-off and landing for a Lilium Jet only requires a small open space or landing pad on a building – alleviating pressure on congested roads.

The combination of energy efficient flight and minimal ground infrastructure will enable passenger flights with comparable pricing to normal car taxis over the same distance. A typical journey by Lilium Jet will be at least 5x faster than by car, with even greater efficiencies in busy cities. For example, a flight from Manhattan to New York’s JFK Airport will take around 5 minutes, compared to 55 minutes driving.

The ability of the Lilium Jet to travel long distances, quickly and at low cost will also open new opportunities for people to live further away from their place of work. Lilium describes this phenomenon as increasing the radius of living by 5x.

How the Lilium Jet Works

The Lilium Jet is a lightweight aircraft powered by 36 electric jet engines mounted to its wings via 12 moveable flaps. It is unique in combining the benefits of VTOL offered by helicopters and drones, with the speed and range of a jet aircraft.

At take-off, the jet’s flaps are pointed downwards to provide vertical lift. Once airborne, the flaps gradually tilt into a horizontal position, providing forward thrust. When the wing flaps are horizontal, all of the lift required to keep the jet in the air is provided by air passing over the wings – as with a conventional airplane.

Safety is of primary concern of Lilium, and the Jet is designed along the principle of Ultra Redundancy: The aircraft’s engines are individually shielded, so the failure of a single unit cannot affect adjacent engines.

The Jet’s power cells are designed to continue delivering sufficient power for continued flight and a safe landing in the unlikely event that part of the battery configuration fails. Lilium’s Flight Envelope Protection System prevents the pilot from performing maneuvers that would take the aircraft beyond safe flight parameters.

About Lilium

Lilium was founded in 2015 by Daniel Wiegand and three fellow-academics from the Technical University of Munich. The group shared a vision of a completely new type of transportation. In less than two years, Lilium has grown from the founding team to a company of more than 40 world-class engineers, developing and building the first fully electric vertical take-off and landing (VTOL) jet. With an estimated range of 300 km, a maximum cruising speed of 300 km/h, and zero emissions, the Lilium Jet will be the most efficient and environmentally friendly means of high speed transportation. With ultra-redundancy by design, the Lilium Jet is also setting new standards in aircraft safety.
