Lilium has invented a completely new aircraft concept for the modern age. While vertical take-off and landing (VTOL) itself is not new – after all, quadcopters, tilt rotors and tilt wings are well-known concepts – they did not want to accept the compromises inherent to these configurations.
Quadcopters excel with their simplicity but are highly inefficient in cruise flight. Transition aircraft can fly three times faster and ten times further with an equally sized battery, but system complexity is usually much higher.
The Lilium Jet consists of a rigid winged body with 12 flaps. Each one carries three electric jet engines. Depending on the flight mode, the flaps tilt from a vertical into a horizontal position. At take-off, all flaps are tilted vertical, so that the engines can lift the aircraft. Once airborne, the flaps gradually tilt into a horizontal position, leading the aircraft to accelerate. When they have reached complete horizontal position, all lift necessary
