Honeywell to Provide Sensors for Lilium's Electric VTOL Jet

Honeywell announced its collaboration with Lilium to supply propulsion unit position sensors for the Lilium Jet. These sensors, known as "resolvers," are tailored to meet the specific requirements of the Lilium Jet, ensuring precise engine position detection for safe takeoff and operation.

The development of these detection solutions aligns with Honeywell's strategy to address automation, future aviation, and energy transition trends. Honeywell, an investor in Lilium, provides various critical components for the Lilium Jet, including electric motors for the propulsion units, avionics, onboard thermal management systems, and the flight control computer.

“Honeywell’s expertise in aerospace and sensor technology enables them to understand the unique needs of the Lilium Jet and develop tailored solutions. By reimagining the traditional resolver, Honeywell is playing a key role in realizing our concept of a fully electric jet with vertical takeoff and landing capabilities,” said Yves Yemsi, CFO, Lilium

Lilium is pioneering the development of the world’s first eVTOL aircraft, aiming to create a high-speed, zero-emission regional transport mode. The Lilium Jet operates with 30 ducted electric fan motors, which must accurately transition from vertical to horizontal positions for takeoff and flight. This motion is controlled by a resolver, which replaces the traditionally heavier components made of copper wire coils and magnetic steel.

In close collaboration with Lilium, Honeywell has developed a custom solid-state resolver using proprietary spiral magnet technology and magnetoresistive sensors to determine magnetic object positions. This resolver is lighter and cheaper than traditional models. Although specifically designed for the Lilium Jet, Honeywell can adapt this technology for other electric aircraft, advancing the adoption of advanced air mobility.

“This expansion of the collaboration between Honeywell and Lilium underscores both companies' commitment to creating solutions for a more sustainable transportation future,” said José Simón, General Manager, Honeywell Industrial Automation for Latin America. “In the near future, we will see more eVTOL aircraft in the skies, and we are proud to be pioneers in the electrification of air transport. Our sensors, though small, play a crucial role in bringing these aircraft to life.”
