Honeywell Develops “Innovative, Custom-Built Lightweight Sensor Technology for Lilium Jet”
Honeywell announced this week the development of an innovative, custom-built, lightweight sensor for the Lilium Jet, reports a press release. After being selected by Lilium to supply propulsion unit position sensors, Honeywell has designed “resolvers,” specifically for the needs of the Jet.
These sensors play a critical role in accurately sensing the engine’s position, ensuring that the Jet can safely reach the exact position required for a successful takeoff.
Creating such solutions for regional air mobility, supports Honeywell’s portfolio alignment to three compelling megatrends:-
: Automation.
: The future of aviation.
: Energy transition.
Honeywell is also an investor in Lilium and supplies many key components for the Lilium Jet, including e‑motors for the engines, avionics, onboard thermal management systems and the flight control computer.

Yves Yemsi, COO at Lilium, commented, “Honeywell’s expertise in both the aerospace and sensing industries means they are able to understand the unique needs and create tailored solutions for the Lilium Jet.” He continued, “In rethinking the traditional resolver, Honeywell is playing a key role in turning our concept, a fully-electric jet that takes off and lands vertically, into a reality.”
The release states, “The Lilium Jet is powered by 30 electric ducted fan engines, each of which need to move precisely from a vertical to horizontal position to support takeoff and forward movement in the air. This action is controlled by a resolver, traditionally a heavier piece of equipment composed of coils of copper wire and magnetic steel.”
The release continues, “The resolver is substantially less expensive and lighter-weight than traditional counterparts. Although specific to the Lilium Jet, this Honeywell-patented technology can be replicated across other types of electric aircraft and will play an important role in furthering the adoption of advanced air mobility.”

Sarah Martin, President of Honeywell Sensing Solutions, remarked, “A growing number of eVTOLs will be flying above us in the very near future, representing a groundbreaking step in the electrification of air transport. Our sensors, though small, are playing a large part in making these aircraft a reality.”
