Astronics Corporation has been selected by Lilium to design, develop, and build the Lilium Jet’s electrical power distribution system.
Power distribution units play a critical role within the Lilium Jet’s energy management system. Astronics will be responsible for the secondary power distribution units (SPDUs) and charging power distribution units (CPDUs).
Lilium Jets will each be equipped with two SPDUs and one CPDU. SPDUs are responsible for high voltage (1000 VDC) to low voltage (28 VDC) conversion and for low voltage distribution and protection. Compact and light weight, the SPDUs ensure a reliable supply of power from the batteries to the aircraft’s critical systems, including flight controls, avionics, navigation, communication, sensors, internal and external lights, and passenger comfort.
The CPDU manages the battery charging operation, as well as providing additional and dissimilar sources for high voltage to low voltage power conversion and low voltage power distribution, which minimizes common-cause failure modes between the CPDU and SPDU. It also provides an additional layer of aircraft safety by monitoring insulation and detecting and reporting short circuit risks across the system.
Jon Neal, President of Astronics Advanced Electronic Systems, said, “Astronics is thrilled to announce Lilium as a launch customer for our Corepower high voltage products designed for the More Electric Aircraft and eVTOL platforms. This partnership demonstrates the flexibility of our products and our close collaboration with our customers. Astronics is excited to join Lilium in being a part of the evolution of aviation moving towards cleaner, more sustainable, and accessible modes of transportation.”
“Astronics is our ideal partner for this very important component of our aircraft,” said Martin Schuebel, senior vice oresident procurement at Lilium. “It is our intention to collaborate with the best aerospace suppliers and leverage their expertise. Astronics’ expertise is unique, and their collaborative approach makes them a perfect match for us. The partnership will also help pave the way for the coming industrial ramp-up.”
The supplier agreement follows over a year of collaborative work between the two companies and marks a further key milestone in the industrialization of the Lilium Jet.
