Lilium completes tests of electric jet propulsion unit

Lilium completed the first series of tests of its electric jet propulsion unit. For the first time, the electric engines were taken up to maximum thrust on the propulsion unit test bench, representing a landmark achievement on the journey to zero operating emissions flight and an important step towards verifying safety of flight of the Lilium Jet. The tests performed have demonstrated the expected level of performance and reliability, bolstering Lilium’s confidence in the maturity of its electric jet propulsion system. Testing of the propulsion unit, comprising two engines within a propulsion mounting system, was carried out at Lilium’s dedicated propulsion unit test bed, located at Lilium’s headquarters near Munich. The test bed has been designed for aerodynamic and electrical performance evaluation of Lilium’s jet technology. The first test of the propulsion unit follows comprehensive testing of the engine, developed and built in collaboration with Lilium’s team of suppliers, including Denso and Honeywell for the e-motor, Aeronamic for the compressor fan, and SKF for the electric motor bearings.
