Hybrid electric flight is one of the pillars towards sustainable aviation. However, bringing on-board electric propulsion significantly increases the electric power levels. This yields thermal and electromagnetic challenges.
The Horizon2020 EASIER project, has developed electromagnetic compatibility (EMC) solutions for power EWIS (electrical wiring interconnection system), power electronics and filtering to mitigate the challenges in electromagnetic emissions. Moreover, two-phase cooling systems have been developed to handle the increased heat dissipations, and thermal modelling and validation of power feeder designs has lead to volume and weight efficient power feeders for hybrid electric aircraft.
This video introduces the main challenges EASIER has tackled, and then focuses on the EMC ground based demonstrator hosted at NLR’s facilities. In these tests, power feeder solutions have been validated by a dedicated ground-based demonstrator with the powertrain of Evektor’s EPOS+ (full electric two-seater).
