Diamond Aircraft Industries GmbH in collaboration with Siemens AG has flown a multi-engine hybrid-electric aircraft at Diamond’s headquarters in Wiener Neustadt, Austria, a milestone that the lightplane manufacturer says will help keep the future of flying sustainable.
Diamond Flies Multi-Engine Hybrid-Electric Prototype
Key Takeaways:
- Diamond Aircraft and Siemens AG successfully completed the maiden flight of a multi-engine serial-hybrid electric aircraft (a reconfigured DA40), marking a significant milestone for sustainable aviation.
- The aircraft employs a serial-hybrid powertrain where a diesel combustion engine powers two independent electric motors, enabling reduced fuel consumption, lower noise emissions, and full electric takeoffs.
- This demonstrator is the world's first serial-hybrid electric plane with two electrically powered free-stream propellers and one combustion engine, showcasing a distributed propulsion architecture that promises enhanced safety and new possibilities for aircraft design.
