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 flew a multi-engine serial-hybrid electric aircraft, a reconfigured DA40, marking a significant step towards sustainable aviation.
- The aircraft utilizes a serial-hybrid system where a single combustion engine acts as a generator for two independent electric drive systems, enabling pure electric takeoffs, reduced noise, and improved fuel efficiency.
- This pioneering project demonstrates a distributed propulsion architecture with redundant electric motors, offering enhanced safety, flexibility for future aircraft designs, and extended flight capabilities (30 mins pure electric, 5 hours hybrid).
