EASA Certifies Safran ENGINeUS 100 Electric Motor for Aircraft

EASA Certifies Safran ENGINeUS Motor for Electric Aircraft

The certification of the Safran Engineus 100 electric motor by the European Union Aviation Safety Agency (EASA) marks a pivotal moment in the aviation industry. This milestone is not just a technical achievement but a significant step towards decarbonizing aviation and transitioning to more sustainable propulsion technologies. Historically, aviation has relied heavily on conventional thermal engines, but with increasing concerns about climate change and environmental impact, the industry has been exploring alternative propulsion methods.

In 2017, EASA initiated discussions on regulating innovative propulsion systems, including electric and hybrid-electric engines, to support Urban Air Mobility (UAM) and Regional Air Mobility (RAM). The certification of the Engineus 100 under Special Condition SC E-19, a new regulatory framework developed by EASA, is a testament to the collaborative efforts between regulatory bodies and industry leaders to drive innovation and ensure safety standards are met in emerging technologies.

Certification and Testing

The Safran Engineus 100 electric motor is the first to receive EASA certification for use in hybrid and all-electric aircraft. This certification was achieved after an extensive testing process involving over 1,500 hours of motor testing and more than 100 flight hours under real-world conditions. These rigorous tests ensured the motor’s safety and performance, making it suitable for small electric aircraft like the Diamond Aircraft Industries eDA40, an all-electric training aircraft.

The certification process was not just about testing the motor’s performance but also about ensuring its safety in various scenarios. For instance, the risk of fire in electric engines, which arises from the use of high voltage and electrical arcing, was thoroughly tested. A worst-case scenario was defined and tested, and mitigations were put in place to allow a pilot to land safely if such a scenario arose. This level of scrutiny and collaboration between Safran and EASA sets a high standard for future certifications in the industry.

“We have just witnessed a key moment in the history of aviation. By obtaining certification for the Engineus 100 electric motor, Safran has achieved a world first. This event represents an immense source of pride,” said Bruno Bellanger, CEO of Safran Electrical and Power.

Design and Production

The Engineus 100 electric motor features several innovative design elements that set it apart from conventional engines. It integrates power and control electronics directly into the motor, enhancing its compactness, lightness, and efficient air cooling. This integration allows for easy incorporation into various propulsion architectures, making it versatile for different aircraft designs.

Safran plans to produce more than 1,000 Engineus motors a year by 2026, using four semi-automated production lines in Niort, France, and Pitstone, UK. These facilities will be equipped with space to increase production, reflecting the growing demand for electric propulsion systems in the aviation industry. The initial B1 model, which has been certified, is suitable for installation on two-seater light aircraft. However, Safran aims to extend the series to a greater power range of 89 KW to 180 KW, which would allow for wider applications in up to 19-seater regional transport aircraft.

According to Safran, the motor could also be used for the electric hybridization of future generations of commercial aircraft engines, capable of carrying 150 passengers. This potential for scalability and adaptability makes the Engineus 100 a cornerstone in the future of sustainable aviation.

Industry Adoption and Future Implications

The certification of the Engineus 100 has already garnered significant interest from aircraft developers. Companies like Aura Aero, Bye Aerospace, CAE, Electra, TCab Tech, and VoltAero have selected the Engineus motor for their new air mobility projects. This widespread adoption indicates a strong industry interest in electric propulsion technologies and a shift towards more sustainable aviation solutions.

This milestone also underscores the collaborative efforts between regulatory bodies like EASA and industry leaders like Safran to drive innovation and ensure safety standards are met in emerging technologies. As the demand for sustainable aviation solutions grows, the certification of the Engineus 100 sets a crucial precedent for future developments in electric and hybrid-electric aircraft propulsion. The aviation industry’s shift towards electric and hybrid-electric propulsion systems could have far-reaching implications, including reduced operating costs, lower noise levels, and enhanced environmental sustainability.

“This achievement is paving the way for the electrification of aviation, from small airplanes and beyond. This was a fascinating project for EASA, and the first test of our Special Condition designed for the certification of hybrid and all-electric propulsion,” said Rachel Daeschler, EASA’s certification director.

Conclusion

The certification of the Safran Engineus 100 electric motor by EASA is a landmark achievement in the aviation industry. It represents a significant step towards decarbonizing aviation and transitioning to more sustainable propulsion technologies. The extensive testing and innovative design of the Engineus 100 ensure its safety and performance, making it a versatile and scalable solution for various aircraft designs.

As the aviation industry continues to explore alternative propulsion methods, the Engineus 100 sets a high standard for future certifications and developments. The widespread adoption of this motor by leading aircraft developers indicates a strong industry interest in electric propulsion technologies. This milestone not only underscores the collaborative efforts between regulatory bodies and industry leaders but also paves the way for a more sustainable future in aviation.
