Towards the future of electric and hybrid-electric aircraft

Future tests

Noise emission assessment is essential for designing future aircraft, choosing vertiport locations and flight paths, and informing vital regulation and certification. That’s why we create vehicle source noise profiles alongside leading research centers, providing human impact data before manufacturers are able to release their official noise data.

Electrification will only thrive if communities understand its implications for their environment. We’ve created robust, calibrated sound demonstrations, along with 3D visualizations, that allow people to hear, see, and understand the impacts of Advanced Air Mobility (AAM) networks. Through this, we can present information that has an objective, fact-based approach to community engagement – ​​encouraging informed judgments based on defensible science.

Because AAM vehicles are a new source of noise, studies like ours are needed to generate evidence that can inform more robust certification, including the human response to noise from these vehicles. To this end, Arup and Cranfield are pursuing three major parallel lines of study:

The development of mature paradigms for Part 23 certification and operational approvals of hybrid-electric aircraft.

Investigating the financial and environmental implications of operating electric and hybrid-electric aircraft in various configurations for airlines.

Energy optimization analysis for supporting infrastructure required by electric and hybrid-electric commercial aircraft.

Our research is an important step towards the sustainable decarbonization of the aviation industry and the cities in which it operates. By understanding the sound, environmental and experiential impact of electric aircraft, we can create certification that ushers in an electric transformation with real benefits for the environment and people living near AAMs.
