Silent flight edges closer to reality, new research suggests

Researchers at the University of Bristol have uncovered the secrets behind the quiet operation of futuristic aircraft equipped with innovative embedded engines.

“Our study addresses this urgent issue of noise, which poses a major obstacle in obtaining certifications, by uncovering the physics behind the noise these configurations produce. By understanding the noise mechanisms in BLI ducted fans, it is hoped that industrial guidelines can be developed for quieter airframe-integrated propulsion systems in future aircraft concepts, from large-scale conventional aircraft to small-scale electric vertical take-off and landing, known as eVTOL, aircraft.

Earlier studies on BLI configurations primarily concentrated on fans lacking ducts, which interact with the boundary layer over flat airframe surfaces. “With the growing demand for a pleasant flight experience with minimum environmental impact, there is a need for quieter aircraft. This research has potential applications in developing strategies to reduce noise emission in the aviation sector,” he highlighted. This study, funded by the European Union’s Horizon 2020 research and innovation program under the ENODISE initiative, represents a significant step forward in understanding the complexities of boundary layer ingesting ducted fans.
