The researchers are confident that their work will lead to the design of embedded engines that not only sound quieter but are also quiet when measured.
“By linking turbulent flow ingestion patterns to how people perceive noise, we are giving engineers the tools to design future aircraft that truly sound as quiet as they look,” added Ahmed in the press release.
The efforts are crucial in light of the European Union’s mandate to reduce aircraft noise by 65 percent by 2050. The researchers believe that their work will aid in design of quieter aircraft to be used for large scale air transport as well as for electric vertical take-off and landing (eVTOL) aircraft in the urban air mobility (UAM) sector.
