Experimental study of realistic low noise technologies applied to a full scale nose landing gear
Bennett, Gareth; Kennedy, John (2021)The landing gear system is the dominant airframe noise source for most modern commercial aircraft during approach. This manuscript reports the results from the ALLEGRA (Advanced Low Noise Landing (Main and Nose) Gear for ... -
The Impact of Additive Manufacturing on the Acoustic Performance of Novel Porous Materials
Ciochon, Agnieszka Helena; Kennedy, John (2022)Commonly used conventional acoustic porous materials suffer from a limited operational frequency range and great dependency of the sample thickness on their performance. For this reason, acoustic metamaterials have caught ... -
The influence of additive manufacturing processes on the performance of a periodic acoustic metamaterial
Kennedy, John; Trimble, Daniel (2019)Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at the appropriate microscopic scale and sample sizes. The repeatability of the fundamental cell unit of these metamaterials ... -

The influence of chevrons on the turbulent characteristics of jets
Kennedy, John (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2010)To minimize the significant environmental impact of air travel a reduction in noise pollution from jet engines is required. This has led to a renewed focus on active and passive techniques which modify the turbulence ...
