Supersonic Jet Noise
The noise from high-performance aircraft jet engine exhausts and launch vehicle plumes is primarily caused by supersonically-convected turbulence. Supersonic jet noise is studied to both understand and model its characteristics, as well as to reduce its impact on structures, people, and the environment. Including an introductory editorial, the 23 articles in this special issue represent a broad snapshot of supersonic noise – including perspectives on the past and insights into the future – through increasingly detailed numerical simulations, realistic laboratory-scale investigations, high-fidelity measurements of full-scale aircraft and rockets, and promising noise reduction technologies.
