Supersonic Jet Noise: Main Sources and Reduction Methodologies
Supersonic Jet Noise: Main Sources and Reduction Methodologies is a scholarly work, published in 2014 in ''Journal of Engineering Science and Technology Review''. The main subjects of the publication include aerospace engineering, Jet noise, takeoff and landing, acoustics, noise pollution, aircraft noise, aeronautics, noise reduction, noise, environmental science, crew, supersonic speed, acoustic metamaterial, takeoff, jet, and engineering. The large velocity ratio and the presence of Shocks in the exhaust plume from low bypass engines or supersonic jetliners cause jet noise to be dominant component of overall aircraft noise, and therefore is an important issue in design of the next generation of civil supersonic transport.Jet noise reduction technology also has application in the design of highperformance tactical aircraft.Jet noise is of particular concern on aircraft carriers where it is necessary for deck crew to be in relatively close proximity to the aircraft at takeoff and landing.In this paper, a brief discussion about supersonic jet noise sources and a review of the main passive technologies employed for the reduction of supersonic jet noise are presented.
