TL;DR: The NASA Glenn Research Center recently completed an experimental study to reduce the jet noise from modern turbofan engines as mentioned in this paper, which concentrated on exhaust nozzle designs for high-bypass-ratio engines.

TL;DR: In this article, the authors demonstrate that modie cations of the core nozzle are generally more advantageous than of the fan nozzle, and demonstrate that the benefits of simultaneous modiecation of both nozzles are greater than those of chevrons.

TL;DR: In this paper, the effect of tabs on a scale model exhaust nozzle system representing low bypass ratio turbo-fan engines was investigated, where both the core and exhaust nozzles were modified, either alone or simultaneously.

TL;DR: In this article, the authors developed a data base on various bypass ratio nozzles, screened quietest configurations and acquired pertinent data for predicting the plume behavior and ultimately its corresponding jet noise.
