Anyone who has lived near an airport can attest that airplane engines are loud. If you've ever lived near a military air base, you know that fighter jets can have some of the loudest. The turbulence ...

The biggest concern for Boeing was that, while chevrons were certainly effective at lowering engine noise, they also had the ...

You may have noticed them on certain planes when looking out the terminal windows — a kind of shark-toothed look on the back of some planes' engines. Commercial airplanes, outside of their livery, are ...

Jet noise and turbulent flow dynamics remain at the forefront of fluid dynamics research, addressing both the fundamental physics of turbulence and its practical implications for noise control in ...

Jet noise prediction has long posed a significant challenge in aerospace engineering, with large eddy simulation (LES) emerging as a powerful tool to elucidate the complex interactions between ...

DOE supercomputers will simulate the in-flight performance of a GE Aerospace open-fan concept engine, to evaluate its energy-efficiency and noise levels. The CFM International Open Fan concept jet ...
