A touchy subject in aviation circles is the effect of jet engine noise on human nerves and bodies. Some of the airmen hate to mention it; they fear that people who live near jet bases will blame all ...

In this video, you'll see the different types of engines and propulsion systems used for aircraft, my favorite ones: Turbojet ...

University of Cincinnati engineers are working on new jet engine nozzles to reduce noise while maintaining performance.

Whatever other qualities they may possess, jet fighters are not known for their quiet engines. They could soon become considerably less noisy without any loss in performance, though, thanks to a ...

NASA's Glenn Research Center has been an integral part of the nation's mission to reduce aircraft engine noise for over 70 years. The center's journey in quieting jet engines has evolved into a ...

New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds ...

This graphene-based aerogel is the lightest sound insulation material ever manufactured, say researchers at the University of Bath, who have demonstrated its ability to damp down noise by up to 16 ...

A state-of-the-art business jet needs an equally-powerful engine. The Gulfstream G400 is packed with innovations and top-level technology, and the Pratt & Whitney PW812GA new engine will help it also ...

A modern jet engine is a complex mechanical wonder. However, these aren't engines that will just roar into action with the turn of a key or the press of a button. Often, turbine engines will need ...
