NASA and Lockheed Martin are designing an experimental X-plane called the Quiet Supersonic Technology (QueSST) demonstrator aircraft that they hope to fly for the first time in 2019. The program is ...

Jet aircraft are all loud, but few are as loud as the F-18 fighter jet. Researchers from the University of Cincinnati have created a new engine nozzle designed for F-18 fighter planes. According to ...

A variable area nozzle for airliner engine exhausts could reduce noise substantially, according to researchers at the UK's University of Cambridge. Currently used on military engines during ...

A scientists is using ALCF resources to create high fidelity simulations of jet turbulence to determine how and where noise is produced. The results may lead to novel engineering designs that reduce ...

University of Cincinnati doctoral student adjusts a jet engine mounted to the floor of an anechoic chamber to study jet noise. Jet engines can make a symphony of sound from rumbles and roars to ...
