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 ...

Boeing has implemented Engine chevrons, or serrated chevron ducts, on some of its more recent aircraft designs, a feature that can reduce noise emissions and help aircraft abide by noise regulations.

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 ...

As an experimental Su-27 variant, the Su-27LL-PS tested advanced 2D thrust vectoring for enhanced maneuverability, providing critical insights into supermaneuverable flight dynamics, material ...

There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...

Since the 1950s rocket engineers have toyed with the idea of a novel engine design that could –- in theory –- revolutionize the way we conceive of space travel. The aerospike might sound like a ...

In order to be able to carry heavier payloads through deep space, NASA designed a lightweight rocket engine nozzle made of aluminum that can still withstand the heat of launches. NASA recently tested ...

Philippine Public Utility Vehicle (PUV) drivers can now take part in reducing the country’s greenhouse gas emissions while saving on fuel costs by using a patented fuel engine nozzle developed by a ...
