As the automotive propulsion industry shifts toward electrification, the last-of-breed combustion engines are a stultifyingly similar bunch, focused around the same CAD-optimized 500cc cylinder ...

The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

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 ...

With the internal combustion engine (ICE) being a staple of multiple forms of transportation since the late 19th century, most people are at least somewhat familiar with how an engine works: fuel and ...
