Most modern gasoline and diesel-powered engines found in the cars and trucks seen on today's roadways rely on the four-cycle-engine principles developed in the late 1800s by Nikolaus Otto, Gottlieb ...

I've never looked at a rocket engine and thought "well that's dull", but this design makes all the others look positively pedestrian. That's because, rather than the traditional process of countless ...

The internal combustion engine, despite being a century-and-a-half old, is still an impressive marvel of engineering. There are several variations of engine design that have been experimented with ...

Rolls-Royce has announced that its new F130 engine has successfully passed the Critical Design Review (CDR) phase, progressing toward production. Rolls-Royce has successfully completed F130 engine ...

Alpha-Otto has a design that aims to eliminate all of those drawbacks. The RevForce engine introduces a single, transformative change to the conventional two-stroke layout that preserves its benefits ...

A Norwegian start-up is hoping its small electric-powered ducted-fan engine for unmanned air vehicles (UAVs) can spearhead a move up the weight class into commercial aviation applications.

Variable cycle engine design embodies a transformative approach in aero‐propulsion, enabling engines to adapt their thermodynamic cycle to meet diverse operational demands, from fuel efficiency to ...

The race to field reusable hypersonic aircraft got a whole lot hotter last month, with GE Aerospace announcing a breakthrough in high-speed jet engine design that could potentially allow conventional ...
