Small, ultra-fast, primary and “afterburner” secondary combustion events promise to deliver brake thermal efficiency as high ...

The Solid Fuel Ramjet (SFRJ) and the Hypersonic Dual-Mode Ramjet (DMRJ) are seeing rapid success as the U.S. hikes spending ...

The world of hypersonics is perhaps just as captivating to some people as say space exploration is to others. After all, it's all about going really, really fast through Earth's atmosphere, many times ...

The Hypersonic Dual-Mode Ramjet test, believed to be the first of its kind, exploited rotating detonation combustion technology. General Electric Aerospace announced a successful demonstration of ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

A team of researchers in Florida, working with the United States Air Force, claim to have built and tested an experimental model of a rotating detonation rocket engine. This type of engine uses ...

Liquid-fuelled rocket engine design has largely followed a simple template since the development of the German V-2 rocket in the middle of World War 2. Propellant and oxidizer are mixed in a ...

Currently, the world is facing pressing concerns regarding the future of sustainability for the planet. Internal combustion engines release carbon emissions, which contribute to irreversible climate ...

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 ...

Venus Aerospace's rotating detonation rocket engine (RDRE). Houston, Texas-based Venus Aerospace, a hypersonics pioneer aimed at developing reusable hypersonic flight platforms, recently achieved one ...

Researchers aim to meld the best attributes of both the power-dense two-stroke and the vastly cleaner four-stroke engines.

There probably never was a better time for rocket engine fans to be alive. It's a time when those who have the means can go out and start building the rocket engine of their dreams, while the rest can ...
