From a thermodynamic point of view, detonations are more efficient than the more commonly known deflagration (classic combustion). While classic combustion in rocket engines takes place at constant ...

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 ...

A new family of engines aims to harness the power of detonation shockwaves to create ever-faster rocket engines. One of these engines—known as a rotating detonation engine (RDE)—has shown some ...

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 ...

For decades, engineers have fought to prevent detonations in rocket engines—now, NASA is using them on purpose. The Rotating Detonation Engine (RDE) is a radical innovation that leverages ...

Venus Aerospace, a leader in hypersonics deep-tech startups aimed at revolutionizing high-speed flight, has successfully achieved ignition of its ‘VDR2’ engine. VDR2 offers a single engine solution ...

Pratt & Whitney is planning further development of rotating detonation engine (RDE) technology following “positive test results” from a series of ground tests. The work, which was completed ...

A new type of rocket engine that could improve aircraft, spacecraft, and other transportation systems is being developed by private and public institutions such as NASA and the Air Force Research ...

Over the years [Integza] has blown up or melted many types of jet engine, including the humble pulsejet. Earlier improvements revolved around pumping in more fuel, or forced air intakes, but now ...

EAST HARTFORD, Conn., March 4, 2025 /PRNewswire/ -- Pratt & Whitney, an RTX (NYSE: RTX) business, has completed a series of tests on its rotating detonation engine (RDE) work with the RTX ...

Rotating Detonation Engines First developed in the 1950s at the University of Michigan, these rocket engines use powerful and chaotic detonations, self-propagating thanks to hypersonic shockwaves ...

Categories include pulse detonation engines, rotating detonation engines and standing wave, or oblique wave detonation engines (OWDEs), and while these are still all at experimental stages, they ...
