A pulse detonation engine, or “PDE”, is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. The engine is pulsed because the mixture must be renewed in the ...

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 ...

A new rotating detonation engine could revolutionize rocket launches—if it can be made stable enough. That’s a big “if,” and one that researchers are hoping to explore using a new mathematical model ...

Explosions get you much more bang from your fuel buck than combustion – if your engine can withstand them. NASA believes the rotating detonation engine could be the future of deep space travel, and it ...

A Florida team working with the US Air Force claims that it's built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to ...

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 ...

Scientists at the forefront of hypersonic weapons research in China say they have an unprecedented power solution for aerospace planes. The “revolutionary” air-breathing engine could, in theory, lift ...

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 ...

Since the 1960s engineers around the world have been fiddling with a novel type of jet called a rotating detonation engine (RDE), but it has never got beyond the experimental stage. That could be ...

A report about Chinese scientists successfully testing the world's first oblique detonation engine, powered by standard aviation kerosene, has, expectedly, made waves. But it is necessary to point out ...

A Chinese commercial aerospace company conducted the first test flight of a detonation ramjet engine on Tuesday, designed for an aircraft it says will be able to take passengers from Beijing to New ...
