For the first time, scientists have tested an experimental rocket engine that they say could change the way we launch spacecraft.

The engine, called a rotating detonation rocket engine, propels itself through a continuous series of powerful explosions, according to a University of Central Florida press release. Based on what the researchers found, they say it could make rockets both lighter and more environmentally-friendly.

The trick is to constantly and precisely inject hydrogen and oxygen gas into the engine so that there’s always more fuel to burn when the swirling explosion comes back around, according to new research published in the journal Combustion and Flame — a tough job, because the explosion travels at five times the speed of sound.

Oh, let's add this from February, ... eaper.html
"The rotating detonation engine field is still in its infancy. We have tons of data about these engines, but we don't understand what is going on," said lead author James Koch, a UW doctoral student in aeronautics and astronautics. "I tried to recast our results by looking at pattern formations instead of asking an engineering question—such as how to get the highest performing engine—and then boom, it turned out that it works."
