Going to need a monster muffler for this one.

Same thing, only different.

Reminds me of a Jerry Pournelle/Niven book named Footfall. No, they drop nuke bombs out of the bottom for propulsion. The same theorized propulsion as Project Orion.

Make sure it wasn’t built by Acme.

Chairman Xi Jinping will probably wait until it is scaled up and operational, why take all the development risk/cost?

A UCF team has produced a continuously firing prototype of a H2/O2 rotating detonation engine, capable of running until the fuel is turned off a feat previously thought impossibleProfessor Kareem Ahmed, University of Central Florida

“The study presents, for the first time, experimental evidence of a safe and functioning hydrogen and oxygen propellant detonation in a rotating detonation rocket engine,” says Kareem Ahmed, an assistant professor in UCF’s Department of Mechanical and Aerospace Engineering who led the research
Any bets how long Kareem will be keeping it secret before Iran just happens to develop the same engine?

So another invention the military lets America’s enemies know they should also focus on.

Detonation releases significantly more energy from significantly less fuel mass than combustion, That does not ring true with me. It might release energy *faster* but it seems unlikely to release *more* energy per kilo of fuel and oxidizer.

Ain’t that what all engines do?

In a piston engine, properly controlled detonation offers more useful energy than combustion. Similarly, in a rotating detonation rocket engine, more energy is produced from the same amount of fuel in the useful form of gas under controlled high pressure than is produced in a conventional rocket engine that relies on combustion. More broadly, whether generated by detonation or combustion, such high-pressure gas can be directed into a rocket exhaust, a power turbine, or an aircraft turbine engine. With enough development work, one can even imagine rotary detonation engines powering more fuel-efficient locomotives, tanks, and cars.

I think that is referred to as nuclear pulse detonation. Jet fuel pulse detonation is said to have been investigated in a secret US black project aircraft.
To: DUMBGRUNT
“In 2012, the Naval Research Laboratory estimated that rotating detonation engines could save the Navy 15-20 percent off a ~US$2-billion annual fuel bill...
With the price of fuel now, they’ll save $382.
Actually, that is an issue when it comes to developing power plants. Here in the Pacific Northwest there have been lots of places where plans have been developed and studies done to develop low environmental impact small water-powered electrical generation.
But they keep getting shelved and they put up a fairly quick and easy natural-gas plant instead as gas is so cheap. And of course they are hoping that gas will stay cheap for the next 8(?) years or whatever.
