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 create super-efficient thrust.
While space propulsion is the key driver for this research, it also has potential terrestrial uses in other cases where high power and low fuel consumption could make a big difference. 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 if they were retrofitted in place of the gas turbine engines that run over 100 of its large ships. They could also potentially be used in hypersonic and supersonic flights, or even electric power generation, and Ahmed tells us the design has potential as a booster stage engine as well, but it'd require a different type of propellant.

My favorite line that book:God was a knocking and he wanted in realllllll bad.
Cross between a rocket motor and a scram-jet. Note the “string of diamonds” shockwave in the exhaust.
Jet fuel pulse detonation is said to have been investigated in a secret US black project aircraft.
````
SR-71 used that method I believe I read
LOL! I guess you just don't understand science!
No, it was a claimed SR-71 follow on called Aurora, with a “donuts on a rope contrail” said to be indicative of a pulsed or wave detonation engine. This is now mostly thought debunked.
SR-71 has the same diamond shaped pulses (or donuts on a rope contrail) in its exhaust.
Since most of this is TS-SAP, debunking any of it is problematic.
That was my very first thought
“Reminds me of a Jerry Pournelle/Niven book named Footfall.
Great stuff.
“So another invention the military lets Americas enemies know they should also focus on.”
I guess no one in our military has the foresight that you do. :)
Another implication of this technology would be a single-stage-to-orbit aircraft that takes off & lands from a conventional airstrip. This is a jet engine that has the thrust of a scramjet, but also carries it’s own oxidizer.
“Not a comment directed to the OP..”
The names are similar?
Must be some long lost kin.
Of course, all of that can be explained in less provocative terms than as a deception operation or a secret hypersonic aircraft that is no longer in use because, with the Cold War over, its expense could not be justified. A few decades from now, a new tranche of documents may get dumped in the National Archives that tells the story.
Most of the supposed breakthroughs in technology that I have seen touted proved to be of limited effect, with many of them even being duds. The exceptions are the internet, the new genetic technologies, and the Green Revolution that averted dire predictions of worldwide famine.
With the price of fuel now, theyll save $382.
While the cost of fuel is a major consideration... with stretched out supply lines it becomes logistics and more logistics...
Using less fuel can be a very good thing.
“And of course they are hoping that gas will stay cheap for the next 8(?) years or whatever.”
A few years ago Com Ed put up a ring of gas peaker plants around Chicago.
I hope they last more than “8(?) years or whatever”.
Note the string of diamonds shockwave in the exhaust.
Can you give a clue of what that indicates?
Guessing it has to do with wave propagation/timing?
Like the CVCC? https://en.wikipedia.org/wiki/CVCC
Or some swamp gas powered engines that use a constant spark timed by port length?
That’s the way my non-electronic diesel works on my little tractor. With gas engines though, they will die when the spark is cut off. Whether supplies by a battery, generator, alternator or magneto, they need electricity to run. A mechanical diesel does not. I have to pull a little lever that cuts off fuel to stop the engine.
It’s indicative of a pulsed hypersonic shockwave. The rumored Aurora spy plane (or whatever it was) left a very similar contrail that’s been photographed several times. Aviation experts theorized it was the exhaust of a hypersonic scramjet powered aircraft capable of speeds in excess of Mach 5.
You couldn’t see the aircraft, but you could see the “footprints” it left in the sky.
There was one north sea oil worker who described an unusual looking triangular aircraft hanging on the refueling boom as it passed overhead. Sketches but no photographs.
Is this your response to anyone who posts anything critical of a government practice, as if they were infallible? If not, then instead of criticism for so doing, you should form a defense for the frequent disclosure of new weapons.
