The sabre engine works, and it's going to change everything.

Good to hear things are progressing

Modern bbc in a nutshell:
>a 420C stream of gases
>the energy in a 1,000-degree airflow
Number [degree] [UNIT] for temperatures
>1.5 Megawatts of heat energy - the equivalent of 1,000 homes' worth of heat energy.
Per day? Per year? Please specify.

Anyway, I'd love to the amount of liquid helium needed in that test, or the amount of energy needed to cool the helium.
That would be quite important for an eventual rocket, but for some reason, the article doesn't mention it anywhere.

Per day I'd guess.

inb4 someone calls you a shill:
>The sabre engine works
Who do you arrive at such a statement from
"They did a test of a crucial component"?

"My car that I haven't built yet works, because the air filter works." makes as much sense.

Fucking brainlet tier. Besides, they tested one component, 2 mach short of its design range and they call it a success? Lmfao

*at temperatures
They didn't test anything at Mach anything yet.

Only for the US though. Britain can't afford to implement it, the Eurozone wants their own in-house version that will take decades to develop, while Russia and China don't have the competence to pull off such an engine even if they pirate the design documents.

Air filters are important if the engine runs off compressed air. Ground tests in a simulated wind tunnel are comparable to testing a stripped engine, transmission and wheels on a dynamo.
