[Here’s an article](https://arstechnica.com/science/2017/07/japanese-company-preparing-for-countrys-first-private-rocket-launch/) that talks about the rocket engine test, and the Japanese company behind it.
What fuel is this using?
God damn, I forgot what it’s called but the diamonds in the exhaust are phenomenal
When you’re taking a test and look up and see 5 minutes left and you’ve only done 1 problem
Surprisingly, there is a subreddit for rocket engines being tested: /r/engineteststands
It’s working, it’s working!!!
ELI5 how this can be producing (what seems to be) incredible power while staying basically still. What is it attached to that is resisting the force of the propulsion?
What material is the “tail pipe” or whatever it’s called made from it looks like it’s about to melt as the video ends

On the Saturn V rockets used in the Apollo Program, the engines took the exhaust from the turbines that pumped the kerosine and liq. O₂ into the engines and funneled it around the outside of fuel/oxidizer mixture where it acted as an insulator, protecting the nozzles from overheating.
[Here is a video of exactly what I’m talking about.](https://youtu.be/DKtVpvzUF1Y?list=PLCEDD9CA9826CA71F&t=120) It resulted in that characteristic dark shroud around the rockets’m thrust cones.
And the earth spun a little faster that day.
Alright. I have a question for you science guys here. If i move fast enough through that flame, would it not hurt me? And if so, how fast would i have to be?
Me after eating Mexican.
I wonder how fast you’d die if you were behind that.
What is the rocket pointing away from? Where does all that go?
Hot wings for lunch…check
Taco bell for dinner….3…2…1….
IGNITION!

As an actual retired rocket scientist from NASA/the shuttle, they gave a slight problem with their power head and possibly the Ethanol injector.
I wonder how fast your hand would get effed if you just ran it through!

Great thrust, average stroke.
Is there a significant loss in efficiency of the engine due to the unclean burn that happens towards the end of the GIF, presumably because of the tail pipe heating up? And if so, is there any practical way around it?
What is a nozzle like that made of? Some sort of inconel? Maybe graphite? That thing is cooking!
With rocket engines with such high levels of thrust( like this one). How can one calculate how to properly secure it during tests? Furthermore , how would you know if you secured it properly prior to knowing how thrust will be given off by the engine?

An engine test video without the roar is no engine test video at all But yeah, that’s still damn cool.

And not just like, oh hey thats a bit chilly… Hundreds of degrees below zero. They can form icicles… while at full thrust.

whoooshhhhhHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
How is this not upvoted to the front page. So f’ing cool.
I would like to throw things in there.
I just want to throw stuff in there and see what happens
Mach diamond porn.
Can I light my cigarette on that?
Watching that exit turn bright red reminds me of eating Taco Bell.
