Neutron | Stage 2 Cryogenic Test
HTML-код
- Опубликовано: 30 сен 2024
- In October 2023 we completed cryogenic testing for a Neutron 2nd stage. This crucial test involved filling the tank with liquid nitrogen & pressurizing it to expected flight pressures, then pushing it all the way to failure to test extreme tolerances.
As part of structural testing we push our tanks to Maximum Expected Operating Pressure (MEOP)...and far beyond.
Stage 2 looks bigger than I expected. Let's go Neutron!!
Its not.. those white structures arent house.. they r just small tanks, so it just gives the illusion its big.. look at the traffic cones nearby
it still looks big... lol @@merxellus1456
Rapid Scheduled Disassembly
Very important use.
I mean, rapid semi-scheduled disassembly
@@richardmillhousenixonnope, it was scheduled. They test as far as it would go, and obviously, it can't hold anything, so it was expected to fail
@@xNeuker They expected it to fail, but they don't know exactly at what pressure it will fail. That's what makes it semi-scheduled.
@@xNeuker They mean semi-scheduled as in they intend for it to explode, but they don't know the exact moment at which it will, since they're testing it to failure; essentially, pressurizing it more and more until it bursts. They can get a good idea of roughly when it will burst by running simulations, but won't know the exact time until they try it in real life.
That was a perfect failure. It looks like the tank exploded really evenly, which would indicate that there are no obvious weak spots and that they have got the manufacturing process down. Really exciting!!🎉
I'm really excited to see the progress of the Neutron. Let's go Rocket Lab!!! Greetings from ARG!!
Can't wait to see similar to these updates coming directly from Arg!! So many Start ups coming in hot!
3 argentineans rooting for Rocket Labs who would have thought!😅
Awesome ! Thank you for giving this videos, it's awesome to be able to see the evolution :D
I can't wait to see what is next, keep it up !
Great to see things are coming along!
Looking great! I am glad the testing seems to be going well!
Thanks for showing us the fun! I look forward to Neutron very much.
This is the 2nd stage tank!
Neutron is going to be much bigger than I imagined.
😀👍🏼

Would love to know how far "Far Beyond" is.
Go Rocket Lab! Go Neutron!
Can't wait to see an engine test!
Great job guys. We're waiting to see the whole beast soon
Ah, that'll polish out :D Great to see the progress!
Triple checked my audio setup before realizing that there is no sound at all ... Looking forward to further tests
Looks like Rocket Lab is using the same development processes as SpaceX. Build it. Test it in several different ways. Then prior to disposal, just see how far it can go before breaking! This allows determination of failure modes, and can also tell where some part is too strong (aka too heavy) and can be pared back. Go for it Rocket Lab!
I mean sort of, but this type of test is absolutely standard across all of the industry and beyond. Pretty much all pressure vessels are tested to failure.
The space industry is Not defined by Elon Musk. Sound engineering practices are vital in manufactured products.
@@gccchc2449 Where did this comment mention Elon Musk? This comment is talking about how Rocket Lab uses similar methods of rocket development compared to SpaceX, probably because the use of rapid iteration on larger scale is something SpaceX uses commonly compared to other space manufacturers. (Which is a method most people still struggle to understand)
I'm having flashbacks of Mythbusters.
Number 8 wire at its best!
To watch live, that would make a fantastic finale for a school science project/competition......
Be Kind
😀👍🏼
ITS WORKING
Oooh nice
Good test 👍
Great to see the progress you have made so far, and I am super excited to see what's next! Congratulations on a successful test!
And how did it do? What is the flight pressure? Theoretical maximin pressure? And actual maximin pressure?
Awsome, congrats to the team!
There was an earth shattering kaboom that'll make some people very happy
What are the results? What was expected and what did it withstand?
Are we talking 101%,150%,.. operating pressure?
Ok, so exploding was expected behavior. Got it lol
Knowing just how far it can be pushed, and from that how large the safety margin is, is data that is worth the cost of destructive testing.
I like the idea of filling a giant metal container with clouds and then letting it explode
Awesome...let's gooo!!!
Was supposed to launch this year. How close are we now?
you guys are gonna run out of names soon. what will you do after the proton?
No sheepies or moo moo's were snap frozen in this 🤣⛳
Nothing better than learning from explosions!
Structural tests like these are required by everyone, so it is nothing like SpaceX, instead, it appeared to pass the first time which highlights first-time quality engineering. Well done Rocket Lab for great engineering :)
Please name the first flight "Jimmy"
That looks pretty cool
"...and far beyond" awesome!
Bob Stop... Bob press stop, BOB!!
Lfg!!!
So far ahead of Blue 0,0.
Did it pass?
It's supposed to blow up, dude
True but did it go past it's target pressure first?
@@mboggs8850I am assuming yes. They brought it up to operating pressure for the test and then surpassed it to failure.
Yes, it's a failure test. They test it until it fails. This was reported a couple weeks ago on X
EPIC! 💯🔥
I wonder how thin that wall is
Oooh. Aaahhhh!
WEN MOON
?
If i might ask....what was the bursting pressure? But seriously it looked so cool.....yes pun intended....
I mean at least it's a fun test to watch :-)
Ehh
TTF... pretty simple guys. Unless ya know ya can't go. Do the math. 1br here, =x to the 10 -br up there. You gota absolutely overpressure these things huge to failure so they hold "out there". Then do more math for weight/mass/Dv, etc. Its rocket sciene. RL has this. Keep it up Davy Boy and Team. ❤🎉😊
Really leaning into that SpaceX style rapid development huh.
I'm all for it

👍🏻
WOAH! Nice test to falure! It was a succesful failure! Lots of important data learned :)
Awesome. Can’t wait to see this one fly. That will be some cold as heck grass right there.
so are you all set w the 1st stage? are you "bending metal" yet on it?
Thanks for showing us the test. Good luck.
Was is supposed to go boom?
Yes
Faster than blue origin, impressive!
I love Rocket Lab. Peter Beck is a great dude.
Please take note from SpaceX and share a ton of videos!
how far beyond did you push it?
Nice to see some testing reminiscent of the starship test campaigns. Nothing will have as much visibility as that with all of the 24/7 livestreams, but excited to see a peek at Neutron hardware!
You say SpaceX you are meaning Musk obviously. Musk also didn't invent the fail fast or 'agile' method. The idea was picked up by and elevated by Silicon Valley. You can also see the same approach in regenerative permaculture where the likes of Jean Martin Fortier uses and teaches old and Silicon Valley methods to make viable profit making small food production market gardens at a far higher rate of food per square metre than a industrial monoculture farm. SpaceX is cool, Tesla is Cool Musk is meh.
So freakin cool.
Go Rocket Lab !
why was the tank covered in ice in the close up picture but had very little ice on it when it blew up?
Maybe they used a non cryogenic to fill it? Not sure.
It'll buff out
Hell yeah
:)
All that poor liquid nitrogen😥 So many school chemistry and physics demonstrations have to be cancelled!!😱🤬
wen hop?
How many bar of pressure when it ruptured?
And since the carbon fiber submarine imploded just a few month ago: How many pressure and temperature cycles is the carbon fiber laminate expected to last?
Carbon fibers strength is in its tensile strength to weight.
So a pressure tank is using carbon fiber for its strengths, a submarine is not.
Those two things cant really be compared in order to build any conclusions about how the other will perform.
Internal pressure vs external pressure are two very different things when it comes to carbon fiber.
Only needs to hold a few bar (less than 10). Titan was closer to 400 (inwards).
@@Vatsyayana87 I know that. But carbon fiber laminates are sensitive to temperature changes - and liquid cryogenics in the cracks suddenly becoming gaseous can do a lot of damage.
Thats is true, though these guys are real pros, im confident they will do the proper procedures like ultrasound or whatever they use on every inch to ensure there isnt the smallest bubbles in the weaves.@@asmael666
Was this intentional? I only ask because there was still scaffolding around the tank, which I feel would have been removed if it was intentional.
Read the video description
Yes. After filling to flight levels, they pushed it to failure. It's in the description if you want the exact wording they used.
It was intentional. Not only do they want to know it will stand maximum operating pressure but they also want to know point of failure. This gives them a good view of the overall integrity of the tank.
I just remember seeing some speculation when this video was first released in October that it wasn't because the scaffolding was still there
