Chill down about Archimedes! | Lets have an honest talk!

All I know is that they better make sure they anchor that engine down when they test fire it.😂

I think they are still running the Pre-Test Checks. I can imagine those would be quite complex - testing all that plumbing for a start. I've seen videos of a lot of hot fire failures recently - they don't want that!

Patience young grasshopper

I ask myself only one question, where is Peter today? Peter will be in the location that means the most to him - the most important thing of the moment. So, where is Peter, the chief engineer? At STENNIS, leading his people? will not leave till ARCHIMEDES fires? No. In New Zealand then, where prep is under way for non-American Launch and Space Systems? Maybe. Or Long beach, LA, US. Probably. If true, where he is right now, is where his heart and mind is.

The problem is management is not providing updates. There should be communication about any problems and what tests are being done and when. Also, it is frustrating that they took a loan out months ago for an acquisition, but nothing has happened. Do you think they had a specific company in mind at the time and it fell through or was the aim just to have cash on hand if a good situation arose?

Vince it's not the misunderstanding of the complexity of a rocket engine but more about RKLB setting their own timelines, which they aren't achieving.

So .....hot fire is 2 days late and you come out with a 14 minute video about it? 😂😂😂

I assume that they will do many tests during a hot fire to find the optimal performance. There will be I assume some options too for RKLB to investigate with different parts or settings. They may also be testing how many times an engine can be relit. Usually we only get to see the flamey end go brrr, during a rocket fire. It does look like it is a more involved process, than what a 15 second clip would suggest.

Let's put it this way. In case that they haven't turn the engine on yet, neither we nor they have any idea when it will happen. We are not rocket scientists and according to them the Archimedes hot fire test should have already taken place in 2022 🙂

mate... xD

When living near a hot fire test area, you can hear the blasting for miles. Has anyone reported hearing anything yet?

Elon Musk would have blown up three engines by now! Rocket Lab is clearly more measured in their approach, not a bad thing.

I’m not worried about the engine test campaign. It is in good hands. What I am worried about was in your last video your spreadsheet projected a very underwhelming $19.65 in 2030. Sad. Regards Pete.

RKLB's oxidizer-rich staged combustion cycle design has many engineering complexities that the Rutherford avoided. Balancing out all of these inter-connected factors can require a lot of trial and error. Also, engines establish a combustion stability at cerrtain flow rates. Since Peter's desire is to run this engine on the cold side, this can be problematic if it put the combustion cycle in a less stable state. Just a lot of stuff to work out, not to mention the material-side of really hot oxidants. Peter is brilliant and these issues are solvable, but complex problems are by their nature much more variable in their timelines to a solution.

Um.. yes, but it has been a month since RL put up their video showing Archimedes on the stand and saying that they had almost completely final tests. it would be nice if RL we a bit friendlier to those of us who love to get down in the weeds and explained precisely what has been happening the past few weeks. There's only a certain amount of things that can be inspected/tested with a cold/dry engine. Have hey run any fluids through it? Any cryo fluids? Any spin tests on the pumps, using inert gases? I'd have thought things like manufacturing defects, rotor balances, sensor outputs etc would have been verified before it ended up on the stand. This is why I expected a hot fire in a week or two. So, whats' the hold up? Is it the stand itself? Is it paperwork?

Thanks for the video. I didn't saw that they wrote that they were iterating on the engine. So with that info my thoughts is that they tested the engine but didn't reach the performance they wanted and are now 3D printing modified parts to modify the engine for a second round of test.

Everyone is frustrated with rocket lab communications. But with the exceptions of SpaceX, rocket lab is doing a better job than everyone else in the industry... give them a break. Every other company communication is like this.

1) we have a rocket program.
2) 2 years later here is a hot fire tested

The rocket engine testing probably has an reiteration process which, unlike SpaceX in which reiteration involves blowing things up, involves modifying and swapping out 3-D printed parts as data comes in from pretests leading up to attempting optimized hot fire testing.

I don't think Rocketlab benefits anything from publishing first hot fire, if they do short ten second burn first for example - sure it would temporarily boost the stock, but nothing that would last and provide true value to investors. I guess they could've been already doing the tests like you are suggesting based your ChatGPT research. Likely they'll probably do full flight duration tests multiple times if everything is working well. And after they've achieved certain number of full duration tests, they'll likely do destructive test, or at least push the operating limits to 20% above operational limit, so they know they how much room they have for errors. And after that they'll either stop or keep pushing it until it fails. After they have all test data and they can come out and say, that they've done complete test cycle and the engine is certified to flight in their books - and they can start mass producing - that's what's going to push the stock to 20-50% and likely stay there, since one of the hardest pars of the Neutron development has been completed fully. Then it's mostly about putting things together, static fire and first launch.

This is easily one of your worst videos. Please stop consulting AIs.

Thank you for your content. I was thinking all the time like „chill, if they do not fire today, they fire tomorrow.”

So thank you for your effort. We are just folks holding shares and being impatient.

Reply to​​ @paulcarter7445 . Well, no engine, no rocket, nothing leaves the surface of Earth. You have too small a rocket, ELECTRON, and after 50 launches over 7 years, the share price closes today at $4.97. No matter how well Space Systems are doing, the market brushes that a side. The fact is, the market says, no NEUTRON "at the pad" in 2024, as they "said they were going to do", and so today the company is only worth $4.97 a share, the market declares, no matter the excuses, or plans for the future.
