As someone who drafts for a living, these drawings are shit and provide absolutely no useful information. This looks like a drawing from a project manager they did on the back if a napkin at lunch which they'd then bring to me and ask me to make actual useful drawing of.

[–] HeyThisIsntTheYMCA@lemmy.world 4 points 4 hours ago

yeah, these are the "give these to the MBAs to make investment bullshit out of" type drawings.

The crew is stored in the engine:

[–] thedeadwalking4242@lemmy.world 14 points 8 hours ago (2 children)

The crew is gunna get a little hot sitting that close to the raptor engine I think.

[–] nuko147@lemmy.world 3 points 5 hours ago (1 children)

What do you mean? This engine burns crew according to AI.

[–] SirActionSack@aussie.zone 1 points 5 hours ago

Catalysed by raptor. You can't just burn crew, think of the gravity.

[–] chuckleslord@lemmy.world 3 points 6 hours ago

That's obviously what the healizaie is for

[–] Quexotic@sh.itjust.works 7 points 8 hours ago (1 children)

Gravity go up, gravity go down!

Sometimes I worry about LLMs taking my job, sometimes I don't.

[–] Birch@sh.itjust.works 2 points 4 hours ago

With actual raptor!

[–] obelisk_complex@piefed.ca 12 points 10 hours ago (1 children)

Hey, at least it put the raptor inside the raptor engine this time!

[–] rImITywR@lemmy.world 10 points 9 hours ago

And the crew. And the healizaie.

[–] DivineDev@piefed.social 20 points 11 hours ago (2 children)

God I'm such an idiot, I always thought gravity pulled rockets downwards and you need to apply thrust to take off, but it's the other way around! You run the engines to stay on the ground and board the rocket, then just switch them off to start!

And the recursive raptor engine that contains itself three times, genius!

[–] dmention7@midwest.social 17 points 10 hours ago (1 children)

I think the really visionary point is that the crew goes inside the engine.

All these fucking nerd engineers have been putting the crew outside the engine for decades, to the point that some even put the crew on the opposite end of the rocket!

[–] Axeman666@sh.itjust.works 3 points 6 hours ago

Well duh, how else do you keep the crew warm in space? It's not like you have heat pumps or furnaces.

[–] Varcour@lemmy.zip 12 points 11 hours ago (1 children)

Well, you see the gravity thing only works for the lower third of the rocket. Then gravity changes direction, that's why you need the engines to create thrust

[–] galoisghost@aussie.zone 52 points 16 hours ago (2 children)

This is NOT a real engineering blueprint

That right there is comedy gold.

[–] VitoRobles@lemmy.today 1 points 5 hours ago* (last edited 5 hours ago)

The comment in the image also looks like pure AI too tbh with all the emojis

[–] purplemonkeymad@programming.dev 17 points 14 hours ago (1 children)

I genuinely thought this was someone upset someone had said it was at first. Then the absolute gap in understanding that made that person think someone might actually mistake the picture for one.

[–] Windex007@lemmy.world 1 points 9 hours ago

The text is just the output of a "make an insightful LinkedIn post about the power of generative ai"

[–] threelonmusketeers@sh.itjust.works 61 points 16 hours ago (4 children)

Where should the crew compartment go?

On the engine, of course! Right above the HEALIZAIE and the FALT.

[–] slazer2au@lemmy.world 25 points 16 hours ago (1 children)

How does gravity effect this? Well, that's the good part. near the heat shield it pushes from front to back, but near the thrusters is pushes back to front cancelling it out.

[–] Tar_alcaran@sh.itjust.works 24 points 15 hours ago

The gravity cancels out, letting aerodynamic drag lift the rocket into space.

[–] gnutrino@programming.dev 10 points 15 hours ago* (last edited 15 hours ago)

But don't forget to put the actual crew on the other side of the engine to the crew sections.

or between two, stacked engines!

[–] fartographer@lemmy.world 4 points 16 hours ago (1 children)

Where you're always one leak away from being horrifically oxidized or slurped through an engine.

[–] Mirshe@lemmy.world 0 points 10 hours ago (1 children)

Oh cool, we reinvented the Me-163 Komet.

[–] christopher@lemmy.ca 1 points 8 hours ago

Just looked up a pic of that plane. Looks like a toy

[–] fizzle@quokk.au 43 points 15 hours ago (2 children)

I kinda wonder what this person thinks people with jobs actually do all day.

Just kinda goof around, make doodles in your sketch book, you know... engineer stuff.

[–] lemmyng@piefed.ca 10 points 11 hours ago (1 children)

Oh shit, at first I thought the person in the screenshot was mocking the AI's product, but they actually believe it's a good result?!

[–] fizzle@quokk.au 7 points 11 hours ago

Yeah. Their their grift is teaching people how to write prompts apparently.

[–] Tar_alcaran@sh.itjust.works 34 points 15 hours ago (1 children)

Legit yes. AI boosters really think that.

They think programmers just type stuff. They think engineers just draw stuff. Mechanics just turn wrenches till stuff works again.

It's because these people don't know shit about fuck. That's why they think everyone's job can be done by AI. After all, AI can doodle and type and turn wrenches. Unlike their job, which is complex and nuanced.

[–] fizzle@quokk.au 6 points 14 hours ago (1 children)

Unlike their job, which is complex and nuanced.

I don't think the person who wrote this does anything technical for a living. I think their job is some BS training shit show "we will teach you how to write prompts for LLMs" or something.

[–] Tar_alcaran@sh.itjust.works 12 points 14 hours ago

Oh, I agree. But THEY think their job is complex and nuanced.

[–] Ash@piefed.social 21 points 15 hours ago

Aerodynamic drag helps accelerate the rocket up. Got it. And the rocket takes its own oxygen with it, and sucks methane from the air and space. I didnt realise gravity changes direction from top to bottom, then goes sideways (obviously the methane alters gravity). And great idea having the crew compartment in the combustion chamber... must stop the crew from getting cold.

[–] peoplebeproblems@midwest.social 8 points 12 hours ago

It is non-deterministic.

This is my biggest gripe with GenAI.

[–] lefty7283@lemmy.world 2 points 9 hours ago

Expansion ratio with a 30ft nozzle gotta be insane

[–] Ummdustry@sh.itjust.works 6 points 13 hours ago

If only there were some kind automated tool to turn 3d models into orthographic & isometric drawings...

[–] one_old_coder@piefed.social 9 points 16 hours ago

Name and shame so that we can make fun of him.

[–] Kirp123@lemmy.world 8 points 16 hours ago* (last edited 16 hours ago) (2 children)

Damn, didn't realize rockets ran on methane. Just like my stove.

[–] Alcoholicorn@mander.xyz 12 points 16 hours ago

Yes a lot of modern engines run on methane. It doesn't have to be as cold as H2 and its much more volume-dense.

Combustion is much less complicated than with kerosene and other big hydrocarbons.

[–] mkwt@lemmy.world 2 points 16 hours ago (1 children)

Saturn V first stage ran RP-1, a kerosene fuel like Jet-A or JP8.

[–] Tar_alcaran@sh.itjust.works 6 points 15 hours ago (1 children)

Yep, they went to the moon on fuel that could also run a truck (if you don't particularly care about still running it next week)

[–] threelonmusketeers@sh.itjust.works 3 points 15 hours ago (1 children)

if you don't particularly care about still running it next week

Wouldn't RP-1 burn cleaner than run-of-the-mill diesel?

[–] Tar_alcaran@sh.itjust.works 4 points 14 hours ago* (last edited 14 hours ago)

Sure, the burning part isn't the problem.

Diesel has small amounts of lubricants, and those are very much needed for all the tiny little moving parts in fuel injectors and probably even in the engine itself. RP-1 doesn't have those.

Also, I know jet fuel will absolutely destroy just about every rubber not specifically designed for it, and that may apply to RP-1 as well.

Also, starting your rocket fuel car in winter is probably going to be a real chore, since the vaporization point is much higher, and modern cars don't come with preheaters that can handle that anymore (thanks to those fuel injectors).
