Where should the crew compartment go?

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

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 33 points 1 week ago

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

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

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

[-] Mirshe@lemmy.world 4 points 1 week ago

Oh cool, we reinvented the Me-163 Komet.

or between two, stacked engines!

This is NOT a real engineering blueprint

That right there is comedy gold.

[-] purplemonkeymad@programming.dev 20 points 1 week ago

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.

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

[-] VitoRobles@lemmy.today 3 points 1 week ago* (last edited 1 week ago)

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

[-] fizzle@quokk.au 53 points 1 week ago

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.

[-] Tar_alcaran@sh.itjust.works 41 points 1 week ago

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 9 points 1 week ago

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 18 points 1 week ago

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

[-] lemmyng@piefed.ca 14 points 1 week ago

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 9 points 1 week ago

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

[-] Ash@piefed.social 32 points 1 week 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.

[-] DivineDev@piefed.social 31 points 1 week ago

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 22 points 1 week ago

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 4 points 1 week 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 16 points 1 week ago

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

[-] Scubus@sh.itjust.works 2 points 1 week ago

Well it helps when aerodynamic drag pulls you upwards. I thought it was a drag force, but I guess it's a bit of a misnomer.

[-] Quexotic@sh.itjust.works 23 points 1 week ago

Gravity go up, gravity go down!

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

[-] SirActionSack@aussie.zone 4 points 1 week ago
[-] Birch@sh.itjust.works 4 points 1 week ago

With actual raptor!

[-] zarkanian@sh.itjust.works 3 points 1 week ago

Yo, dawg, we put raptor engines in your raptor engine.

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 9 points 1 week ago

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

[-] thedeadwalking4242@lemmy.world 19 points 1 week ago

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

[-] nuko147@lemmy.world 6 points 1 week ago

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

[-] SirActionSack@aussie.zone 5 points 1 week ago

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

[-] Deceptichum@quokk.au 17 points 1 week ago

The crew is stored in the engine:

[-] obelisk_complex@piefed.ca 17 points 1 week ago

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

[-] rImITywR@lemmy.world 12 points 1 week ago

And the crew. And the healizaie.

[-] Mnemnosyne@sh.itjust.works 14 points 1 week ago

I like he crew quarters being in the path of the methane flow. Makes thing efficient to route the methane through the crew quarters.

[-] ChairmanMeow@programming.dev 7 points 1 week ago

What about the raptor engine that's recursively nested inside a larger raptor engine?

[-] spechter@feddit.org 5 points 1 week ago

It's coupled by healizize

[-] Ummdustry@sh.itjust.works 11 points 1 week ago

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

[-] one_old_coder@piefed.social 10 points 1 week ago

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

[-] peoplebeproblems@midwest.social 9 points 1 week ago

It is non-deterministic.

This is my biggest gripe with GenAI.

[-] Kirp123@lemmy.world 9 points 1 week ago* (last edited 1 week ago)

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

[-] Alcoholicorn@mander.xyz 12 points 1 week 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 3 points 1 week ago

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

[-] Tar_alcaran@sh.itjust.works 6 points 1 week ago

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)

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 1 week ago* (last edited 1 week 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).

Expansion ratio with a 30ft nozzle gotta be insane
