Stupid 32nd ship designs ! I HATE DICKSCURVY!
"Forgot to change this one"
Background music from space engineers, my favorite spaceship buidling game 😀
The part about having to withstand weapons does remind me, I remember hearing that modern torpedoes work completely different from WW2 torpedoes, where they were trying to impact and explode. Instead, most torpedoes nowadays are trying to create giant cavitation bubbles under the keel, and snap the keel of the ship as the ship falls and water rushes back in
3:40 is that space engineers music 😱
just hoping I live long enough to see at least one of these methods used.
The subject of weapons fire breaking a ship's structure apart has me thinking about real-world torpedos. Many self-guided torpedos are designed specifically to aim to detonate under a ship's keel and effectively break its back rather than simply breach the hull.
Could be an interesting avenue of attack to think about for a sci-fi setting, weapon systems specifically designed to target the most vital parts of a ship's skeleton.
To be fair though, given the amount of power we are talking about it's not like you would need to rely on passive tension or support. for large structures, you could use active support, which would reduce the mass required as the heaviest part of active support is the ability to generate energy to run it, and this is a real thing, you can either shoot particles, ball bearings, liquid, etc, just some kind of mass at a target which can provide extra compressive strength to a structure or all the compressive strength, and you can do it in such a way where you regenerate most all of the energy and all of the mass used.
Even if you completely relied on active support for compressive strength, though you would rely on tensile strength a little bit, still, in the case of a spaceship.
John Ringo's Live Free or Die/Troy Rising series had an interesting idea: They would drill nickel-iron asteroids, fill them with volatiles (water ice), carefully superheat with solar lasers, and then the asteriod would "inflate" like a balloon. Drag it to deep space cool, and then you could cut/mold/fit the interior as needed with prefab sections to turn it into…well, you have to read the books! They were able to make them…considerably large.
Really innovative & varied use of clips for this one, Spacedock! Thanks!
But…not a spaceship made OUT of skeletons, right? We aren't that anime, are we?
There's a small wharf on the belt why not just order one?
You missed using pre-existing solar mass like asteroids and even small planets. Sometimes it's easier to just mine out something and use what you mine to refine as shielding.
Something I've learned to take into consideration in regards to interior design: people need a LOT more bathrooms than we typically consider.
" Hey Bevis, he said stiff " hu, hu, hu !
I had an awesome dream a few years back. I was in a large space suit (reminiscent of Warhammer) in a queue to fill up my air. The whole ship was like scaffolding with steel plates all over it. It had two large forks (200m ish) so I presume cargo went between those, perhaps in containers. Workers lived in their suit – there was no inside or outside of the ship. I was filling up my air, others were getting and chatting, another shift was asleep on the wall (magnetic feet and no gravity).
At the back were two huge glowing engines giving very little thrust – maybe 5cms-2 ish.
The whole thing felt very real and very practical.
how about this: a giant casting mold for the entire piece. Would be funny ig
Shoutout to battlezone ost
The barges I've been making at work make more sense now. Thanks!
Line go up good, water in ship bad! Got it!
I liked this channel more when it stuck to fantasy.
And the combined thrust vector must pass through the Center of Gravity of the ship. I don't get how this works in the Star Trek universe.
Do a deep dive into relativity space. Their 3d printing rocket parts and they discuss the designs unlocked by 3d printing metal
"Which would be heavier, requiring more fuel…to get between stars…" The pile on there killed me lol. Love the videos.
I think this is the third thumbnail change you made on this video, what's the deal?)
The Valley Forge cargo spaceship from the movie Silent Running is prominently pictured here. However, the location and nature of the engines for it are never explained. A single descriptive paragraph in the original screenplay refers to a Sperry corporation "harmonic drive." I actually met Douglas Trumbull several times and to this day I kick myself for not asking him about it.
I‘m sorry, but as someone who works in aircraft maintenance, I have to inject here. Monocoque aircraft still have frames (not formers) and stringers, but the skin is directly bolted onto them. In a semi-monocoque constellation, the skin is connected to the frames and stringers via special clips, wich allows the hull to expand and contract due to hull pressure. Monocoque hulls do not allow expansion and thus are unsuitable for pressure cabins and their multiple pressurisation cycles. Over time, material fatigue would set in and destabilise the hull.
Now I don’t work in rocket manufacturing, but from what I can see in the videos and pictures you show, rocket tanks seem to be built in a monocoque fashion with the skin directly attached to the structure, because a) the clips that would be needed to make it semi-monocoque would add a lot if weight and b) rocket tanks typically only go through a few pressurisation cycles in their lifetime. I don’t know how SpaceX do it with their reusable falcon 9, but even the most flown booster only has 28 cycles behind it. For comparison, most commercial airplanes go through at least two, if not more pressurisation cycles in a single day.
Tl;dr: Monocoque: skin directly attached to the structure, not suitable for repeated pressure cycling
Semi-monocoque: skin indirectly attached to the structure, adapted for repeated pressure cycles
This is the first time that I might actually want to use a video's sponsor
The mention of modern Trek was such a chef's kiss. I love the idea.
That makes sense.
4:31 Falcon 9 are less reliant on machined Iso/ortho grid and use welded stringers. 7:18 Many of those ships used as targets survived for some time.
The ships in my science fiction stories used inner and outer ceramic hulls that were 3D printed and fired in very large kilns. The inner hull provided most of the structural strength and was surrounded by an orthogrid structure where the frames and stringers are printed into the hull. These grid parts have a T shaped cross section so that the outer hull panels can be bolted to the isogrid.
The outer hull's purpose is protect the inner hull from impact from small asteroids and other space debris. It consists of separate panels that can be bolted to the inner hull's isogrid with some sort of shock absorbing material between the two hulls.
The main thrusters were mounted on wing like pylons to the sides of the hull while maneuvering thrusters were mounted to beefed up sections of the isogrid.
The ships used in my story were fairly small ranging from 5 meters long for small runabouts to 100 meters long for freighters and military vessels. The in-story rationalization was that there were problems "firing" larger structures where some parts of the hull would not be fully cured once the structure exceeds 100 meters in length.
I'm sorry, mono ₩H@T?
This channels inspires me to make some 3D models, because I love everything space related. Ive come accros this exact doubt. I was modeling a spaceship with ribs and panels, but It looked way older tech. Then I googled some F-35 manufacturing processes and saw that they are built like ships, with pre-made segmented hulls, and some smaller panels fixated later.
