Cool concept, but the rotating section won't work. It needs TWO contra-rotating sections to keep the craft stable, and this would be an engineering nightmare, but it is achievable.
@fragomatik15 күн бұрын
Look closer! The rotating habitat is counter-balanced by a dynamic flywheel (see time-stamp 00:16). To "balance" the rotational torque you need a counter-rotating mass of equal mass rotating at the same rate, or a SMALLER mass rotating at a FASTER rate.

I feel like the highly enclosed nature might make this a depressing habitat to live on given we evolved under an open sky and nature. I still favor the O'Neills design where radiation shielding can easily be done magnetically or via material construction/water layer... without making it feel completely boxed in, given the O'Neills are much larger and would have potentially enough space to emulate a blue sky.

What would the interior of the rotating torus look like?
@fragomatik6 ай бұрын
It would look like being inside a 1.5m - 2m diameter curved tube. The sides would be lined with storage spaces, exercise machines, and sleeping bags. The space is fairly cramped (barely enough space to crouch inside) but easily navigable as it's only a fraction of G (1/4 to 1/3 "normal" gravity). Note that the torus is for sleeping and exercising within. It is not a habitat for living within on a full-time basis. It is used to ameliorate the negative health effects of microgravity, supplemented by additional exercise. The effectiveness of such a system for countering microgravity health issues is currently unknown. It may be that only a fraction of G is sufficient, but exactly how much artificial gravity is helpful (and for how long one must be exposed to it for any benefit), is currently a matter of speculation. Obviously more empirical research and study is required to determine this, but it certainly would be worth the effort to find out!

@@lancewilliams4190 A fully "liveable" habitat would be too massive for the vehicle configuration shown in the video. The additional mass required would reduce the overall payload allowance and mission range, as it would require more energy to operate and more fuel/propellant/consumables to last the mission - it all adds up. I guess what I'm saying is that one can do anything if one can afford it, but space agencies generally want to be as cost-effective as possible while meeting mission objectives.

No need to imagine it, Scott, as the main idea behind this multi-mission design is that it is modular, in order to accommodate available tech. That is: different modules for different missions, using technology as it becomes available. The original presentation shows one configuration with chemical propulsion, and another with VASIMR. I chose to illustrate the VASIMR version. Of course VASIMR is really best powered by a nuclear reactor, but it *will* work with PVAs apparently <shrug> So the bottom line is that if you have a bi-modal nuclear-thermal propulsion unit (or even an advanced plasma drive like VASIMR) ready to go (for example), just bolt it on and away you go...

Nice work.I think such habitats would be much too vulnerable to damage from within and without.
@fragomatik10 ай бұрын
Thanks! I kinda get what you mean, but "vulnerable" is a somewhat relative term. For example: the ISS which is in essence a collection of disparate modules wrapped in thin aluminium sheeting has been in service for more than 20 years in Earth orbit. During that time there have been no serious injuries or fatalities. There have been some minor impact events from sand-grain-sized dust particles, and a coolant leak which turned out to likely be a sensor error. None of those events resulted in any significant danger to the station or crew. Surely the ISS would be *more* vulnerable than a massive habitat such as a Stanford Torus, and the ISS seems to have avoided destruction so far. The biggest danger to any large structure in space is from impacts, which are statistically *extremely* rare. Size Mass Rate of Occurrence ------------------------------------------------------------------------------------ 1/4" pebble 0.01 oz. Every 3 yrs 2" rock 3.5 oz. Every 7,000 yrs Boulder 1 Ton Every 250M yrs (Source: T.A. Heppenheimer "Colonies In Space") As for vulnerabilities from *within* - I'm not sure what you're getting at. Do you mean something malicious such as sabotage, or something accidental such as hardware failure? I suppose one could argue that it's possible to plan for such things in order to avoid any major or disastrous issues. The fact is that activities in space are inherently hazardous. However, the risk/reward ratio is high in favour of taking the chance since the rewards can be so valuable in the long term. Humans have always taken calculated risks in order to earn a "profit" - either monetarily, or in expertise and knowledge. I don't really see that changing in the future.

¡Welcome back, Fragomatik! I have a question, does the ship contain capsules or some method to "sleep" the crew members for several months, just like the 2001 movie? This would be very useful to prevent the crew from suffering from some type of mental problem for all the months they must be locked in a small capsule. In addition, less would be spent on food, water and other life-sustaining elements. It would also be necessary for the capsules to be placed in the centrifuge so that the bodies do not suffer from any problems due to zero gravity. Also, why did you stop uploading videos for so long?
@fragomatik10 ай бұрын
Hey thank you! There's no 'hibernation' facility necessary for this one. Although this is really just a fanciful design I cobbled together to get back into practice, it is based largely on the Discovery II (you've probably seen it here on my channel), which could do the Jupiter trip in about 3 months - so not too long. This ship is much larger, with a crew of 10+ and plenty of living space. It also assumes a much more efficient fusion engine, powerful enough to move all this stuff around. The centrifuge on this is huge by comparison to the Discovery II, and can provide a comfortable 0.38G (about the same as Mars gravity), and is intended for the crew to actually live and work in there. There's also a large Lab and Workspace module which is in zero G for research and other activities. I've included heaps of consumables storage (the 3 containers at the front between the shield and the centrifuge), so plenty of power, air, food & water to go around, especially if you factor in hydroponics, water recycling, and air scrubbers. In comparison some ISS crew have spent many months continuous duty in space (in a much smaller space and in microgravity!) and they have managed to stay relatively sane lol! Why was I away? Thanks for asking! Mainly it was due to computer issues. My GPU failed first, and a couple of months later the motherboard failed and took out a hard drive, too. I had to rebuild my system from backups and it took some time as other priorities took precedence - life can get quite complicated as you can appreciate! Due to the pandemic and other work related issues I was unable to do much about it until recently. Also, I've been a bit disappointed with youtube and the way they treat us small creators - it was demoralising and killed my inspiration. I'm not the only one affected - and I shouldn't say too much here in public - but suffice to say youtube run the site *their* way and there's not much a little fish like me can do about it. Never mind...it is what it is! Anyway, hope you continue to enjoy my modest little channel such as it is - and thanks so much for your support! 🚀

@@carlangastangas5698 Well in my imagination it takes around the same time to get to Jupiter (2 or 3 months) but since this is supposed to be a more powerful, efficient engine it can transport much more payload - so this means it can have a bigger crew and more equipment and supplies.

So they weren't apollo capsules on the lander noses afterall! They still look like they can separate though so the crew of 6-12 of the ship (estimate assuming the capsules have a maximum capacity of 6) can bail out when passing earth and get home if there's a failure on the ship. In terms of realism, not sure exactly what the shield is supposed to help with as I have it in my head it won’t be getting up to speeds wherein it can be severely damaged by dust grains. The only other thing is the propulsion setup. All it really needs to be is a few times its current length for thermal control and radiation reasons. A lotta nasty neutron reflection looks like its gonna happen and the power conversion radiators are gonna get quite activated. That being said, if made longer, it would struggle a little to fit on screen hence why aesthetics had to be considered. Good job regardless and I'm glad you're back

@fragomatik11 ай бұрын
Jettisoning tanks is done to save fuel. Why waste fuel transporting an empty tank? The empty tanks aren't really "lost" when they're jettisoned. Since their speed, location, and course at the time of jettisoning is known, they can be tracked pretty much forever. Tracking such things as depleted tanks and other "junk" is a good idea because it allows you to avoid colliding with it in future, or to pick it up again at some later stage. Classic Sci-Fi literature often has "rock-jock" characters that make a living by collecting discarded hardware, and salvaging it for re-use. If it's really old stuff, it may even have increased value as a museum piece.

Beautiful, except the engineering. Let me explain. If you had two rotating sections and were counter to each other, that would be stable, if complicated. Complicated because there are rotating parts, and non rotating parts of the ship. Seals, gears and energy are never going to be perfect, will wear and fail eventually. For example, the rotating shaft on a ship always leaks. Always. So, why not rotate the entire ship? Sure, it doesn't look as cool as what you have, but over complexity in space can get you killed. Best solution is simple, reliable using the least energy.

Although what you said is technically correct, it's also terribly obvious, and not exactly unexpected. But it is a bit churlish to denigrate the engineering as "not beautiful".

Examples of other methods (including rotating the vehicle around a short or long axis) can be found amongst my other videos on this channel.
