Maybe, even though they're easier to transport up to orbit you'd still need to haul the water to fill them up, but otherwise does a good job at protecting against cosmic radiation.

The advantage of an inflatable module is that it allows the module to be mass limited in size rather than volume limited.

Generally speaking habitation modules aren't heavy enough to fully make use of a given rocket's up-mass capability, but they can't be any bigger and still fit in the payload faring, so the capability is wasted. An inflatable can be built so that it uses up all the payload margin as structural mass, then in space expand to make use of that structural mass to become much larger than any launch vehicle faring.

There are exceptions to this and inflatables aren't good for some purposes but that's the main idea. Launching the station in your pic related would require a vehicle faring much larger than anything that exists today or will in the near future, if it launched inflated. When stowed it'd fit in the SLS faring.

There are already two unmanned inflatables on orbit, in addition to the small one docked to ISS. They need manned spaceflight in order to get people up to them, so they're only a meme until SpaceX and Boeing get their MSF going next year.

there's nothing special to it, its just the inflatable membrane, with structural struts, all the life support infrastructure, and technology gets installed by following missions.
the one they tested on the ISS was a prototype of an inflatable storage compartment. it was quite small deflated, you could pack like 10 of these things into the payload of a falcon9, and add with just one mission a shit-ton of cargo space to the station if that inflatable tech wouldn't be so sketchy

you dont want to have a meteorite punctured ultra high capacity battery in space.
when that shit burns, it burns, you cant put that fire out as long the thermal runaway in the cells is going on. and electricity is maybe the most important thing to keep your life support going, you want to tuck the batteries away

[Anonymous No.9098021]

>>9096140
ah cool, you a student?

as for analysing, i don't really know either. They haven't specified what they're looking for, but I would guess check the outer hull against the internal pressure, check the ties/struts against the centripetal force (because it has to have artificial gravity - dunno how else to do that), maybe something about the dock - dynamic loading from an "impact" of an arriving ship? dunno really.

How much progress have you made? the deadline is the 1st sep but I have a dissertation to do too so i haven't really done much yet.

Not a student.

Grad + 3

I've done no work - working on my IPD forms because I'm going for chartership too.

I agree, basic checks and a few indications of section sizes should suffice, but everyone is going to come up with inflatable + spinning ring IMO. I'm trying to come up with something unique or look into stuff that people wouldn't usually consider.

Good luck.

[Anonymous No.9098085]

>>9098056
i think you're right that everyone is going to come up with the same general idea. generating the artificial gravity is going to make the possibilities pretty limited imo.

i think the key deciding factor is going to be the details of how it's constructed, rather than the overall concept.

best of luck to you too.

First off, are you sure they would use an ultra high capacity battery rather one optimised for power/weight AND safety?

Secondly, a thermal runaway is avoided by maximising dissipating surface area so the use as an inner lining is ideal also for getting rid of heat. Also, a centrally located high density battery location as shown in the figure would maximise the chance of thermal runaway running to completion and total loss of integrity.

Clearly all indications are that they would never use a battery with the chance of thermal runaway from the very start of the design.
