Forgot to say.

For movement you use pretensioned springs. And build an exoskeletton for legs and build your chest protection on that. Ao that its selfsustai ing ita weigt and you only have put energy into move it. Like a shopping cart where its easier to puss a full cart then carrying all.

And for joints use kevlar or dyneema

>>31374762
The power source is still the biggest issue.

>>31374837
Not really. Pretensioned springs and wired to your legs. So you have to use minimal force to lift

>>31374854
and what about your arms?
and what about your spine?
and what about movement?
and what about your joints?
and what about your gear?
its called POWERED armor for a reason. Otherwise you're just some guy in a big, armored suit thats slower than a normal soldier, less mobile, with a much larger profile and shilhouette, and in no way benefits anyone otther than making them die of heat stroke and being unable to be moved or retreived in their 500 pound metal coffin.

>But really OP, the problem is and always will be power sources. The only way you're going to get close is putting a small engine powering a hydraulic pump.
Power source isn't that much of a problem actually. You need to use water cooled electric motors instead of hydraulics. Where it gets difficult is reduction gearing, to get decent efficiency out of the motors you need extreme gear ratios like 50:1 which will have to be custom made. The best li-ion packs would probably give you 12 hours or more.

The main point of power armor is less to do with the armor and more to do with the firepower it allows you to carry.
Power armor by itself is just an oversized, slow-moving target.

Lol no. Not even close, seeing as how darpa can only get 4 hours on their exo suits. Which don't carry any armour.

>>31375195
Ill create a perfect energy source when you adress the issues without it. If you fall over in something that heavy, bend over and blow out your spine, twist too fast and snap your torso around to face 180 degrees behind you due to weight and momentum than in all those cases you will die.

The point of powered armor in most every concept is as a mobile heavy weapons platform, not a giant knights suit of armor. And for that you need a small and light enough power source that can generate enough power to that suit without killin the pilot with radiation.
but the more power you need the bigger you need to make that power source, and the heavyer it makes the suit, and the heavyer you make the suit the more power you need to move it, and so on and so forth...

>>31374795

I've seen napalm like IEDs turn aluminum Bradleys into smoldering piles.

Aluminum is shit for armor.

>>31375328

>>31375326
>bend over and blow out your spine, twist too fast and snap your torso around to face 180 degrees behind you due to weight and momentum

Those sound more like incompetent engineering than anything inherently wrong with the concept.

>>31375390
So it needs physical or electrical governors to limit rom, add 10 pounds, need more power, add 2 pounds.

>>31374762
If it's powered armor, why use titanium rather than steel? Titanium has more volume than steel for the same amount of protection, meaning the suit is going to be a lot more bulky than it has to be. Weight is less of an issue because the suit's legs are going to be powered.

That been said. Wheels/ tracks are better than feet, a box has less surface area to armour, not many good hard point mounts on a human frame and you can only pack so much on your back.

A personal microtank will do what you want, keep you lower to the ground, hold more equipment, protect you better and can actually be built.

Honestly we should just be using IC engines. A Wankel is 1/3 weight and 1/3 size of a piston engine of same power. I don't know what the fuel economy for a Wankel power armor would be but I guess you'd need something that could run constantly for 3-7 days.

Power armor is never really going to have a legitimate usage.

any role you want power armored troops to fill can be fulfilled by lighter armored troops with vehicles, robots or drones.

I would take pic related and change it slightly.

The armor covering the legs and arms will be made out of kevlar,ballistic nylon, fiberglass and high strenght plastic to keep weight down and boost up protection to atleast lvl3A, maybe lvl3A+ since it would be great if it could stop armor piercing pistol bullets.

The armor covering the torso would be made out of ceramic with titanium backing boosted by a very thin layer of high hardness steel with kevlar padding as the final layer of defence and for absorbing any blunt trauma.

And then you have a powerd exoskeleton underneath the armor thus translating into powerd armor.

That would be an endoskeleton, Anon.

Dont forget disk breaks in each joint. Those muscles work better popping instead of slowly inflating. They are cheap, powerful but not precise. Computer assisted breaking can be.

Use a gas turboshaft, I'm a fan of routing the exhaust into a compressed air pneumatic system and hope critical counterdamping deals with the attendant issues of c.a. systems being 'springy'. The turboshaft is not only an electric power generator for all integrated systems, sensors, and displays, but it also obviates the need for a secondary compressor in pure ekectric models.

Repairs are as "simple" as detatching blown hoses and bad connectors for new plug and play units; a damaged controller is best situated in or just below the backback utility sections as another pnp system quickly routed through a primary bus.

The biggest downside is the noise of a turboshaft and fuel consumption, the upside is raw power loads let you turn a soldier into an armored one ton light assault vehicle that can clear rooms, also, the spinup sequence will give our troopers raging tech boners.

>>31376049
Yeah now you have a vehicled sized suit. Good job. Very useful.
Plus you need a shit ton of armor to keep all the engine parts in working condition, which would make the suit extremely heavy.

It can work on a three-quarter ton model with 1" steel equivalent anti-pers plating all over, most of that weight is actually armor plating; the exoskeketon, based on the hypothetical bom, only weighs about fifty pounds plus another hundred or so for reinforced joint bearings and eight-ton actuator groups on each limb subunit. With 900lbs of conventional steel rha as the baseline, you can jack up the cost per unit to bring down weight with advanced ceramics. Steel is just easier to cut for custom-fitted limb lengths.

All the problems with power armor disappear when you take the people out

by the time we can build reliable articulated powered suits of armor out of materials lightweight enough to be practical, we'd be better off just piloting the suits with AI and filling the meat-space with extra bullets.

I mean, how do you solve the issue of fitting every suit of power armor to each individual soldier? What happens if a soldier's power source fails and they find themselves unable to move? What do they do if they raid an Afghani compound and need to climb a shaky wooden ladder to get to the upper floor? How do they get in and out of cramped APCs?

In any case, the whole "walking tank" concept of power armor doesn't seem very practical to me. Load-bearing exoskeletons for infantry? Sure, that's worthy of pursuit. But I wouldn't armor that shit until something lighter and slimmer is possibly than that monstrosity you're suggesting.

Let's say your armor and the tank are the same weight, 500 lbs. The bottom of the tank is about 2'x3' so you Hebrew 6ft2 to put that weight onto. It comes out at <7 psi.
Now a human foot is only about four inches across by about a foot in length. Let's say your armor triples the width for stability. So it is on 2 square feet (lel) which is 20 psi. That will make a big difference when it comes to a structures integrity.

Armor worked for warriors because it helped them offensively in melee, not just take hits.

>>31374762
OK, I know some stuff about this particular subject but won't be able to go into much detail.

First of all, power source. Forget batteries, as they drain they become dead weight. Fuel cells work here, however we have to be picky with the fuel. Hydrogen work but gaseous hydrogen offers shitty energy density. Notice H's place on the periodic table? It's with alkali metals, lithium, sodium, potassium, etc. Hydrogen does indeed have metallic properties, but it has to be in solid form, which takes tremendous pressure, the like of which is found and the centers of planets like Saturn and Jupiter. It's been theorized that these planets actually have cores of metallic hydrogen and other solidified gasses, when the force of gravity overpowers the nuclear strong force that normally keeps atoms separated it forms various types of what is called degenerate matter. While scientists haven't been able to observe degenerate metallic hydrogen directly it's thought that the protons and electrons of metallic hydrogen form a crystal structure the same way two types of atoms form a crystal structure in salt compounds, think sodium and chlorine in table salt. Physics-wise, this means that the metallic crystal hydrogen occupies a lower energy state than gaseous hydrogen, meaning that once compressed into a crystalline metallic solid the hydrogen will probably stay compressed.

Cont.

>>31378554
So, remember what I said about energy density and how gaseous hydrogen sucks? Well with metallic hydrogen you've got an incredibly energy-dense material without any of the drawbacks of attempting to store hydrogen in a solid substrate like lithium hydride etc. Now all you'd need to do is liberate the hydrogen atoms from the crystal structure, which would be easy to do using a laser to vaporize a bit of the surface at a time. That hydrogen goes into the fuel cel and bingo-bongo, clean, portable energy.

Cont.

>>31376271
Why not just have the robots be remotely controlled by a pilot like modern drones except with more control to rule out the possibility of AI fuckups?

Imagine if you put an operator like Vining into the pilot seat and gave him multiple units to control.

>>31376271
By the time we can build reliable articulated powered suits of armor, AI will STILL be in its infancy.

Remote-control is an option, but there are latency issues to deal with.

>>31378597
OK, so solid Hydrogen, great. Hand jobs for everyone! But apparently it takes an entire freaking gas giant planett to make the stuff. Fuck. Well, yes and no. If you'll remember what we're currently trying to do with nuclear fusion, that involves using all manner of magnetic fields, lasers, etc. to squish certain types of hydrogen together hard enough that they fuse to form helium, releasing a ton of energy in the process. With that in mind, what we'd need to do is smash hydrogen together in the right way that instead of fusing to helium, the hydrogen settles into the nice crystal structure I've been talking about. We're working on that and that's about all I can tell you.

>>31375846
Maybe not powered "armor," but powered exoskeletons have a use in being versatile heavy-lifting tools.

Someone could then bolt armor onto that to make power armor.

>>31378659
Samefag here, also the future of armor is diamond-like carbon, specifically a form known as Lonsdaleite. In fact, anything and everything that needs to be strong and durable will be made out of it, I imagine. It's that good.

I normally just lurk because nofunz yet, but isn't one of the main points of powered exoskeletal armor that a human being is currently a lot cheaper than a computer system to replace, or at least in terms of insurance, etc.?

The energy thing is interesting, but are you talking about carbon nanotubes? when you're talking about lonsdaleite?

I think we're going to see a space elevator before some "super" material in commercial use.
