Yeah. You would still most propably die.
i'd assume if they market this as a safe solution then they have to manage the energy somewhat. From the picture it seems like the outer shell is going to bounce off on impact, maybe that makes sense?
no.
moron here, would it really? i imagine a bullet hitting and being stopped by a helmet would transfer the same amount of force as pressing the buttstock of a rifle to your forehead and firing, which would be unpleasant but i assume wouldn't kill you.
the reason your buttstock doesnt kill you when the bullet does is because the bullet is accelerated "slowly" over the time its in the barrel as opposed to accelerating straight to zero because it hit your torso
and surface area matters too, a buttstock is much wider than a bullet
but you are right that a helmet designed to stop a 7.62x39 round wouldnt kill you
a helmet made of rigid material with padding on the inside would slow the bullet down gradually and spread its force over a wide area
unless the bullet has enough force to snap your neck from the impact, you are going to get maybe a concussion at worst
>i imagine a bullet hitting and being stopped by a helmet would transfer the same amount of force as pressing the buttstock of a rifle to your forehead and firing
The issue becomes backface deformation. Helmet has to be light enough to not break your frickin spine. Which leads to the situation of "wow yeah you stopped the round but caved your skull in six inches" which is a problem.
Totally normal. These things have existed for years.

Getting severe head trauma that you might recover from is different from having a gaping hole in the back of your head.
Your noodle is liquid in both situations dingus, a 5 inch backface deformation means your "lifesaving armor" is now sharing the same space as your brain itself.
Id rather die than suffer that much brain damage tbh
>that you might recover from
why do people always overestimate shit like backface deformation and 'energy transfer' through armor? there is plenty of evidence of people taking head/body hits from rifle rounds with armor and walking it off. Sure it can be bad but just because some helmets/armor at some ranges against some ammo at some angles can produce lethal backface deformation doesn't mean it doesn't save the wearers life more times than not if it prevents penetration. I think its caused by armor review videos showing a dead-on hit at 10 feet and going 'yep... that's a lotta backface deformation' and they just think every possible scenario is like this. Armor is tested at pretty much worst-case scenario, that is how NIJ standards are made.
Helmets are different than plates. For one, there is no current NIJ test or certification for helmets. Hasn't been since the 80's. And that test amounted to
>PASGT good
Military helmets tend to be self certified by the contracting agency. Army will set requirements and will test them itself. These specs and test results are not always publicly available.
So there does not exist a correct test standard for an official registry or for autists like buffman to test and post. People are going to do the best they can. I have seen a few attempts using those ballistic gel heads, and it almost never goes well. They are pretty fragile. But so is your noggin. You dont have a lot of tissue between your skin and skull to take up energy. So it stands to reason its far more vulnerable to BFD than your chest is.
>there is plenty of evidence of people taking head/body hits from rifle rounds with armor and walking it off.
Sure, there's also people who have been shot in the head unprotected and survived and even fallen out of fricking planes and lived. We call these anecdotes. While they may very well be true and even can be verified they are not scientific and not something you can base performance off of. Yeah people have survived rifle hits. What was the cartridge? What was the range? Angle? Muzzle velocity? Temp? Humidity? Is it even remotely repeatable?
shooting an empty helmet will look different than having a skull behind the helmet.
your head is surprisingly resilient against blunt force trauma
Helmet weight issues are even more severe than body armor weight issues, to the extent that many special forces don't even use pistol rated helmets, just glorified bike helmets
why the frick don't we have shoulder-supported helmets yet?
mobility, bulk, weight, long-term creature comfort
Because that way lies silliness

FTFY
Like a great bascinet?
We do.
ECH has stopped 7.62x54
You guys are fricking stupid honestly
So have WW2 tin pots
At what distance and angle
Yeah, the okraina war brought so many noguns morons, it's fascinating.
Like this guy
>he doesn't see the ricochet smoke
he didn't get a direct hit, noguns homosexual
Yes, I'm sure the bullet lost a lot of energy slightly clipping the edge of the brick.
>glancing shots
>stopped
implying
>noooo you can't say a helmet stops bullets just because it stops bullets
>what if the rifle was pointed directly at your face from 5 feet away
>stop saying protective gear worked in the situations it was supposed to
Post'em.
Im a 2016 election has guns european tourist.
Gee, the largest fricking war in Europe since WW2 is bringing more people to a weapons board. What a TWEEST! Not to mention a war in which Western equipment is finally able to truly be matched up against Russian equipment to determine which is superior, and gee, what a surprise, it turns out Western equipment is better. I feel vindicated after all the years on /k/ of arguing with moronic Vatniks who would constantly screech about how "tough", "rugged", and "durable" their equipment was compared to Western equivalents and how their unupgraded T-72's could easily kill an M1A2, blah blah blah.
As someone who was here in 2014 for Crimea, it's nice to see the Ukrainians genuinely improving themselves since then. Ukraine has obviously always had a problem with corruption and a weak economy, but they're primed to be one hell of an investment opportunity at the end of this war. You're going to have businesses the world over wanting to expand to Ukraine to rebuild and invest into the country. They're likely going to become a fairly decent European country within the next 20 years.
it feels like a hollow victory when you realize these people really are that stupid. there's no secret, no event in your upbringing that differed from theirs, they're just moronic
Frick off, you weren't here in 2014. /k/ back then was fine with Russia memes back then, stuff like Motorola with the coffee mug was a classic for years. 95% of the shit being posted about the war isn't about objective capabilities of certain weapon systems, but really low tier garbage of spamming videos of people getting killed or the latest screenshot of some liked or disliked personality from twitter, not to mention the garbage of people reposting literal tabloid trash from the UK as if it was real.
People liked Motorola and Givi but their support died with them
Yeah, we enjoyed Motorola because he was entertaining not because we supported Russia.
Gee, almost as if that wasn't even the point.
Contain your butthurt Mykola.
He must be slow or something... I remember when I was deployed this one group was talking about how they left their moron in a house and called an arty strike on it
Luckily I had nice mates who didn't do tha
>t.moron
Yes. Modern HPE helmets can. The problem is they have more BFD than kevlar helmets. With kevlar its the other way around. Much less BFD but more easily penetrated and defeated by AP rounds or rifle rounds.
>BFD
Back face deformation?
Yes. lookup some of the helmet tests Oxide has done over the years and you'll see how different materials will behave. Polyurethane helmets seem to trade rigidity for penetration resistance. It means they can stop rifle rounds but depending on the angle your melon will be caved in anyways.
Poles being capable of this tech is dubious. Is it possible for humans? Yes, opscore already has a helmet that stops 5.56 and 7.62x39
The first ballistic vest was invented by a Polish man and Kevlar was invented by a Polish American woman.
Dipshits in this thread that lose any sensibility when helmets enter the picture
>specops exclusively use bumps bro
>IIIa will already turn you into a vegetable
>5 inches of backface deformation bro
Meanwhile Ulbrichts has a VPAM 6 helmet that keeps residual energy below 25j. helmets stopping rifle threats is no different than plates, there are just tighter energy management tolerances.
Shooting an unsupported helmet with nothing inside is very far from realistic, its akin to shooting soft armor unsupported without clay, and saying "OMG GUYS IT FLAILS 200 INCHES BACK IIIA A MEME"
india's patka helmet can stop 7.62x39 from the front.
>trusting india
Ngmi
Yes. This is 7.62x54 from like 10 meters away. You're going to get head trauma, but nothing worse than what people get from football or boxing.
He wasn't even knocked out by the hit.

> "I had no surgeries. Basically, the eight days that it took me to get [from Germany] to Fort Benning [in Georgia], the brain bleed was healed," he said. "Other than some physical therapy to correct some balance issues, that's the only treatment I've had."
Why does /k/ go full fuddlord tier on armor? They still think you get broken ribs if you get shot in plates and that 7.62x39 can't be stopped by a helmet without BFD killing the wearer.
When will you morons realize it is the current year and we've had armor that can take hits for decades?
He literally had a brain bleed you moronic mongoloid. That would have killed him had he not had modern medevac.
And without helmet medevac wouldn't help him, tard
ask your neck if he can handle the force of the bullet being stopped by the helmet
plus a possible concussion?
>ask your neck if he can handle the force of the bullet being stopped by the helmet
Yes. Of course it fricking can. We have many examples of exactly that.
See
for just one of them
Which is worse, 7.62 through the brain or a concussion?
Motorcycle and football helmets are utilizing a system called mips which allows for some small amount of slipping when the helmet is struck. The outer shell slides over an internal structure with the idea that it'll dissipate some of the energy.
Would this be viable with ballistic helmets?
No because mounting accessories to the helmet would cause the MIPS system to "slip." For MIPS to work, the helmet can't be a stable accessory mounting platform.
My Bell motorcycle helmet has some meme technology thats supposed to mimic mips without the slippage, they use 3 layers of various foam density/material to optimize protection in different crash conditions. I dont think any of that translates to ballistic helmets though.
Yes. Ignore
, he doesn't realise the system can still be stable outside of heavier hits.
This thread is full of morons that overuse fuss and talk out their arsehole.
Have you even seen a MIPS system, moron?
And have you ever worn a helmet with NVG + counterweight? MIPS would be absolutely worthless on a combat helmet.
Does it have a support system in place for the whiplash you’re going to get from getting hit by an x39 round? Cause it’s gonna break your neck.
There are multiple examples of that happening earlier with no broken neck and not even a knockout
helmets aren't weapons, this thread is off-topic.
Shut the frick up Taras, you have plenty of offtopic threads. Read the rules of the board while you're at it.
>maximum ivan unlocked
We've had helmets that cant stop 7.62 for decades. the problem is they're too heavy to be useful, and the kinetic energy transfer can break your neck and kill you anyway
>break your neck
No chance unless you’re clinching very very hard. Deformation is the more potentially lethal part and it’s not even certain, especially if the bullet gets deflected a bit by the exterior due to the helmet’s oval shape
fully moronic post
Forgive me of this is a stupid question.
Why dont ballistic helmets use tech that is found in bicycle helmets, like MIPS or Wave Cell?
>claims to have developed a helmet that can withstand 7.62x39 round
You mean the ECH, that's been a thing for like 13+ years now, and is being issued all around the US armed forces?
we have had level III helmets capable of stopping 308 for years
we now have helmets with level IV appliques
7.62x39 is not a particularly difficult threat to stop
Is nobody going to mention that this is literally just a rebranded Ulbricht helmet?
Yea, why not? There are even level 4 helmets?
>There are even level 4 helmets?
There are not. There are literally zero level IV helmets. I know that for a fact because there is not even a level IV testing protocol for helmets, much less any that meet the standards of a nonexistant protection level.
Yes. Deformation is ussually (might find exceptions) catastrophic but many times more survivable then a remote craniectomy
now with extra concussion and broken necks!
>broken necks!
Not when it's paired with passive neck supports!
You have a single case where a neck was broken or at least a scientific theory as to why it would be?
I'm sorry anon, you're right, I couldn't find a single case of a neck every being broken, I was wrong....
