Russia claims their new future body armour will stop a .50 cal
 

Hmmmmmmmm...

Will the Opposition Leader be demonstrating its effectiveness? :hmm:

No, he will be demo-ing it's early teething problems.:E

Wont stop a .50 cal blowing your arm off.

From a US website discussing ‘how a .50 cal kills you’...

With a .50 machine gun it's unlikely to be just one round that hits - depending on the particular weapon the rate of fire is 400 - 1200 rounds per minute.

The laws of physics do not apply in the US as Mr Newton didn't get a visa.

Not according to this gentleman who, despite his obvious ancestry, I believe was American...

So maybe sometime in the future the momentum of the .50 cal going forward will equal the recoil going back towards the shooter. I guess at that point our US cousins will stop shooting .50 BMG from a big rifle.

James Doohan was Canadian. Landed with 3rd Canadian Inf Div on D-Day and I believe he flew too.

momentum same in both directions
 

It always was the same. It's the kinetic energy that kills you.

Imagine a ten pound gun firing a one ounce bullet at 1600 feet per second. It will recoil at ten feet per second. Momentum is 10*10 = 100 foot pounds. That's also true for the bullet 1/16 *1600 = 100 foot pounds.

Kinetic energy of gun is 1/2mv^2 (5*10^2) = 5*100 = 500 foot pounds.

Kinetic energy of bullet is also 1/2mv^2 (1/32 *1600^2) = 1/32 * 2560000 = 80,000 foot pounds. It's 160 times as much.

I don't know the actual values, this is illustrative. The recoil will also include that from the high velocity gas propelling the bullet, but I believe recoil suppression devices vent much of the gas backward - at the cost of making the gun even louder. I have never fired anything bigger than a 12 bore shotgun, and that is loud enough for me!

Maybe it will, maybe it won't....but underestimate the Russians at your peril...as the SU-57, continued space program and the Sputnik vaccine show.

a fifty ball plinking into your armour is going to flick you away like lint, it may not penetrate, but being booted over the next county might not end well.

I'm thinking spalling... your tummy is going to have the wobbles as is every cavity of your body. The Ke is roughly the same as a 300lb mass running into you at 100kmhr, with a pointy stick that is 1/2" across. The bullet may not penetrate the vest, but the vest may penetrate the person wrapped around the bullet. gonna leave a bruise.

the 50 has about 18-20kJ of kinetic energy. per standard

Staying Power.
 

Their Sputnik satellite has gone a bit quiet, lately.

Your energy calc is erronous, 20kJ is 110lbs@100kmh or about 2 large dogs@1100 inches/second . . . probaby knock you over . . .

Armaments suppliers are pretty consistent, offering something that is not necessarily needed or capable of being used/ As long as it gets the Dollars / Rubles / Euros or whatever currency then the end justifies the BS.

I saw a show a while back where they were demonstrating the US Army's 50 cal sniper rifle. It was punching a hole through half inch armor plate at something like 500 yds. I also seem to recall they have an "armor piercing" round for the 50 cal machine gun. Hard to believe they could come up with body armor that could stop that - at least body armor that anyone would be able to wear and still move...
Maybe the Russians are re-defining body armor as a small one person tank :ok:

I thought Boris was a bullet dodger ?

Sure .... it’ll probably just deflect the round .... right up his nose!

Very efficient use of propellent (?) which if ignited in a bowl in front of you would be harmless(?)

Mjb

I was wondering when someone would ask what this body armour would look like. Something that can withstand a .50 cal may not be too portable.

Now that we all want Sputnik V they’ll be able to make him have a terrible accident without too much fuss from our governments.

Maybe a BMP propelled Fred Flintstone style?

How thick is it - couple of feet?

A fired a Barrett at a range in Vegas and it was like being in a closet with a thunderflash. Bejesus!!

Even if true, it will have some negative affects. That helicopter that could carry X number of soldiers is now at X minus some number. That meaning more helicopters are needed or fewer soldiers are available, same for vehicles, etc. That means a greater logistics/support tail and so on.

Russia claim their new future body armour will stoo a .50 calibre
 

I am afraid they are away with the fairies. I remember not too long ago a U.S SPECIAL SNIPER USED A BARRETT M82 50 CALIBRE ..NOW GET THIS.
HE TARGETED A TALIBAN AT ALMOST 1 MILE AFTER MANY CALIBRATIONS TI HIS RIFLE AND TAKING INTO ACCOUNT TEMP. PLUS WIND SPEED.WHILE AIMING ANOTHER TALIBAN WAS STANDING BEHIBD TARGET.
TRIGGER PULLED ..RESULT 2 DEAD TALIBAN, BULLET WENT RIGHT THROUGH ORIGIONAL TARGET.
IT WA RECOGNISED AS THE LONGEST SNIOER KILL EVER RECORDED. YGE M82 WEIGHS APPRIX 30 LBS AND THE RECOIL IS DEVASTING
IF THEY THINK THIS BODY ARMOUR WILL PROTECT THE TROUPS. IT WILL BE LIKE SHOOTING FISH IB A BARRELL FOR SHrpshooters.
KEEP SAFE GUYS.

Might be better to wear Teflon coated silk shirts in various shades and hues . Hoping for a through and through effect .The Teflon might aid the passage of the round through the body before the projectile could give up or transfer the energy to the surrounding flesh or bone . Just mitigating the effect of the round , so all you have to deal with is a very large transfer hole rather than the explosive carnage created by the energy transfer hydrostatic shock that can inflict devastating wounds . The type of wounding that was mentioned briefly in the Geneva Conventions limiting the types of ammunition’s that can be used against humans.

No real issue making a strikeplate that can stop a .50BMG, stopping the spalling that will occur from the hit could however be a problem.
Hit will likely break some ribs but I'd rather live with that than a .50 hole in the chest!
Here's a wearable plate stopping a .50 API round from up close.
As for knocking you on your arse, note that the carrier + one cinderblock only moved a few inches from the hit ;)

So there’s no hole in the body
 

Big deal, but easier for the undertaker

Broke a concrete block and imprinted the inner lining onto a block of wood - perhaps a soft little human would not have fared very well from that hit.

Dang if I wasn't wrong, Fergusd, am I married to you?

anyway


Fergy is right... have a look at the crash test dummy, and the movement. The Hornady 50 750gr A-MAX is around. 15.2 Kj, for this test and that barely moved. The dummy does have an imprint on the skin from the writing on the armour inside, but if a new tattoo is the only thing that happens, then that is pretty impressive, the shot to the head of course is less fun.

Lots depend on the round fired though, stopping a regular fmj vs stopping something like a Raufoss Mk211 or SLAP round is a world apart!
Just don’t forget to remove the muzzle break if you intend to use SLAP rounds or things could go wrong!

As for backface deformation, armour is usually tested with a clay backing to capture the imprint.
Last one I wore was rated to .308AP, ceramic with some metal backing from memory. 10m test shots didn’t even dent the back.

I think the actual term is 'Salad dodger'.

Whats with all caps? Anyways you are wrong. The longest ever sniper shot has been attributed to a Canadian special forces operator.

Impressive armour. Quite a lot of energy dissipated in smashing a breeze block though and I wouldn't want to try it myself! Very different behaviour to an elastic chest wall which dissipates some energy in deforming, so neither the block nor the test dummy show us much about behind armour blunt trauma injury. I imagine it would be Seriously Ouchy. Interesting read about body armour testing here https://www.nap.edu/read/13390/chapter/10#175

But I'm impressed by a plate that stops a 50BMG penetrating from so close.

I don't think that the design is to protect the wearer from a .50cal. It is most probably intended to be very effective agains more conventional infantry weapons such as 7.62 on an AK47. They just happened to find out that in certain circumstances it may block the .50 cal as well. Hence the propaganda.

Silk is one of the strongest materials to use and has been used in body armour for years, in fact if one certain person had bothered to put his on, WW1 might not have happened.,

If this is the stuff you can pick up at Walmart, presumably the "real" stuff is even more impressive?
