Bullets vs Propeller in Slow Motion - The Slow Mo Guys 

Casey Ellis that's awesome

i like pizza

Casey Ellis spins faster than a jet engine, crazy!

Really?! That's immens! Didn't know bullet spin so fast! Is that normal?

Casey Ellis damn

Nah thats activision

Or the video isn't what was promised and then they call us all entitled cry babies.

"That I wasn't there...."

But, wouldn’t only shot the propeller in the same place?

@@iedi3 Yeah, but that would still be enough to destroy the propeller.

@@iedi3 If’s the synch gear can jump once, it can do it again much more easily

they show it in the video what happens.

This happened a few times. The one I can recall is the synchro on the israeli S-199, which was basically a german bf109 with a german bomber engine

Isn't that the thanos truck

Cybermat47 the British decided to make a pusher aircraft which was actually fairly decent. They also made some sort of monstrosity with the gunner sitting in front of the propellor on a gondola (or 'pulpit') with the pilot sitting on the other side, that was less successful for obvious reasons,

Cybermat47 edit the decent pusher design was the DH. 2 it won airsuperiority over the Somme. the bad one with the gunner risk of losing limbs in propellers was the Be 9

I've seen the picture you're talking about, scary stuff! It was a P-47 that took flak (if i remember correctly) directly to the prop. Massive hole left in one of the blades big enough to stick your arm through.

I heard the metal plates would sometimes cause the bullets to ricochet back at the pilot resulting in death or injury.

Cybermat47 If I recall correctly, it was the Germans who invented this technology.

Not the actual barrell its a fake heatsink to make it look more like vickers mg pay attention to what they say smh

@@m.j.a7704 yeah a heatsink that has barrel heat and is standard knowledge of no touch can be hot

@@pyrocryptic29 dude its based on m60 it used vickers heat sink but when you think about it the barrel size and fit is different the vickers heatsink is not even touching m60 barrel is there only for the aesthetics

M. J. A you ever heard of this thing called thermal conduction? Metal does it, it’s where heat disperses through an object, and good conductors like metal disperse the heat very easily allowing them to heat up very quickly, the fake jacket is in contact with the barrel so it heats up just the same, and because the heat sink is fake it carries no water so has no actual cooling factor. It’s just like him touching the barrel unjacketed, learn basic physics cat shagger

Ah, must've been army. I never saw him eat crayons so he wasn't a marine.

Candi Soda whose gonna pull the trigger two people wouldnt do that its two risky

and the angle to get the bullets to collide would be way to difficult to find as well

marcus james not impossible tho, and a person isn't required to fire a gun

Laser sights and remote triggers have existed for quite a long time. That's generally how companies will test firearms before releasing them for public use.

Tom Haflinger ah, smart. I was thinking it should be after the blade to reduce the risk of impact, but that makes sense.

Total guess, though. They said they slowed the propeller down. I wonder if it works out differently when the blades are moving faster.

Tom Haflinger if you guys find out for sure mind sending the link? Great minds guys

A cursory search for "synchronization gear" and "turbulence" doesn't turn anything up, so it could be a coincidence. If the gear can be adjusted, experimentation could shed some light on this, seeing if firing earlier or later affects the accuracy. The one tricky thing, though, is that the mock engine is stationary. The propellers are without a doubt creating turbulence, but relative to the bullet trajectory, is that turbulence comparable to what might be encountered in real flight?

Really the gun can go off at any time between the blades. it's about the speed of the machine gun not the propeller. It's basically a small cam that disables the gun while the prop is right in front. Other than that you can pull the trigger and fire away in the middle, the tail edge or leading edge, doesn't matter.

BRUH

The experience is idiotic. The propeller never turns so slowly. At high speed, the holes can be completely different, up to the blade tip.

I remember reading that also. It made a huge difference in the hit/kill ratio.

Correct. Note: It was Fokker who invented the "Interrupter gear" for the Germans. Probably the Allies discovered it while poking through some wreckage. Or it was parallel development.

adavidmundt You mean synchronization gear. It didn't prevent the gun from firing, it actually fired the gun itself.

No, the Synchronization gear was someone else (and works as you describe) - the interrupter gear was invented by Fokker, it was just a much worse concept than the synch gear

Panzerkampfwagen He was called Roland Garros. He was NOT killed after he downed his plane due to completely unrelated reasons. His plane was actually captured and studied by Anthony Fokker who tried to improve this system. He became a P.O.W. throughout most of the war but escaped. He wasn't stupid either.

Even if it’s not loaded I’d still be scared to go anywhere near to the front of that thing

Exactly

Is he? He's standing on the far side of the propeller while it's more or less straight up and down and the gun should be centered on the propeller. His left elbow is against the far side of the fuselage. If his head is in front of the gun, that would mean his right elbow must be straight in front of Dan relative to the engine which doesn't seem to be supported by the rest of his positioning. I won't deny that it looks like his head is lined up with the gun but I think that's a perception issue....

Why? It would be interesting to stare straight through to the barrel of an m16

They are ALWAYS loaded

Because im, BATMAN! it was making me a little nervous to!

Because im, BATMAN! Good call, pretty unsafe. I love this channel, but that made me a little nervous. Not an anti gun lefty, btw.

Gun was out of ammo, and it was declared range safe. No danger. He's not standing in front of a loaded gun.

Rage safe is a great way to describe it, tbh.

pretty sure he's been on set with explosives and guns already, he's young but has experience with filming and gun procedures I imagine

Hassan With 20x13??? You couldn't see anything cuz the resolution ;D

Philipp Walder sorry I don't understand this stuff. Is there anything slower than 120,000 fps that you could get?

Hassan Yeah there's a camera out (NOT commercial) that can see the light in motion. Search after "1.000.000.000.000fps" on RU-vid

This needs more likes

This is a great idea!

spooky

would't it need to go faster as it's a slow process not a quick one

cfg_Forumic OMG YES!!

so what?

I think "in the background" is an important part of that. It's being in the line of fire that's the dangerous bit.

+Völundr Frey i guess, it's just weird they came all the way out to the desert then set up right next to a road.

JhericFury Its a shooting range, not the middle of the desert.

+crashandburnbirner i mean, i guess it'd be both, but okay, sure, that works

they did say at the end of the video that they were only doing 200rpm because 1200k rpm would have the prop moving and it would be hard to catch footage of it moving

For the second question: Yeah, it actually would. But since you wouldn't normally fire the guns stationary on the floor you wouldn't notice the difference.

Actually you'd be surprised how much you notice the difference while flying. Whist playing the awesome and incredibly realistic first world war flight sim, Rise of Flight, I have often had to make a decision when diving on an enemy whether to throttle back to give me more time to aim with the lower rate of fire or give it full throttle, hope that I can aim in time and unleash a devastating hail of lead while hoping I won't over-rev and kill my engine :)

AFAIK, the 'trigger' momentarily switched off the autofire while the propeller was in front of the gun. So yes, it did reduce the rate of fire, but not by a lot.

No I'm afraid that is a common mistake people make, that was the Interrupter Gear which would as you say pause the automatic fire while the a propeller blade was in front of the muzzle of the gun. This never worked properly so the Synchronisation Gear superseded it, this would essentially have the machine gun working in a semi-automatic state and every time a propeller blade would pass the muzzle it would send an impulse to the trigger, firing the gun. If the next firing impulse came before the gun was ready (finished chambering the next round) it would not fire. This meant that the fire rate would peak at certain engine RPM counts where the firing impulses and the max rate of fire of the gun reached an equilibrium and then drop as the RPM increased and the impulses came too rapidly for the gun to have cycled the next round, this fire rate would then increase again as the engine RPM increased and so on. This staggering of firing rates is less noticeable in aircraft that used two of the later version Vickers Machine Guns which had a modification that increased the rate of fire (although the name of that mod. escapes me...) but the difference of fire rate between low and high RPM is quite noticeable as the overall maximum rate of fire is much higher. Hope I didn't bore you with all that, I'm a bit of a nerd when it comes to this topic :D

M60 = 7.62 x 51mm, so yes.... but I question your comment. You need 7.62 to finish your chess set but don't know which pieces they'll be? Maybe take a hammer and make a checkers set :-P Plenty of available spent brass at most gun ranges. If your country doesn't have those, then you likely aint gettin' brass.

You can just buy brass cases. They're sold for home loaders with or without the primers. As it's nothing but shaped brass, any country should allow you to order them online.

Because the ak-47 is an overrated weapon =P. Actually though a bullet striking bullet proof glass would be interesting, it wouldn't be as extreme as normal glass shattering, but the ripples and cracks would be cool to see

Err.... no. It would look exactly the same.

exept the propeller would be alot faster

I hope maybe you guys can revisit this in the future with a full speed prop, Not to see if the bullet will hit but how the prop and round will react, Will it make a hole or will the prop be moving fast enough to make a linear hole our gouge, will it knock the round off its straight flight path? If you could get access to someone with a prop test platform you could do it, you would not need the aircraft mounted gun either, just any hand gun or rifle. maybe in the future some time?

John Norris genial

Prime Comedy extremely hard to do

There's an article on Wikipedia that goes into detail.

There are several ways it's been done. look up synchronisation gears or interrupters and there are some very useful diagrams.

I wonder, what is Google?

Well I've got great news for you then! Not once did he put this head in front of the gun. Not sure what video you were watching... Or maybe you were fooled by the angle everytime he was on the opposite side. But either way, and from the 7 minutes of footage that was published here, he never had his head in front of the gun. CLOSE to it maybe but NOT in front.

Alexandr Škaryd same here

Brian Martin what did u want to say my friend?

It's not much to explain just take the speed of the prop and the gun find the highest common denominator inside the guns capacity to shoot and gear it as such.

Yes. While that sounds simple, its not from engineering point of view..

But a plane's propeller rotates and different rpm depending on if you're trying to speed up or slow down or stay level. And the sync would slide in any case, because the engine wouldn't hold an absolutely steady rpm. So you have to have some positive mechanical link between the crankshaft of the engine and the firing mechanism of the gun that holds off firing in the critical time as the blade will pass in front of the muzzle.

That would have looked great. Steep ammo bill by the time it occurred, though.

Patrick Roelant Love RWBY

if you want a failure like that you need to shoot it with a minigun

pikadude1996 or just shoot it for a long time.

I was just thinking the same thing then read your message. It would have made a better video if the prop was moving at full speed. You just need a blade the that cut's through the air but produces no thrust

@@deancyrus1 It would not have made a better video. Both of you seem to forget that the results would be the same at full speed. 200rpm vs 1200rpm the bullet is still trucking on through the prop like it was stationary. It's not like the prop is going to knock the bullet off course or deviate it in any significant way. Like Gav said, they're dealing with "orders of magnitude" so therefore you'd need 20,000rpm to even start to make a difference. _Bullet through jet engine perhaps??_

@@beefcakeandgravy I think the implication if having the propellor rotate faster is that more bullets would have hit it.

@@beefcakeandgravy Thing of it is, if the prop was spinning faster, there would be more stress on the blade, potentially resulting in some more explosive strikes when the bullets hit.

it was slower than it usually would be before the slo motion so they could film it otherwise it would be to fast.

Did you even watch the video till the end when they explain why it couldn't go faster?

MarKay Beats it is called slow motion

Um Ruairidh Davidson um no he even said it at the end its going at 200 when in reality they go 1000

you answered yourself just then.

MarKay Beats no its u

they also have the prop back to front, leading edge should be straight.

Lav Queso *cough cough* demoliton ranch *cough*

Not really. An MG42 fires about 20 bullets per second at a muzzle velocity of 740m/s. This means that the bullets are separated in the air by a distance of 37 metres.

LewdIsao Last I checked he doesn't have an MG 42, otherwise he'd be showing it off every other video.

was just thinking i think there was a mechanism that wouldn't allow a bullet to be fired when the propeller blade was in front of the barrel. Otherwise their propeller would just get shredded

Prince Tae stfu trash boy

DJ VENDETTA heheheh

its way more simple than that, theres a gear stepped with the propeller connected to the gun, thats how they solved it

Normally with the sync gear it would still be fired full auto, just automatically pause when the bullet would hit the propellor. So some would be close some would be far away, the single shot wasn't that effective at showing the power of the sync gear.

@@megamert2848 Wrong, that's interrupter. Synchronisers typically try to fire gun once per prop rotation (if the gun is ready and trigger is pressed).
