@ProPainC63 mate, if your going to insult people like that, you need to hide your Youtube profile photo, you cant insult how people look when you have a head like yours, nice tits too by the way. I assumed you were a kid as someone your age should be able to tell fake footage from real, but then I noticed you were American and it all made sense.
@unapro3 I have nothing to hide fat boy. I am in better shape than you could ever dream to be in. Tits? LOL. Tits are the gelatin like masses of blubber affixed to your torso. What you see in my picture are called pertoral muscle. Yes, I am an American "mate". Proud of it. Australia right? No wonder you follow other countries military achievements. I understand "mate" I hear there is a kangaroo race planned for later today. Better leave now.
@unapro3 I I I....I have you stuttering. LOL. Not even close to the best I have but obviously enough to get a rise out of a mental midget Aussie like you.
This video was made for the representation of how a certain projectile looses its accuracy and starats tumbeling if the rifled barrel or stabilizing fins are not used....
I read in the comments on a similar vid that the camera stays still and a mirror reflects the image and the mirror aims on the shell using a radar tracker.
@poopipeplunger Somehow I'd have guessed they would use the shell's known velocity to calculate it's expected position along the shooting range for the mirror to look at.
Almost. Usually the mirror simply spins at a pre-programmed rate. You know where the camera is. You know how fast the projectile will be going (within reason). Therefore, you know how fast the mirror needs to spin. Much simpler/cheaper than anything like a radar tracker.
in this video, the camera tracks the round after exiting the barrel. i understand that a high-speed camera can view high velocity objects because of the high rate of frames per second, but who or what was moving the camera fast enough to actually track the round upon being fired?
@themasonaux If the video isn't a fake then I think the camera is placed far away, a distance that allows to take with small movement large areas of space. well then to frame the projectile have zoomed (XD sorry for my bad english)
@themasonaux a good telescopic lens , allows the camera to be far away, mounted on a motorized tripod, then its a matter of calculation..... not the most difficult thing to do with todays technology.. :)
@themasonaux All you need is a camera with a lot of zoom, that is far away. This will decrease the amount of movement (and gives need for a very precise movement control)
@themasonaux I highly doubt the whole camera is panning that quickly, its probably a spring-loaded, precicely timed mirror which "snaps" to track the projectile like a mousetrap, reflecting the image down (or up) to a stationary camera.
This is not fake. It is a blank slug travelling at 700m/s. They say "it's done with mirrors". This one is! See "MS Instruments Flight Follower".
This one is actually pretty old - around 10 years ago. Our newer videos are even better, although nothing beats monochrome for clarity. If you really want some fun, see if you can measure the velocity from the cone angle :-)
its not fake... the reason why: its propably fired from a non-rifeled barrel. so theres no spin... second possibility is the quality of the video... even if it would spin we wouldnt see it :)
its actually not fake im confuzled as to how they were able to track the bullet but you can see the air pressure build up infront of it as well as behind it causing a half circle. also the exlosion from the tank that shot the shell was definetly real i use 3ds max alot and can tell its not fake perhaps they mounted the camera on a remote tripod attacched to a motor and synced it so that it would follow the bullet.
@perspicacity89 The camera isnt turning, the camera is looking at a mirror which is specifically timed to spin at the rate the projectile will pass. Not fake.
Fake. The army doesn't use flat nosed projectiles. And why would they take video of something so inaccurate that it's tumbling within a hundred feet of the muzzle. Get a new job.
Computer controlled camera: You know when the round is fired, and how fast it travels. You also know how far the camera is away from the path the round is taking. It's actually pretty simple geometry/physics
@ViperVenom16 The camera is in fact a type of high-speed panoramic camera, designed for high speed motion capture such as bullets or rockets. It doesn't need to follow the shell, the different camera angles it has 'follows' the shell.
The shell you see, is (if Im not mistaken) a training shell, not designed to be used in action, but to familiarize the crews with what actual firing is like, not target practice. It's got a poor ballistic design, so as not to be a threat if it flies past the range.
@vava54own exactly.,... without a doubt it was a electronic high speed camera that tracks what its filming itself.... anyone who thinks the us millitary would have a guy standing beside a tank firing with a camera on his shoulder is retarded... the camera that filmed this is probably worth more then $200 000
@pieroog shows what u know.... the m1 abrams uses a smooth bore cannon... that means the round comes out with nearly no spin on it.... the round used in the video is a testing round, to see how many GS and how fast the round can be fired, a normal round would be more aerodynamic
@pieroog The new barrels on the Abrams is a German smooth bore. The projectiles are more like arrows than the typical projectile that we normally think of.
However, this is a fake video. Obviously the makers of the video didn't take into account that the sabots fall away from the projectile the instant it exists the bore, and the army would also not use an obviously unaerodynamic projectile.
@aydoooo ya. but i did find out how they do it. they have the camera point at a mirror and put the mirror on a eltric mottor and when the shell is fired a singnal is sent to the mortor to make it folo the shell
I believe the camera is aimed at a rapidly spinning mirror, which allows for incredibly rapid rates of panning. How they synchronize the mirror to the projectile however, I do not know.
@fanofCOH Possibly, but that would cause a lot of shakiness, not to mention the difficulty of getting a telephoto lens to let enough light in and remain focussed etc etc. Easier to use a rotating mirror.
@Insomniac535 i suppose, ive always e been fascinated by these amazing pictures and slow mo's. if you got the real answer as to how this is done then id be much appreciative.
how i think they fimlmd it was with a very wide camera shot and then just croped and zoomed in to were they wanted to watch the projectile.............im preaty sure
they didnt, they just film a gun with only a sound, then they move the camera very fast and slow motion it, coz the bullet is obviously soo slow in this vid
love the air pushing in front of it and why the fuck do you always get some shit head who thinks he is a fucking US marine going on about weapons, STFU
thats a 155mm anti-personel air burst round. its a round that detonates at a set height from the target area. its filled with .50" ball bearings. all it really is, is a really big and "smart" grenade.
well, they are related... the wave in front is a pressure wave caused by air moving other air out of the way of the projectile. sound is a pressure wave, so that wave cannot travel faster than the speed of sound, so the object (if going supersonic speeds) will catch up to the pressure wave and "break' the sound barrier.
I understand the concept just fine - my comment was regarding semantics.
Something exceeding (or nearing) the speed of sound creates a shock wave (as in this video) and is said to "break the sound barrier". The term "sound barrier" is an imaginary concept used to describe an observed phenomenon, like "glass ceiling" or "black hole". The terms are related, but a shock wave is not the sound barrier any more than gravity is a black hole.
The term "sound barrier" was coined to describe the inability of early jets to exceed the speed of sound because of dangerous buffeting, thus the "barrier" was a metaphorical one, not a physical one. To call a shock wave a literal barrier is incorrect. Sorry to be such a nit-pick, but to an engineer using terms correctly is essential to avoid confusion.
barrier does not imply it cannot be passed through or is solid. it can be an object that impedes movement in any way, even just slowing it down. if that wave is at a higher density than the surroundings then it would (by a very small amount) slow down objects (more mass to move out of the way). so technically, it is a barrier.
The projectile is supersonic. That shockwave is only created by an object travelling at supersonic speeds. It can't possibly 'catch up to the pressure wave'. I could bore you and myself all day with external ballistics.
tesm but i am talking about when an object is accelerating to supersonic speeds, the pressure wave created by subsonic flight is can travel at the speed of sound. (pressure wave=sound wave as you probably know) so when the object surpasses the speed of sound it catches up to the pressure wave. look at a video of a plane breaking the sound barrier you can actually see it happen
there is a pressure wave even if it isnt going supersonic. the distance between the tip of the projectile and the wave decreaes with increasing velocity. when it catches up and surpasses that wave, it "breaks" the sound barrier. however, the shockwave from a supersonic projectile is different in shape and such. we study aerodynamic flows lot in aerospace engineering... if you can go > mach 1 you CAN catch up to a pressure wave if you accelerate from subsonic to supersonic speeds
That shell does not have rifling - it IS possible for it to turn that way. With some of the radio guided cameras, it IS possible to track the shell with a camera.
No, the majority of tanks are smoothbore; they use both rifled and unrifled ammunition, including sabot-carried rounds with stabilizing fins that cannot be fired from a rifled barrel.
they showed how they did this on the bbc... the reason the shell tip is not coned as you would expect was because they were showing the unstable flight and ballistics of a flat tipped shell... there is another video that followed it in which they used a conventional cone tipped round. (but this one i cant find on youtube). and they used a camera shooting at over 1million frames a second... and the image is reversed, the camera stays still and a timed mirror is what moves in front.
its real if you stand on the eifil tower and pan a camera realy quickly across paris you will see like 30 miles in 1 second they just have a machine that perfectly timed with the firing of the shell anyway how could they make special efffects so good? eh...
one question. why, when people get the chance to vent their spleens do they do so with such avid aggression. Cogent argument does not require you all to swear at each other. fuckwits. haha...
Look at all of these douches, they think their smart writing their paragraph on why this video is fake, well guess what, you guys can fuck yourselves.
so are you saying that a barrier is not something that impedes movement? of course there are multiple connotations for the word "barrier" but a pressure wave could be considered a barrier. although not by the most common connotation. anyways etymology is the HISTORY of a word which is not what we are debating.
If you want to call a pressure wave a barrier, be my guest.
If you want to know why a pressure wave is not a literal barrier in the context of the "sound barrier" - or any other - then you should look up who coined the term and what they meant by it (etymology). Until you do that, you'll just have to take my word for it.
so what qualifications do you have? an aerospace engineering degree? any education in aerodynamic flows and/or fluid dynamics? most likely not. the original meaning of the word doesnt matter,what does is its uses in modern english, one of which is anything that impedes movement, which a pressure wave would. its not what comes to mind when someone says "barrier" but technically it is one. talk to someone with a phd in aerospace with an emphasis in fluid dynamics/aerodynamic flows
lol, just because you're all too dim witted to know how something is done, DOES NOT mean it is fake. For your information, the camera is sitting still. But it is aimed at a mirror that follows the shell, guided by a radar tracking devise. What you're seeing is a reflection.
cgi is great isn't it? bullets (and shells) do not travel like that. and cameras cannot pan, zoom and focus at the same time on an object moving this fast. nice job on the shockwave, but wouldn't the shockwave slowly dissappear as the bullet accelerates to a stop? (yes i said accelerate, go look at the definition of the word before you get all typecrazy with your dickbeaters
its not a guy that would be impossible, they calculate how fast the shell goes from start to end and punch in the numbers so that a "robotic" tripod pans steady with the shell
one of my friends who is a soldier had a part of the skin on his forhead ripped off when a tank shell went past his face. These things are not only dangerous when they hit but dangerous when they pass by.
It would be travailing at significantly higher speeds than a couple of hundred miles per hour I think you have underestimated by a factor of 10 or more!
look above and below the shell between 00:03 and 00:12, you could see the shock wave. at the angle, the shell had to been going at least twice the speed of sound.
wow look at the wave around the shell

well, they are related... the wave in front is a pressure wave caused by air moving other air out of the way of the projectile. sound is a pressure wave, so that wave cannot travel faster than the speed of sound, so the object (if going supersonic speeds) will catch up to the pressure wave and "break' the sound barrier.
cooptroop123 2 years ago
I understand the concept just fine - my comment was regarding semantics.
Something exceeding (or nearing) the speed of sound creates a shock wave (as in this video) and is said to "break the sound barrier". The term "sound barrier" is an imaginary concept used to describe an observed phenomenon, like "glass ceiling" or "black hole". The terms are related, but a shock wave is not the sound barrier any more than gravity is a black hole.
Theriomalstrom 2 years ago
true, but since the pressure wave is a physical barrier, one could think of it as a literal sound barrier, since its sound and a barrier
cooptroop123 2 years ago
The term "sound barrier" was coined to describe the inability of early jets to exceed the speed of sound because of dangerous buffeting, thus the "barrier" was a metaphorical one, not a physical one. To call a shock wave a literal barrier is incorrect. Sorry to be such a nit-pick, but to an engineer using terms correctly is essential to avoid confusion.
Theriomalstrom 2 years ago
barrier does not imply it cannot be passed through or is solid. it can be an object that impedes movement in any way, even just slowing it down. if that wave is at a higher density than the surroundings then it would (by a very small amount) slow down objects (more mass to move out of the way). so technically, it is a barrier.
cooptroop123 2 years ago
The projectile is supersonic. That shockwave is only created by an object travelling at supersonic speeds. It can't possibly 'catch up to the pressure wave'. I could bore you and myself all day with external ballistics.
scottyotty2hotty 2 years ago
tesm but i am talking about when an object is accelerating to supersonic speeds, the pressure wave created by subsonic flight is can travel at the speed of sound. (pressure wave=sound wave as you probably know) so when the object surpasses the speed of sound it catches up to the pressure wave. look at a video of a plane breaking the sound barrier you can actually see it happen
cooptroop123 2 years ago
there is a pressure wave even if it isnt going supersonic. the distance between the tip of the projectile and the wave decreaes with increasing velocity. when it catches up and surpasses that wave, it "breaks" the sound barrier. however, the shockwave from a supersonic projectile is different in shape and such. we study aerodynamic flows lot in aerospace engineering... if you can go > mach 1 you CAN catch up to a pressure wave if you accelerate from subsonic to supersonic speeds

That shell does not have rifling - it IS possible for it to turn that way. With some of the radio guided cameras, it IS possible to track the shell with a camera.
What type of round is that?
f38stingray 2 years ago
the barrel had rifling, almost all gun barrels these days have rifling
TheIketastic 2 years ago
No, the majority of tanks are smoothbore; they use both rifled and unrifled ammunition, including sabot-carried rounds with stabilizing fins that cannot be fired from a rifled barrel.

they showed how they did this on the bbc... the reason the shell tip is not coned as you would expect was because they were showing the unstable flight and ballistics of a flat tipped shell... there is another video that followed it in which they used a conventional cone tipped round. (but this one i cant find on youtube). and they used a camera shooting at over 1million frames a second... and the image is reversed, the camera stays still and a timed mirror is what moves in front.
Davidbirtles1 2 years ago 2
its real if you stand on the eifil tower and pan a camera realy quickly across paris you will see like 30 miles in 1 second they just have a machine that perfectly timed with the firing of the shell anyway how could they make special efffects so good? eh...

Look up the term and find its etymology. Calling me a dumbass doesn't make you right.
Theriomalstrom 2 years ago
so are you saying that a barrier is not something that impedes movement? of course there are multiple connotations for the word "barrier" but a pressure wave could be considered a barrier. although not by the most common connotation. anyways etymology is the HISTORY of a word which is not what we are debating.
cooptroop123 2 years ago
If you want to call a pressure wave a barrier, be my guest.
If you want to know why a pressure wave is not a literal barrier in the context of the "sound barrier" - or any other - then you should look up who coined the term and what they meant by it (etymology). Until you do that, you'll just have to take my word for it.
Theriomalstrom 2 years ago
so what qualifications do you have? an aerospace engineering degree? any education in aerodynamic flows and/or fluid dynamics? most likely not. the original meaning of the word doesnt matter,what does is its uses in modern english, one of which is anything that impedes movement, which a pressure wave would. its not what comes to mind when someone says "barrier" but technically it is one. talk to someone with a phd in aerospace with an emphasis in fluid dynamics/aerodynamic flows
cooptroop123 2 years ago
As I said 2 or 3 comments ago, I am an engineer. I took fluid mechanics as an undergrad and finite wing theory for my MS.
Theriomalstrom 2 years ago
lol, just because you're all too dim witted to know how something is done, DOES NOT mean it is fake. For your information, the camera is sitting still. But it is aimed at a mirror that follows the shell, guided by a radar tracking devise. What you're seeing is a reflection.

Yeah right... A camera guy with a handheld, no tripod, no nothing.
That was the fastest and steadiest cameraman in the world folks.... He sees everything in slow motion.
It's dangerous for him to cross a busy road because he falls asleep halfway through.
He also has to shave 10 times a day.

cgi is great isn't it? bullets (and shells) do not travel like that. and cameras cannot pan, zoom and focus at the same time on an object moving this fast. nice job on the shockwave, but wouldn't the shockwave slowly dissappear as the bullet accelerates to a stop? (yes i said accelerate, go look at the definition of the word before you get all typecrazy with your dickbeaters

ScopedOUT2 2 years ago
in an artillery piece, the projectile is known as an artillery shell.
you are most likely thinking of the shell casing that is jettisoned from the rear of the barrel in a small arms weapon.

It would be travailing at significantly higher speeds than a couple of hundred miles per hour I think you have underestimated by a factor of 10 or more!

look above and below the shell between 00:03 and 00:12, you could see the shock wave. at the angle, the shell had to been going at least twice the speed of sound.
