Rocket Sled land speed record

[HFLanciaStratos]

This looks like fun. I think I'll make one myself actually.

I mean... how hard could it be (must be read in Jeremy Clarkson's voice).

[TheZingg]

he pulled around 42g when he came to a stop

[lunaticseclipse]

According to wikipedia, the current record holder for rocket sleds stands at Mach 8.5



[jjohnston94]

0:08 - Blah blah New Mexico blah blah Holloman blah blah

[sketchupto3drad]

@efendulov you have ignored the fact that with modern tech it is near impossible to accelerate an object to mach 10 at less than ten thousand meters true altitude. it is even harder to mantain this speed, even if the craft is going at this speed only a tiny fraction of the way. also, if there were a person in it as the video indicates then they would have died because of immense wind buffeting.

[EddieFivespeed]

ok reset it...i want a turn.

[FUCK202]

its mach 8.5 not 9.7 and it still is a record, and its american

[great2beeme]

the fastest man tested on a rocket sled had his retinas detached from his cornea because of the gforce on his retinas while being properly strapped in lol

[TheLazarman211]

looks fun :D

[crazyTERMINATR]

the background sound at the end is the theme song for Judge Dredd

[SixTFPS]

I'd go on it. Could be fun :)

[Pilot853]

@SixTFPS Im afraid that you would die

[SixTFPS]

@Pilot853 Don't be afraid. Just have a nice cold Coke and a pretty lady waiting at the end of the track for me :o)

[SanRafaelSwell]

Still is a record for fasted unmanned rail speed.

[StealthXD1]

man has never built anything that goes faster then mach 10 on the ground you idiot even in space theres was only 1 and plus that rail and guy would just rattle to pieces the guy would be dead by g forces wow youer fucking retraded

[tLlXenonFire]

@StealthXD1 there are rocket sleds that will do mach 12 but nobody's brave enough to test them to that speed ;)

[StealthXD1]

@tLlXenonFire ya right dude mach 12 is like 7000mph ill believe when i see it

[tLlXenonFire]

@StealthXD1 seriously. want me to send you the news article from the sun?

[StealthXD1]

@tLlXenonFire whatever i'm done arguing if you belive that we have then whatever i don't

[phil656565]

@tLlXenonFire yea, that would kill them for sure, but ive seen the sleds, stealth is a tard

[hfcollins]

are you actually serious? do you honestly think this is mach10!?!! holy fuckin shit this motherfucker is retarded

[zqdz123]

that must be very very cool to set on it !

[nealshireman]

at mach 3.5 the sr 71 needs heat shielding, at mach 9.74, wouldnt just burn up with no shielding?

[Pilot853]

@nealshireman Well, the SR-71 was designed to fly at sustained speeds of mach 3.2. The fastest rocket sled went nearly three times as fast, however it only held that speed for a split second before it was stopped

[nealshireman]

@Pilot853 that makes sense

[mikethenascarfan]

this is not the ricket sled record, it is the manned rocket sled record

[Coprocephalous]

I think your Japanese translation needs some work - the mach 9+ was a night shot, with a multistage stage (three, I think) rocket.

Google "HHSTT"

[FOXcorpislame]

hes taking 40 gees

[FOXcorpislame]

USAF colonol

[LeonMC84]

Unmanned rocket sleds that ride on rails have reached over 10,400 km/h (6,462 mph), equivalent to Mach 8.5. The fastest manned rail vehicle was a manned rocket sled, that travelled at 1,017 km/h (635 mph).

(wickipedia)

[LeonMC84]

The Japanese JR-Maglev is the fastest non-conventional train in the world, having achieved 581 km/h (361 mph) on a magnetic-levitation track. Unmanned rocket sleds that ride on rails have reached over 10,400 km/h (6,462 mph), equivalent to Mach 8.5. The fastest manned rail vehicle was a manned rocket sled, that travelled at 1,017 km/h (635 mph).

[Jaazzzin]

10330 k/m is the world record. It is true, not a mistake.

[baschdifass]

it was 1033km/h dude...10330 is impossible on land and especially on a rail :/

[enkrypt3d]

Uh, dude? Not if you have 3 fucking rockets strapped to your back its not... how do you think they get into space? Rockets! Hey now you follow? strap a few rockets to a sled that can't come off the rails and yes it is possible... artard!

[TheGarrettDressler]

mach 1.5 at least. mach 9 = dead pilot and where did you get your facts

[bruceweeee]

duhhhhh

the unmanned sled did mach 9

[mdmf007]

You moved a decimal point to the right. manned sleds have broke the sound barrier, but mach 9 would simply tear it all apart. The japanese had it all buggered.

[robinmitra1]

its hard to believe it moved at that speed without tearing the rails apart

[compdude47]

haulin' ass

[demiro123]

id blow a dude to ride that

[darkknightbob101]

u would die.

[demiro123]

like a gangsta

[88hyd]

i think he was getting late to school !!

so his pap gona good idea..

[ShulberguHomeVideos]

LMAO!! 16km long rail on 10330 KM/H rocket????? C'MON!!!

[darkknightbob101]

aaaaand Go..STOP!

I question the facts of this.

[jacobblack18]

get ur facts straight, it's Mach 8.5 OP (10430 km/h)

[pnero820]

I can't believe they gave Stapp a helmet. Like that's gonna help if the air brakes fail. I can hear the planning sessions now...  "Ok, how are we gonna design the cockpit... eh screw it."

[manbearpig900]

By the looks of it, it is more of a neck support structure than a head protection.

[roshun22]

LOL @ 10 million kilometers per hour :/

[pashaahsj]

lol haha anyone can have a nice cup of coffee at a speed of 10 million kilometers per hour... but its the acceleration that says things about the g-forces and the damage. not velocity.

[turfguy87]

why in God's name would they build a cockpit for that without a windshield to cover their head??? 1000 mph with your head exposed-how stupid

[spasticsurgeon2009]

Really, how much protection would that provide? You'd die anyway at those speeds.

[turfguy87]

wouldn't be for death protection; for regular runs-I'd at least want some wind protection so it didn't blow my face off each time

[Sadetree]

@turfguy87 This was sixty years ago and we needed documentation on the facts! No saine person will ever atempt to break his records. He is a national hero.

[danrieke]

Yyahh... we're gonna need you to, um, climb into this rocket sled here and, um, shoot down this track so we can, um, make room for some boxes... yyahh...

[boobmasteris]

it was about 40 g's. this guy is John P. Stapp, there are many videos of him

[xxbatman31xx]

humans cant go mach 9, if they do there brains and body would somewhat explode.

[hellkid94]

yes we could but we have to build the speed up slowly at about 9-10Gs this got around 100+Gs

[tjakal]

space shuttle does mach 25, speed is irrellevant it's acceleration/deacelleration that can kill you.

[tjakal]

however going hypersonic like this inside the atmosphere would ignite you ;D

[sadekgheidan]

@tjakal Try using your ejection seat at that velocity lol.

[fcguy7]

@tjakal and air resistance/drag ... a lot of sled testing was done to asses the problems of ejecting from an aircraft at very high speed. Otherwise you make a great point.

[Teh1337bix]

@tjakal Yes it does if we're talking about in air. Another video about this test track said that sometimes even metals catch on fire when going that fast.

[tjakal]

@Teh1337bix I keep getting this explained to me every once in a while since my post have been thumbed up a lot for some reason, but if you scroll down to where I first posted this, you'll see I foresaw this objection and wrote "however going hypersonic like this inside the atmosphere would ignite you ;D"

[0mfgitzBiafor3]

they can go mach 9, the black prject aurora does mach 11., they just cant go that fast straight away, you have to build up speed slowly

[Zaphodox]

Not true. DO not confuse mach with g force. Astronauts do many times mach 9 and suffer no harm at all.

[DeArmeStudent]

@Zaphodox

Astronauts never do mach 9, but fighterpilots do...and yes, Tjakal is right: mach DOES kill you...if you hit a tree with a car, your car is instandly de-accelerated, with mach 50, ripping your vessels off your heart...and then you die...

[Coprocephalous]

@DeArmeStudent - "...if you hit a tree with a car, your car is instandly de-accelerated, with mach 50" you really don't understand the difference between speed and acceleration, do you?

Mach is a speedy, related to the speed of sound, not an acceleration.

Orbital speed is equivalent to about Mach 25, but of course, there's no air, so no speed of sound.

[PrivateCustard]

@DeArmeStudent You're getting mach and G-Force badly confused. Mach is speed and G-Force is related to acceleration, deceleration and turning.

[JGMagoo]

@DeArmeStudent You need to get a dictionary and read it before shooting off your uneducated mouth. How do you put 'student' in your name? 1st grade? Age 6?

[blyndrotor]

@DeArmeStudent

You mean G force not Mach. Col John Stapp recieved 40-45G's REPEATEDLY and lived. 50Gs is survivable for a very short time.

[StealthXD1]

@DeArmeStudent fighter pilots dont hit mach 9

[realwortel]

dude, read 2 posts down! the shuttle leaves the earth's atmosphere at 30+ kph and that equals about mach25, no one has suffered from exploding head syndrome yet...

[ambientflier]

It would be fun to ride that at 10,000 km/h. I'd be like "WHEEE".

[Yonkage]

You'd be like... dead.

But it would be fun for the couple milliseconds until your organs were smushed into paste inside you like jello thrown against a concrete wall.

[greenemerald1]

0:59 FTW!! :)

[Baptu92]

U r right amiabledavee, he indeed is Col. John Paul Stapp.

[amiabledavee]

One of the people riding the sled looked like Colonel John Paul Stapp. ( I could be wrong ) He actually decelerated from 632 to 0 mph in 1 1/4 seconds. His body would experience 46.2 times the force of gravity, in essence making him weigh 6,800 pounds for that brief time. For the effects of wind blast, he flew in a jet with no canopy at 570 mph and suffered no injurious.

[Razorfish]

I guess the commentary explains why there's several different sleds.

[sennetor]

I'm no expert in hypersonic fluid flow. But wouldn't the fabric in his outfit impede laminar flow and cause some serious plasma burns?

[deVidsMan]

the japaneese always put these HUGE texts on there, also another video in the corner of a reaction of a person (that's just stupid), all together it makes the japaneese look like jerks.

Sorry but do something professional, don't put yellow and pink huge letters on a video.

[DrMotorDude]

deVidsMan,

Those HUGE letters are for

"Extra Super Nice Asian Video Effectes" - note extra "e" for extra Asian spelling....

[WinterbornSalem]

I honestly dont believe this. I dont know if a man can possibly survive mach 5 let alone mach 9 (thats not a fact, I am basing this on my limited knowledge of the subject matter.)

[redblazerpea]

you can survive at this speed but the problem is the acceleration and sudden stop which can kill. too many g's.

[thatonedude985]

you can "survive" at any speed 1,000 mph ... 10,000 mph ... 1,000,000,000,000 mph. It's the acceleration that causes injury. When you accelerate to any speed usually exceeding 6 to 8 g's causes blackout and very much past 10ish g's can kill you (if sustained for very long). The acceleration due to gravity is one g, therefore at 10'g your body "weighs" 10 times more ... which breaks shit all up in your body. WOOOO!!!

[YFUATIW]

Not exactly true. Atmosphere also has to be negated, or simple air pressure would squash the driver/pilot.

[Zlaja16]

what thatonedude is saying applies in a vacuum...of course there are physical limitations to speed

[sennetor]

Your right- The speed quoted in this video is off by a factor of 10. His top speed was in fact 640Mph which is still quite impressive. Travelling much faster than this would require special areodynamic designs to protect the pilot. Check out Laminar Flow.

[nilsvids]

yes youre right , the speed of 10330 km/h represent aproximatly 3 km/s so itss not possible with a 16 km way... it represent a colossal acceleration... no one can be alive at 10330 km/h on a distance <16km

[HONDA35X]

an Indy car driver survived a 244g crash so of course with pressure suits to keep the blood in ur brain u could ride that speed and survive the gs

[nilsvids]

244g during a fraction of second... if that force is during 1 second you are sure to die...

[sortie9]

Wrong. the top speed is 6,400 (and some change).

It was unmanned since it pulled over 100 gs.

It also ran in a plastic tube filled with helium to reduce the friction. The vids shown here are mostly of the low speed tests of ejections from aircraft. The high speed stuff is to test anti ballistic missile technology.

Google Holliman AFB High Speed test track for more info.

[Sk8Koney]

the correct way to spell genius(plural)

is genii.

thank you tycarp:]

[worldslayer]

fake. the land speed record is under 1000 mph. look it up, geniouses

[domingoscott123]

read the description

it says used to be a world record

[TyCarp07]

this isnt' fake in the slightest. do like you just said and look it up, genius. while you're at it, look up how to spell the plural version of genius.....

[domingoscott123]

lol :P

[FIGHTTHECABLE]

I hate japan!!!!!

[seroyer2]

This was done in the United States. At Holloman Air Force Base

[lithiumdeuteride]

Not as much as Japan hates you.

[Graphpaperowns]

Very cool stuff, but the description is off by one order of magnitude. The Land speed record is 640mph, or 1000km/h, which is still quite impressive!

[Graphpaperowns]

The man is absolutely correct, unmanned rocket sleds DO reach the awesome speeds in the video. The Manned-Sled record is a tenth of the unmanned one. My mistake mate!

[coilgunner2]

that rocket sled was traveling 15 times the speed of light!

XD

...screw you einstein

[weldon0m]

DID I SEE 10,000 KMH ?

[PirateXzibit]

16 km in 2,5 seconds, that's rad.

[TheMidlander]

its john stapp with the sonic wind, it was used to prove that a supersonic ejection could be performed as it has never been done before, the water brakes were used to simulate extreme G force, his highest record was 46.2G's of deceleration and simulated a mach 1.6 ejection at 40,000 feet.

[Wildcard1992]

Yeah but I heard that his eyes burst or something and they took a month to re settle. And his chest got really badly busted up. But he survived.

[drplbiftin]

wtf? they attached a man to that?

[jcg72892]

yea hes a fcking idiot

[stefanoargenys]

yes finally the video that i need !!!!!!FUCKIN AMAMZING XXXXX

[TheOnc3ler]

This needs to become an Olympic event!!!

[JDHauser]

LOL with x60 G they wont live for long after each event..

[lujack82]

dumbass

thats all i have to say

[eljaco88]

it isnt the land speed record, cos its on rails, not wheels, and that is never 6000+ mph

[juggaloexmortum]

it's not on water and definitely not in the air. so tell me genius, what type of record it was?

[eljaco88]

i never said anything about water, maybe it is i dont know

[juggaloexmortum]

you've answered for me

[specnopip]

nice camera that records all 16km :S ^^

[kirkmach32]

Philipc1690,

Genius. Quick, run to Stanford, they have been searching for answers. They can really use an intellect like yours.

[ViolentVendetta]

i bet thats a damn awesome feeling

[madnesscombat5]

Not really. Once he hit the water, he stopped so fast he had a 'red-out' Where all the blood in his eyes, and some in his face rushed to the surface. Hed be blind for a couple days, and his eyes would look pure red.

[PunKilla91]

Can't they just send it without a human ? XD

[fruitbooting132]

wheres the fun in that?

[madzach21]

lol that was back in the old days when they would put a person in it. hint... before they reached mach 9. today's cart that runs on it (reaching mach 9) cannot be ridden by anyone because the g-force would kill you. it would be equivalent to multiplying your body weight by 150.

[philipc1690]

could they not put a really skinny person on it then ???

[zuss10r]

No. They tried Amy Winehouse, but she sparked up the solid rocket fuel booster and smoked the lot while waiting to do her run:)

[IC2720]

dude, that is too funny. LOL

[sumthingsick1]

look up john stapp on wikipedia a human can withstand 45gs in the forward position with proper harness

[Diabolikal23]

Colonel John Paul Stapp

[philritter21]

Runs with humans = never going more than the speed of sound

Runs without humans = upto mach 9.74

This video doesnt exactly make that clear.

[homeslice2387]

nice find, its important to note that the land speed record on rails is Mach 8.47 and not 9.74....

[Darushiokan]

I want that in the next disney land park :D

[murfrules107]

go to google and type in rocket sled land speed record and click on the third thing that comes up

[r0ck3tsm0k3]

Rocket sleds are great - we need more videos!

[supercookies]

if he were going 10330 kmh he would pull 155 g's or he would weigh 30000 pounds

[r0ck3tsm0k3]

You jerks are messing up so many different things. No person ever went nearly that fast on earth, or on a rocket sled. But unmanned sleds did go this fast. The G-force experiments were all below the speed of sound, and hut on the order of 80Gs.

[Retsam19]

He wouldn't be pulling any g's at the maximum speed because there would be zero acceleration at that point.

[ericcox2]

That's Col. John Stapp (sp?) Yeah he was "jacked up" - he went through 40 Gs of acceleration and was temporarily blinded, but he lived and completely recovered. After this test, the army halted human testing of acceleration effects.

[omairgeforce]

ericcox2 , can u tell me how much geforce a common human being survive??

[ericcox2]

No.

[rohleks]

alot over 20

[rr111160]

auto racers have been measured hitting walls at aroung 200g, but it's only for a small fraction of a second.they routinely survive.

[mycroft999]

want a go

[nspinicelli]

I heard about this experiment. The acceleration was incredible, but what was insane was the deceleration rate. His eyes partially filled with blood, his organs shifted, he was pretty jacked up.  Correct me if I'm wrong...

[colbertpresident08]

word

[shittyfuck]

the man will die...

[landshark004]

The land speed record was set at the rocket sled track in New Mexico. They went so fast they had to surround the track with a plastic tube of helium to reduce air drag.... darn fast! This was for ballistic missile interceptor tests, not pilot ejection studies as seen in this video.

[landshark004]

It was the sled track at Holloman AFB, not the Sandia sled track in Albuquerque.

[ZClipze]

wiley coyote can do it without a helmet

[mrdog44bc]

They should make planes out of coyotes, then they'd survive crashes. I'd recommend a helmet.., mine's always highly polished due to all the friction

[zzzepptri]

Damn good point

[mrdog44bc]

this is fake. the fastest land speed is by the marlin, at 72miles per hour, which is mack 150, and that equates to a g string of 200

[supermagicmilk]

no, it's real. i've been out to this test track before and seen a test run. it really is that fast. (i live about 45 minutes away from the track)

[mrdog44bc]

Guh?...Buh..

[Intranetusa]

actually the fastest UNmanned land vehicle (this one) is at mach 8.5

[transhuman7]

More speed!!

[sleepingeye]

that driver must be insane - and he doesn't look very good after the ride

[danwill99]

His name was John Stapp , the acceleration was somewhere around 20 g , and the water brake stop subjected him to 40 g's!

If I remember correctly , he was temporarily blinded , and had bruises all over his body from the blood vessels rupturing , another couple of seconds would have killed him.

the helmet broke during the stop

[scrapist1]

wat the hell u need a driver if he just sits ther hoping nothin goes wrong

[komokaziboschetti]

id like to ride in soemthing that goes 6000 mph lol

[Intranetusa]

you'd die dude

[lookn4thepowpow]

Shuttle reentry is Mach 25 that might be more than 6000 mph

[lookn4thepowpow]

To test human endurance

[dragonfyir]

there no way he could have survived that speed exposed. the heat from the air friction would have burned him alive

[yfzrider13]

thats what i was thinking.. i think he has some type of suit, but still.

[danwill99]

it was between 600 and 650 mph ,the air friction won't "burn you up" at that speed , rip your face off , maybe.

for the rest, read my reply to sleepingeye.

I remember seeing a video of his face during that test , it didn't look like fun.

[iwanabana]

screw thrust SSC

[k0nformity]

that was shot at the holloman air base the test track is 15.4 kilometers or 9.56 miles the track is capable of withstanding 10,000 feet per second or mach 9. the fastest pass was actual 10 430 km/h.... its all contained on the wiki site below...

h t t p://en.wikipedia. org/wiki /Holloman_Air_Force_Base

[Postie1]

These wern't all from the same test runs. Some were recent with an F-16 cockpit, some were from the 50's and 60's.

[Drumm3rDud3]

If such is the case that this all happened in 1954, besides the fact that colour film was rather hard to come by back then, it is somewhat unrealistic considering that the nosecone/cockpit is taken off an F-16 fighter (or some other similar jet) which won't even be on the drawing boards for another 30 yrs

[mrshl9898]

check out HHSTT 6,453 mph land speed record, 300 or so mph faster.

[zabuzadarkness]

well he must have broke the sound barrier, did anyone see a sonic boom?

[IronWarrior07]

Humans can survive those speeds, look at the spaceshuttle.

[footiemad87]

yeah, when they are inside
