Boom roasted

chuck norse cigar lighter

[chunkstyle5]

@George19881988 You mean Atlas V, not Saturn V.

[eb62224]

thats a big candle!! lol

[Trying2show]

Boy if someone happened to be walking back there. Toast! Lmao

[George19881988]

This type of rocket booster provides about 860,000 LBF (pounds of thrust) and five of these are used to take the Saturn V rocket in to space. Amazingly, each one of these rockets only provides about 25-30% of the thrust provided by the Space Shuttle solid rocket boosters, which provide approximately 3,000,000 LBF at maximum! Equally amazing, the smaller engines on the Shuttle provide approximately 510,000 LBF at maximum, which is around 60% of the power of this booster alone.

[ugowar]

@George19881988 What do you mean the Saturn V rocket?

[George19881988]

@ugowar Woops, my mistake. I meant to say Atlas, not Saturn. I should have said "and five of these can be used to take the Atlas V rocket in to to space", but you've already written that in the description.

[triathlon4ever]

@ugowar no atlas v its a different one. Saturn V was part of the apollo missions in the 1960s and 1970s

[countryfarmer1969]

@ugowar Saturn V rockets were used on the Apollo missions

[eb62224]

@ugowar the most powerfull rocket ever made, i think....

[zombieX111222333]

@George19881988 these are used on the atlas 5 and i think the space shuttle

[zombieX111222333]

dude that thing slides forward when it frires geez NASA be careful with that shit

[ugowar]

@zombieX111222333 This is not NASA.

[zombieX111222333]

@ugowar THAT explains it

[triathlon4ever]

@zombieX111222333 its a private company with contracts with nasa

[strongman17]

Damn thing will cook a steak in 1 second flat...it's final, is time for a bar-b-q

[Hautamekki]

need such a thing for my cigarettes in the garden

[ti994apc]

If they want to waist the perfect reliability reputation of the Atlas V, go ahead and strap on a solid rocket booster. One only needs to look at the Delta II and Challenger explosions to see where it will land them. If more power is what you want, make a bigger rocket with another RD180 engine.

[OctopuPilot]

What keeps the SRB on the ground and prevents it to take off?

With all this thrust you'd need to anchor it to ground with something real strong.

Does somebody know how it's attached to the ground?

[rss0246]

Five (5) of these were attached to an Atlas V rocket in January of 2006 to propel the "New Horizons" space probe towards Pluto at 39,000 mph. Will take the craft just under ten years to get there...

[ugowar]

@rss0246 And even that is with a Jupiter gravity assist along the way to cut down on the travel time. Without it, it was supposed to be something like a 12 year trip.

[rss0246]

@ugowar Yup. New Horizons is going about 52,000 mph now!

Note: Last night here another Atlas V took off from the same pad (Complex 41) carrying a new and secret Air Force test vehicle into orbit for nine months. The OTV has stumpy wings, uses re-entry tiles and though unmanned, looks very much like a shuttle orbiter (but only 1/4 the size). Interestingly, this Atlas used NO SRBs at all. Not surprisingly, the take-off and ascent into space seemed slow and arduous...

[ugowar]

@rss0246 Yep, the Atlas V 5m fairing versions look totally badass, with or without the solids. Last night's launch was visually also quite nice, was the first time I saw the venting from the Centaur LH2 vent actually be visible from the ground - check it out at after T+2 min 40s. You just can't beat early evening/morning launches for visual clarity with the darker sky, but illuminated rocket at altitude.

[Gruntol5]

A far cry from my weedkiller (sodium chlorate) and sugar rockets of the 1950's. I packed a large grease gun with my mixture on one occasion. The nozzle was too small for the burning rate and it exploded violently after about 10 seconds. My sister, riding a horse about half mile away, claimed a thrush fell out of the sky, dead. It might have died of old age, but I always wondered. Shrapnel perhaps. The man next door yelled out "you boys need your fucking brains tested!" Ah - happy days.

[ugowar]

LOL! Boys will be boys, I did similar sorts of stuff myself, only with less "advanced" stuff - just regular black powder.

[Membrane556]

I did something similar but with sugar and KNO3.

I first tried black powder but that was unreliable.

[Stall0wnized]

wow, they burned the amount of fuel that my car would need in a lifetime in <2 minutes....

[TheYouwillsuffer]

at first i thought that thing was going to take off, that was cool.

[nextone7]

i badly need this one for my smart ^^

[davefox72]

This is just too much Thrust for your average commuter....The inability to shut off the thrust after ignition could result in serious traffic snarls, accidents, even death. This type of research is expensive, pointless, and if implemented far too dangerous for the average commuter!

[Sereniance]

Wow... that´s a rush.

[jmar1371]

If these morons want to believe they can hear the sound of a fly over this motor, let 'em. They've obviously never been anywhere near a rocket motor much larger than an Estes D12.

Isn't U-Tube great? The vids get 'em here, but the real entertainment is in the remarks below the vids. It's amazing...

[CriticalBanana]

I'm just as amazed that the microphone still picks up the fly that comes in from the bottom of the screen at 0.30!!!

[ugowar]

That's not the fly it's picking up, that's the announcer's voice drowned out in the noise. Listen further and you'll hear him talking.

[CriticalBanana]

Hmm maybe. Listening through headphones nothing, but I was listening on pro audio equipment before, and on checking, I'm 60/50 that the fly is audible.

I've concluded that this camera is a lot further away and zooming in which would explain it. Anyway... lol

[ugowar]

If it was a lot further away, it wouldn't hear the sound of ignition instantaneously but with a sound propagation delay. It's not a fly and cannot possibly be given the amount of decibels this motor puts out.

[CriticalBanana]

Except that this isn't footage from one single camera/mic unit.

It's a composite made from multiple sources.

I still maintain that this particular cameras mic picked up the fly and it's A/V recording was mixed with other inputs including mics. Even the guys mic.

[ugowar]

Look, a rocket motor firing is the loudest man-made sound this side of a nuclear explosion. It puts out so many decibels there's no freaking chance a *fly* would be heard. Also, this camera is close in next to the test site not far away zooming in as the perspective is all wrong. Even if it was far out, that would produce a double sound - one from your alleged close-in mic and one that captured the "fly" sound. There is no such sound, in fact only two sounds - the booster and the announcer.

[ugowar]

The sound at 0:30 is the same as 0:41 which is the faint sound of the announcer saying something inaudible. I don't think you realize the amount of noise this thing produces - it literally visibly kicks up dust at the surrounding hills when it's ignited as the ignition acoustic wave propagates.

[fuji2failo]

no-wounder today was kind of cloudy

[demonator65]

wow imagine standing in front of that strapped to the grount with titainium chains and shackles that are anchored 200 feet under ground...dude that shit would turn your damn bones into cinders...

then it would turn your cinders into cinders then blow you away with the dust...lol

[markuks]

"Honey, the marshmallows looks kinda done now"

[tyn1963]

Hopefully, this will prove very useful for the future of NASA and the Aeronautics industry. Very impressive power, very impressive display. 2 million horsepower!

[AwsomeAthiest]

Actually the solid rocket boosters produce around 22 million hp each, the rocket engine on the space shuttle develops 12.5 million hp alone!

[kooldog98]

imagine if the restraints failed and the rocket went wild like a unmanned garden hose

[24preacherboy]

When I was a kid, we used to take bottle rockets off their sticks and light them. We called them nigger chasers.

[demonator65]

-.-

[Ferrariman601]

I wanna strap this to my 2002 Hyundai Accent! lol

[perrystroika]

its how they fry KFC. (The 11 secret herbs and spices are added later)

[planedrawer]

Hey dude, you got a light!

[Starwing1272]

Light nothing.... Who's got the Marshmellows and Hot Dogs????

[mikey012345]

To be honnest, if its pumping out that much thrust, wonder whats holding it in place

[ugowar]

If you can build something that's pushing forward so hard, chances are you're also able to build something that holds it up even more.

[UkWide774]

nicely explained,, i hope it does not disturb you? i just like you answer :P

[chorioretinitis]

In fact even the strongest rocket motors and engines give out only thousands of tons of pressure at best. Piece of cake to hold that down with a few days of welding and bolting.

IF it got loose, well, then it would do 0 to 60 in one second.

[maglight117]

more like 0.01 seconds

[Individuality1990]

54mm solid rocket engine, propellant r-candy (KNO3 and Sucrose) went from 0-mach 1 in 3 seconds, this one been so bulky and large, would take at least 30 seconds

[kevmulder]

30 seconds for this to hit 60 MPH? Are you seriously offering this as a valid estimate?

[Individuality1990]

...where did you get 60mph from?

I should have made it clearer, i was referring to Mach 1.

[r0ckt3hc4sb4h]

It probably has its nose against a load cell.

[CaryChleborad]

The rocket is being fired in what is known as P3 test stand. You can't see it but outside of the left side of the field of view is a 3 million pound block of concrete that it is pushing against. You also don't see the post fire of how it melts the concrete in the back of the stand.

[Nuketime201]

Holy crap thats cool, I understand they need to test them...but seems like such a huge waste of fuel :D

[detibry]

its all in the budget.

[hbme2103]

how many horsepower does one of those engine produced. i'm sure it's a lot.

[ugowar]

Rocket boosters are not measured in horsepower, but thrust and specific impulse (something mildy analogous to miles-per-gallon in rocketry).

This one generates an average of 1,270 kilonewtons or 420 tons of thrust (933,000 pounds for you American types).

[hbme2103]

that's a lot of thrust. really.

[r0ckt3hc4sb4h]

Solid rocket boosters can be rated in horsepower, although it is usually not the de facto unit for measuring their performance.

[DeerJumper101]

i went there at 12/04/2008 it was awesome!!!! i love it all i know is its not really loud and does not hurt ur heart when u feel it vibration thats all i know and i was on TV!!!!

[ugowar]

If it was on December 4th, you witnessed a Space Shuttle Solid Rocket Booster test, a much larger booster than this one.

[Parubhi]

Do you end up with silica on the ground after a test run?

[deviceone]

I'm sure there had to be plenty. God I bet that place smelled horrible.

[punishedexistence]

Look closely at the ground where the flame was, it looks like it's popping. That's pretty cool.

[000darkstar000]

Holy Crap!thats Awsum!thnx 4 this vid.

[thaopa]

what have we learn from this test??.... that fire is hot.

[ugowar]

Actually, we have learned something a bit more important: the booster works and it does NOT blow up.

Most normal people learn fire is hot while they're still babies, mr. smart guy.

[Parubhi]

Thaopa,

Don't you have some tree's to hug?

[iurikorolev]

Good video ugowar !!!

Do you have TridentD5 Solid Rocket Booster Test video ?

Thanks

Iuri

[ugowar]

Nope, sorry.

[lolle18]

What is this baffle for, which can be seen moving from right to left at the of the firing?

[ugowar]

They mention something about a CO2 quench, I think it's actually a pipe feeding CO2 inside the casing to extinguish the residual flames.

[SwornEnemy183]

what the f ...

[sir62092]

bloody hellfire!

[ckatz71]

Hey is this at the sacramento plant? My dad worked on the line 5 division back in the day.

[stuartthegrant]

Wouldent want to be the man in the Bunker!!!

[thors6]

My dad designed this with a team of other engineers at AeroJet. and the stuff they use to strap this down are 3 foot long chainlinks and bolts that are 2 feet long.

[chorioretinitis]

Imagine what kinda hardware they need to strap this thing to the ground. Or what would happen if it got loose.

[yotube123454321]

lol, accidentally unscrew a few bolts

[GeorgeJansen]

That's Hot!

[vuurwerktomw]

I really dont ever wanna stand behind that thing when its acitve....

[ugowar]

These are bad enough, but Space Shuttle SRBs are EVIL with respect to firepower.

[loki4145]

sorry

[loki4145]

Russian engines RD-180

[ugowar]

This is not the RD-180 engine. This is the strap-on solid booster used on heavier Atlas V variants.

[FiveCentsPlease]

Heh...that controller sounds just like the countdown to destruction announcer from the Austin Powers movie.

Five minutes and cooounntinggggg!

[DoYouFeelTheTrance]

Thats powerfull
