@masoaviator....they're spray nozzles with water pumped through them...when they're off during the test, the tremendous low pressure caused by the velocity of the rocket exhaust "sucks" water out of them, so there's always a little water coming from them...but when the nozzles are activated, a huge amount of water is being sprayed...fyi....it's not to cool, it's to dampen the sound waves so they don't demolish the test stand...usually opened and closed as the rocket throttles up and down....
Sometimes I see things like this and it makes me sad that we may never be able to do anything like this again. I am very disappointed in my generation (Gen X). While some of us have done well and made individual contributions we will be remembered mostly for things like Facebook.
@Anakin44441 It's a shame but I think you are spot-on correct. Now it's all about social networking, becoming the next "IT' on American idol or something else completely mind numbing. If this does happen again then it will be coming out of China not here in the US. Our time is past and the greatness we once new is a thing of the past. The Roman Empire, the British Empire, the Ottoman Empire all ashes..now we are repeating their history and doing it to ourselves.
Not to be anal but the S-1c/ F-1's were fueled by a refined Kerosene with Liquid Oxygen as its Oxidizer. Not Liquid Hydrogen fuel. The second and third stage J-2 engines were Liquid Hydrogen/ Liquid Oxygen fueled.
@TooMuchGass The motor is cooled by the cryogenic propellant being circulated around it in cooling channels prior to being burned. Not only does this keep the motor cool, it preheats the propellant for more efficient burning in the rocket motor.
We care about Harley Davidson as we post their stickers about "buying American" in the back window of our trucks never really taking the time to notice that the sticker was made in China.
We were such an amazing country once. We just simply were. But we are now Walmart. We are Mcdonald's and Target. We are "Designed by Apple in California, Made in China". We are "a day without a Mexican" and it scares us. We are fat. We are lazy. We vote Democratic or Republican and we know it really won't matter because nothing will get accomplished. We are a country that cares about Directv on a 60 inch class LED tv made in China.
Can any one tell me why it appears the surrounding (ambient) air is only 'lazily' being drawn into and around the 'bells' that are discharging huge amounts of combustion gases? I was expecting to see a virtual torrent of slip-stream effect (Bernoulli?), or Coanda effect as the surrounding 'atmosphere' (displaced by the thrust volume) would be 'pushed' into the vacuous areas surrounding each 'bell'?
Isn't there a huge pressure drop just behind each thrusters bell mouth orifice? mrc109
I would be willing to bet that the dozen or so uniformly sized bits of white debris being sucked in from 4:30 to 4:50 are styrofoam coffee cups. I think I saw a sheet or two of newspaper, too.
Sputnik scared the crap out of Americans. There was real evidence that the Soviets could put a nukes in orbit and drop them on us at will. Kennedy focused on the man on the moon by 1970 as a more-or-less-peaceful goal to put us in the lead. Then Kennedy was assassinated and, as the goal of a martyr, there was nothing going to stop us from getting to the moon. It was an exhilarating time.
With the shuttle now retiring, seeing this this makes me really sad - this country is so backwards in priorities right now.
I saw this test stand when I worked for Rocketdyne (makers of the Saturn and Shuttle engines)....the sheer size of the stand alone is simply awe-inspiring
just curious, does any other American here feel a little ashamed that it was a nazi building our rockets? Don't get me wrong, i think Von Braun did an amazing job.
@dragonforce2387 Von Braun only did a small portion of the work on the Saturn. It was in overwhelming percentage an American rocket, made possible only thanks to American industrial technology (no country in the world had, or has to this day, the ability to produce engine bells as large as in the F-1)
Instead of wasting money on stupid wars, we should be investing in education and R&D, the stuff we need as a society to move on. The only ones advancing are the rich and the greedy corps.
I broke the suspension of a RCF 12" woofer playing a shuttle launch here on YT, i swear. 50euros for fix it but the temptation to listen it loud... was too high. ^^
Usually i use headphones for youtube or gaming, but this kind of stuff need to be played on loudspeakers, it's too funny to see you neighbors, parents, pets.. going ballistic rofl.
What a few hundred aerospace engineers built in the 1950's using protractors and slide rules a few thousand aerospace engineers at ATK, Aerojet and PWR with SolidWorks and CFD cannot. We need another huge kerolox engine.
I have stood next to the F1 engine at the KSC in Florida and i am dwarfed by the size of it.to have seen/heard this engine in action must have been something special. Probably the most powerful rocket engine built to date,simply awesome.
This is by far the most impressive piece of hardware built to date. I followed the race to the moon as a teenager and it was such an exciting time. I've had the opportunity to see 2 Space Shuttle launches but I'm sure they are nothing compared to a Saturn vehicle launch. I wish I could have witnessed one live. Thanks so much for posting...
@northernhoser Falcon 9 Heavy is on the way. Biggest launch vehicle ever built since the Saturn V. I think the date set for it was 2012 or so. Look it up, I could be wrong.
Once i have seen this one, i just have to see it now and then, especially hear it!
I really like the sound of the fuelpumps revving up (or so) like, 55000HP for the fuelpumps alone... and they make this 'spooky' sound right before the man-made thunder... Absolutely love it!
I was under the impression the noise these things made was deafening from many miles away. This footage frankly makes them seem rather tame and less violent than they really were...
@beeroosterm Derp Derp you are looking at a YT vid, not sure how that is supposed to transfer to real life. Not even sure what the poor microphones were able to capture at 200+ db.
I saw one SSME (space shuttle main engine) tested at Stennis years ago. I was about 1/2 mile away and the sound was impressive (it was fun to watch my jeans fluttering in the pressure waves). I can only dream about how amazing it would have been to see an F-1 test.
Ah those were the days, when cars were made of steel and chrome, women stayed home and cooked, there were no illegal aliens, and nobody had ever heard of Al-Queda.
If you look closely at the leftmost engine in the closeup clip at about 2:25, you can see the engine swivel back and forth while a gimbal test profile is run. The outer four engines on the Saturn V first stage could be swiveled to steer the rocket. You can see all four engines being swivelled at about 7:15 in the last clip.
Gulping 20 metric tons of fuel a second, you could get a idea of the power of those engines and the enormous and complex system that managed those incredible loads of thrust, and power to weight ratios-we need a visionary at NASA to take all of us to the glory of space again, and the final frontier.
@BaseStationZero What do you mean? You're speaking a foreign language. ....for us Earthlings please? Turbines? Doesn't the rocket fuel get sucked out naturally by a venturi effect? This is 45 year old technology.....why haven't we been using it to launch heavy lift all this time?
@JetMechMA See Wikipedia's articles on "rocket engines" or f-1 engine. Most (but not all) high-performance liquid fueled rockets use high pressure pumps driven by a turbine to provide propellants under very high pressure to the combustion chamber for high efficiency. The turbine is typically driven by a high temperature "gas generator" attached to the engine that burns a relatively small amount of the propellant to drive the turbine.
@BaseStationZero The top half of the F-1 engine nozzle was actually cooled by circulating fuel through the engine bell before sending it to the injectors to be burned. The bottom half of the nozzle (the "nozzle extension") was "cooled" by injecting fuel-rich exhaust gas from the gas generator (that drives the pump turbine) into the lower half of the nozzle so that it flowed out along the inner wall. (I think this may account for the brown color of the exhaust as it exits, but I'm not sure.)
I have huge respect for people back in those times, for making the dreams into reality. I miss this mentality today, and notice than money is more important than achievement.
@avssagar It's pretty rusty. Last test program in that position was the Delta 4. Current plan is to re-activate for the Ares upper stage, if there is such a thing.
Yet another reminder of what can be done given mountains of cash and a martyred President. Apollo was indeed an example of "the right place at the right time." *sigh* Never to be repeated or seen again. Alas! As Apollo was my religion as a child.
Awesome footage just goes to show what achievements are possible when there is a will. Too bad politicians today are only interested in spending countless billions on bailing out greedy corporations and stirring up Middle East wasp nest.
Jesus christ, how did they keep the test stand from coming apart? Amazing thinking about the engineering that went into the testing alone of the Saturn launch vehicle.
Another cool moment in this video that some won't notice is at 1:35 if you look at the top of the propellant tank you can see the vent valve open when the engines shut down. The LOX doesn't want to stay a liquid, it wants to boil off. The valve is open and close just before engine start. Then, when the engines shut down they open the vent again due to boiloff. They must have blown up a lot of stuff to get all this working together, amazing! Thank you for posting this video CEVOrion
incredible! but what's with the stuff being sprayed onto the engines at 8:40? also it sounds dofferent than i thought, more of a crackle (sort of like a bonfire) than the roar i expected, does perhaps it would have been louder and sounded different in person, or the camera just couldn't take the noise!
The stuff being sprayed is water to help suppress the pressure waves from reflecting off everything and destroying something. Like rolling a window down at 60mph, in the vicinity of the engines the pressure has pulled down because of the exhaust sucking everything down and out the test stand. When it stops that pressure equilizes quickly. Start and stop the engines is the most hair raising moments.
Those actuators that are being swung around at the top of the engines, they are basically steering the rocket, right? If that Is so, I always wondered how the saturn V remained upright at the beginning of the launch as the fins at the bottom would serve no purpose until there was a fair amount of air flowing over them.....
Yes they ran on refined kerosene. But even more impressive was that all of the valve and engine actuators also were powered by the high pressure kerosene. So they did not have to carry a hydraulic system, they drew off the high pressure fuel supply from the turbopumps to supply hydraulic pressure to the actuator pistons. So you see the engines being swung around by the actuators at the top of the engines, those and the valves were also working off the fuel. Very clever!!!
some of what you are seeing is due to the initial flashing of liquid oxygen into a gas as it hits the warmer surfaces downstream of the main valves but ignition has not yet ocurred. But yes, it is a mix of unburnt fuel and Ox.
all these engines at full power produced about 160 million HP...I wonder how in the hell did the support structure of the building stay intact under the load of such tremendous power!?
I have tried twice already to respond to this. It keeps bouncing me out. The test stand is at NASA's Marshall Space Flight Center in Huntsville, AL. It was built in the early 1960's to accommodate a launch vehicle with a thrust of up to 14,000,000 pounds of thrust. Lab Director was Karl Heimburg and his deputy was Bernhard Tessmann. Tessmann gave me this information originally.
Just play this through a high quality set of full range speakers and subs. Man....the sound energy will reverberate through your body even at medium volume.
yeah I have never seen anything like that before, by the way thank you so much for this video, specifically for leaving it raw without annoying music or title cards
The J-2X is a derivative of the J-2, which was on the second and third stages of the Saturn V. This video is of the 1st stage of the Saturn V, which was x5 F-1 engines. Each engine was ~1.5 Mlb of thrust and was Lox/RP-1 (Kerosene). J-2 and J-2X are Lox/Liquid hydrogen.
The Saturn first stage used what was called an engine 'cluster'. This was a video of a full "5 F-1 cluster" test, a combined total of about 1.3 million lbs. thrust. About '69 or '70, before my time, they tested this arrangement on a day with a low ceiling (clouds) and blew out windows 30 miles away and registered on the Mobile, AL Richter scale at 3.5, about 100 miles to the east. Nowadays, you barely notice they test, it sounds like a distant steady thunder.
The S-1C is a complete rocket stage. The F-1 is the actual engine being used in this video. The Ares series will use a J-2x, a derivative of the J-2 engines used on the S-IV-B stage of the Saturn V.
Yes, but alas, our wonderful Kenyan President just killed the ARIES program, and for all practical purposes, the American space program.
750 Billion for stimulus package, 300 Billion to keep Government Motors running, 1.2 TRILLION for health care "reform", yet the village idiot in the white house kills the measley 5 billion ARIES program.
Tragic loss for the American space program. We will never catch back up in the race for space.
180 million horsepower and developed by German rocket ace Werner Von Braun. Currently there is no rocket available that is powerful enough to get to the moon. Unless of course they pull these Saturn V's out of all the museums!
Although I'm no rocket engineer, I do have an explanation for the pops and bangs in the audio: supersonic exhaust velocity. The shuttle's SRBs make a similar sound, and you also hear it in recorded footage of Apollo launches.
If there's a rocket engineer out there paying attention to this, what are those "pops" and "bangs" that I'm hearing. Is it the acoustics or the limitation of audio of the day?
Thats the sound of about 7.2 million pounds of thrust beating the air into submission and those are the sonic shock waves making the crackling sound you hear!
its actually the combustion of the engines...from 4 miles away the acoustic energy can disasemble a building -there are a few videos on Youtube called "Apollo 4", one of them has bits of Walter Cronkite commentary, the sound takes around 12 seconds to reach the press (3-4 miles away) , before that all is completely quiet (unlike the way a launch is shown on tv), the sound usually hits right as they announce "Tower clear", its at that point where poor Walter is stunned into shocked silence.
I'm no engineer but, if you listen to the audio it's the same from every segment of the film. I would be willing to bet that this film had no audio originally and it was added to it.
I'd like to jump in there.

@avssagar It's pretty rusty. Last test program in that position was the Delta 4. Current plan is to re-activate for the Ares upper stage, if there is such a thing.

Yet another reminder of what can be done given mountains of cash and a martyred President. Apollo was indeed an example of "the right place at the right time." *sigh* Never to be repeated or seen again. Alas! As Apollo was my religion as a child.

Hey kids, I've caught brief glimpses of what looks like a cluster
of five F-1 engines strapped to a test stand minus the actual S-1C
stage on NASA TV occasionally and IIRC it's in Black & white, No sound.
It's a short clip but they're gimbaling the engines all over the place
and it looks weird. I'd love to see the whole clip if anyone has it.

Eh, The white stuff coming out of the engines at start up
is VERY Large amounts of liquid oxygen rapidly boiling
back to the gaseous state. Mix this with LARGE amounts
of RP-1 and YES Virginia, You can in fact go to the Moon!
These engines are just neater than shit on a stick.
I DO think they're good!

Jesus christ, how did they keep the test stand from coming apart? Amazing thinking about the engineering that went into the testing alone of the Saturn launch vehicle.

Another cool moment in this video that some won't notice is at 1:35 if you look at the top of the propellant tank you can see the vent valve open when the engines shut down. The LOX doesn't want to stay a liquid, it wants to boil off. The valve is open and close just before engine start. Then, when the engines shut down they open the vent again due to boiloff. They must have blown up a lot of stuff to get all this working together, amazing! Thank you for posting this video CEVOrion

incredible! but what's with the stuff being sprayed onto the engines at 8:40? also it sounds dofferent than i thought, more of a crackle (sort of like a bonfire) than the roar i expected, does perhaps it would have been louder and sounded different in person, or the camera just couldn't take the noise!
yop911 1 year ago
The stuff being sprayed is water to help suppress the pressure waves from reflecting off everything and destroying something. Like rolling a window down at 60mph, in the vicinity of the engines the pressure has pulled down because of the exhaust sucking everything down and out the test stand. When it stops that pressure equilizes quickly. Start and stop the engines is the most hair raising moments.

So minnie4mouse,
Those actuators that are being swung around at the top of the engines, they are basically steering the rocket, right? If that Is so, I always wondered how the saturn V remained upright at the beginning of the launch as the fins at the bottom would serve no purpose until there was a fair amount of air flowing over them.....

Yes they ran on refined kerosene. But even more impressive was that all of the valve and engine actuators also were powered by the high pressure kerosene. So they did not have to carry a hydraulic system, they drew off the high pressure fuel supply from the turbopumps to supply hydraulic pressure to the actuator pistons. So you see the engines being swung around by the actuators at the top of the engines, those and the valves were also working off the fuel. Very clever!!!

They ran on heating oil (refined). The greatest engines built by mankind.

The way the shock waves and sonic winds break up its own cloud from :53 through :60 showcases some of this stages incredible power.
MightySaturn5 2 years ago
some of what you are seeing is due to the initial flashing of liquid oxygen into a gas as it hits the warmer surfaces downstream of the main valves but ignition has not yet ocurred. But yes, it is a mix of unburnt fuel and Ox.

Does the fuel fall through the exhaust (unburnt) for a second or two before ignition anyone?

I have tried twice already to respond to this. It keeps bouncing me out. The test stand is at NASA's Marshall Space Flight Center in Huntsville, AL. It was built in the early 1960's to accommodate a launch vehicle with a thrust of up to 14,000,000 pounds of thrust. Lab Director was Karl Heimburg and his deputy was Bernhard Tessmann. Tessmann gave me this information originally.

The new J-2X will only use a cluster of two of these derivatives, still nearly 700k lbs thrust.
EphemeralGenius 2 years ago
@EphemeralGenius
The J-2X is a derivative of the J-2, which was on the second and third stages of the Saturn V. This video is of the 1st stage of the Saturn V, which was x5 F-1 engines. Each engine was ~1.5 Mlb of thrust and was Lox/RP-1 (Kerosene). J-2 and J-2X are Lox/Liquid hydrogen.
Faju4u 2 years ago
The Saturn first stage used what was called an engine 'cluster'. This was a video of a full "5 F-1 cluster" test, a combined total of about 1.3 million lbs. thrust. About '69 or '70, before my time, they tested this arrangement on a day with a low ceiling (clouds) and blew out windows 30 miles away and registered on the Mobile, AL Richter scale at 3.5, about 100 miles to the east. Nowadays, you barely notice they test, it sounds like a distant steady thunder.

The S-1C is a complete rocket stage. The F-1 is the actual engine being used in this video. The Ares series will use a J-2x, a derivative of the J-2 engines used on the S-IV-B stage of the Saturn V.

Yes, but alas, our wonderful Kenyan President just killed the ARIES program, and for all practical purposes, the American space program.
750 Billion for stimulus package, 300 Billion to keep Government Motors running, 1.2 TRILLION for health care "reform", yet the village idiot in the white house kills the measley 5 billion ARIES program.
Tragic loss for the American space program. We will never catch back up in the race for space.

Although I'm no rocket engineer, I do have an explanation for the pops and bangs in the audio: supersonic exhaust velocity. The shuttle's SRBs make a similar sound, and you also hear it in recorded footage of Apollo launches.
dragon4166 2 years ago
If there's a rocket engineer out there paying attention to this, what are those "pops" and "bangs" that I'm hearing. Is it the acoustics or the limitation of audio of the day?
6x10x23 2 years ago
Thats the sound of about 7.2 million pounds of thrust beating the air into submission and those are the sonic shock waves making the crackling sound you hear!
sakoshooter48 2 years ago
its actually the combustion of the engines...from 4 miles away the acoustic energy can disasemble a building -there are a few videos on Youtube called "Apollo 4", one of them has bits of Walter Cronkite commentary, the sound takes around 12 seconds to reach the press (3-4 miles away) , before that all is completely quiet (unlike the way a launch is shown on tv), the sound usually hits right as they announce "Tower clear", its at that point where poor Walter is stunned into shocked silence.
MightySaturn5 2 years ago
Go to a shuttle launch. Same pops and booms.
It's just the sound of the engine reverbrating off of the ground, clouds and any and all objects in the area.
Think about a thunderclap that never stops.
