I am one of the only two gals who worked as System Test Engineers on the first stages (S-IC) of the Saturn V out of 400,000 people in the 1960s. Our stages worked perfectly!!
Sara Howard Respect Mam "Salute". The Rocketdyne F1 engine is still the most powerful engine till date. I wish I had a chance to work with something like it. I am a Software engineer but by true passion is to design a rocket engine like this. I am have a plan and I hope I will be successful in it.
+Sara Howard Thank you for all your work and contributions to the success of the the Apollo missions. I am in love with the F1 engines, they are not only marvelous machines but breathtaking, and being able to listen to them crackle and thrum like this... I can't imagine more beautiful music. The Saturn V was just a gorgeous launch vehicle, I wish I could have seen a launch, oh my heart aches thinking about it! I am curious you can hear a harmonic just as the engines start, is that the turbopump? Anything you can tell us about that Sara? Much appreciated. =)
Thank you, Holly. The noise generated by the F-1 s is too loud to determine what the cause was. I have lots of video of static tests and launches. Your guess is as good as mine. Smile.
I never get enough of that Banshee scream at 8:44 and 9:23 (after the siren) which are the turbo pumps spinning up. Raw power. The pinnacle of engineering. And ALL F1 engines used in the Apollo programme worked without a failure. Eat this SpaceX!
If I had the choice between a Saturn V (built by the engineers in 60s) and Spaceship, I would not hesitate and get into the Saturn. I don't trust modern engineering and the price/quality cuts they're making 😜
No reason to crap on SpaceX. NASA has fallen so far from the Apollo days that I no longer consider the current incarnation to be the rightful holder of the crown (to turn a metaphor). SpaceX would be a fart on the wind if they'd killed as many brave astronauts as NASA's federal bureaucracy has.
It's depressing that the Apollo program was 50 years ago. In 1968 when you looked back 50 years it was the Model T, zeppelins, and biplanes. Today we look back 50 years and it was astronauts going to the Moon.
Today we have rockets that literally land themselves. Not impressive in the same fashion, but I would be surprised if Rocketdyne F1 engineers wouldn't be impressed in the slightest

@@lukefreeman828 but it is... the technology that spacex are using has been around for decades they just took the plunge into actually commercialising a reusable/refurbishable first stage.
Back to see this video again, two years later, and it still mesmerizes with a wave of goose bumps. The immensity of power, awesomeness and technical achievement is beyond extraordinary.
Note the very sooty smoke from the burning RP1 kerosine fuel that is first in the rocket blast stream to come out of the bell nozzles and then becomes clean, bright burning flame. That is because the lower temperature exhaust flame from the turbo pumps got pumped around the inner rim of the engines to cool them. However, within the core of the sooty smoke, is the hotter and cleaner burning flame in the middle of the flame column that soon blasts out through the bottom of the cooler, surrounding RP1 kerosine fed sooty flame to create the magnificent 700-foot long Saturn V trail of bright yellow flame that we all remember and loved so much. Yes, I am old enough to have remembered the moon shoots. I was a little child, but I remember it well. It's a shame that these mighty engines were never used again after they were used to launch Sky Lab in May 1973. They should have upgraded and modernized them since they never ever failed on any of the Apollo missions.
The king of rocket engines. Man those things were big, loud and very powerful. The sound is unmistakable. Those things shook the air and the ground when fired.
Man, you get a real sense of the energy being released over those several seconds when the firmly mounted camera, probably 50 yards or more away, goes blurry and visibly shakes. What really blows my mind is to consider just how enormous a rocket explosion really is when full tanks of fuel and oxy go "boom."
To this date, 3/04/2019, I am still in awe of this mighty piece of machinery. My dad worked with one of the companies associated with the space program, so I grew up in awe of every step of the way. My biggest regret was not working towards the goal of being included in American space exploration. Much respect to all those that did, and God bless all that gave their lives during Shuttle missions.
I love watching documentaries and youtube channels (mostly by Scott Manley) that cover some of the older stuff like the problems that were encountered or new technology that needed to be invented on the spot... Still a hell of an amazing thing you did!
Have always been amazed with these engines that, based on the sheer volume of material being expelled from the engines, they were able to maintain a burn cycle and not be blown out.
I remember the house shook when they did that. Found out on the news that they had run a full power test of the booster. We were in Sherwood Park, about 10 miles from LH2, the test stand they did it at.
It did the same where I lived over in Jones Valley near Randolph school. You could be outside and feel and hear it. It almost got to seem pretty common back then.
@@schumifan78 thats for damn sure schumifan because with all 5 of those engines running, it had a soundwave output of 120 decibels which would rupture your ear drums if you were standing out there in the yard as far away from the test all the way down to the waterfront would still rupture your ear drums in turn making them bleed. It's because sound waves travel about 600 mph. But you wouldn't have to be close to the stand and you could put on those hearing protectors and it STILL wouldn't do much good, you'd still lose your hearing but it wouldn't be as dramatic as it would be if you didn't have ear protection. Not only that but the sound pressure would be so intense that it make your entire body vibrate.
Often missed here is that it's not just the awesome raw power but the unreal precision of the thrust that each engine must have within a few mere pounds of thrust which must be in absolute sync to maintain a perfectly level platform for the rocket as it rises. It's like lifting a baseball bat on the tip of one finger all the way up! Incredible!
It's actually all controlled by the gyro platform located in the Instrumentation Unit up on top of the third stage. If the rocket starts to tip over the gyro platform senses it and moves the engines to compensate.
There are two large hydraulic cylinders attached to each of the four outboard engines. The center engine is fixed and does not move. As the two hydraulic cylinders move in and out they swing the engines side to side back and forth. The cylinders are moved using pressurized rocket fuel tapped off the fuel pumps. The movements of the engines are controlled by the Instrumentation Unit sitting on top of the third stage.
Actually, @@cod6guy12, I remember an interesting on-air comment by Walter Cronkite to the effect that, having watched a nuclear explosion live in the Nevada desert and a Saturn V launch live at Cape Canaveral, the Saturn V was in fact louder. Of course it all hinges on things like atmospherics, observer distance, etc... but still mighty impressive.
@@russells9687 Indeed there are several factors that could've caused him to make that observation. The biggest one would be distance - He would've been much closer to the Saturn V than he was to the nuclear explosion. If you stood at a set distance from both of these things, both of them equally far away from your position, the nuclear explosion would always be louder. The Saturn-V's noise comes from its 5 F-1 Engines. The F-1 was very large and powerful for a rocket engine but the combustion that took place inside was nowhere near comparable in strength to a nuclear bomb, even when you fire 5 at once.
The M-1 engine is technically the most powerful engine ever, but never made it to a rocket. The F-1 beat it in terms of reliability and efficiency. The M-1 is a lesser-known engine that is not mentioned much...
The proposed Sea Dragon had the most powerful engine BUT IT WAS NEVER MANUFACTURED. Maybe NASA and SpaceX might build the sea dragon within 10 years from now....
If you listen carefully before firing, you'll hear the turbines spinning in the turbopumps. A gasp of air before trumpeting hellfire. Terrifying the amount of kinetic energy in those things.
I always feel like I was cheated somehow out of ever seeing a launch in person. Finally saw the very last Shuttle night launch just by luck. We were at Disney and heard the launch was 2 hours away, so we hurried and got down to Canaveral just in time. Awesome! But I still wish it had been a Saturn V launch.
Thats because they weren't restricted in the type of fuel they could use back then.. These babies used raw Kerosene and Liquid Oxygen! Today they are considered totally 'non-green' which is understandable.. Each firing probably puts out more CO2 than a small volcanic eruption! I believe the Ruskies still use engines that burn kerosene tho...
If you watch at 7:30 real close you can see the exhaust from the turbo pump coming out of the nozzle extension left to right on the center motor right before the hypergolic cartridge lights main ignition. Sweeet, what a machine!
Not quite. An olympic size swimming pool is about 660.000 gallons. The Saturn V first stage consumed about 200.000 gallons in 2.5 minutes. Meaning in 20 seconds, the Saturn V first stage would burn about 26000 gallons, or 4% of an olympic size swimming pool.
@@captainoblivious_yt An olympic pool is 660,000 gallons. The Five engines on the Saturn V consumed a total of 3,357 gallons of propellant per second. So they would empty an olympic pool in 196 seconds.
ByteMe Oh yes. The ground shook so hard I almost fell on my little 10 year old ass. My sister Dora and I were staying with my oldest sister Sylvia and her hubby John in Huntsville one mid 60's summer. John worked for Boeing at the time, and he took us all to one of those Saturn 5 booster tests. Their 5 year old son Joe is what I remember the most, who did as you say, screamed hysterically, did an about face and started hauling ass in the opposite direction.
To give you some perspective as to how powerful these engines are, you would need the combined output of 60 nuclear reactors or coal-fired power plants (each generating 1 GW) to match that of five F-1 engines. All this energy comes from pumping 15 tons of fuel into five combustion chambers... it's enormous.
Each engine's turbo-pump produced 55,000 horsepower... that's just the pump, feeding one engine. Over 1/4million horsepower, just to pump the fuel and oxidizer for the stage.
JORGE VELARDE it stands that it was 15 tons of the mixed oxygen with kerosene, yes, per second... During 2min40s of their work, that gives 2400 tons of fuel that was placed in the rocket...
+Zachary Henry Sorry, I never worked in Huntsville. During Apollo over 400,000 people worked in facilities and plants all over the U. S. In the years 1960-until 1974.
Thx for all your comments, sorry about the meanies. I find all this stuff fascinating when we didn't have all the computers and technical machines we have today!
Yep just think of how delicate a guidance and control problem that was. Pushing up on the bottom of the rocket nowhere near the Center of Gravity to direct its flight and doing so in a way to not overstress the shells of the rocket skin. Like balancing a pin on its head
+Martin Crane ~I don't know why you would call me son as i was alive when they built the Saturn 5 rockets and watched it happen live on TV. There's no reason to be disrespectful.
I dont think we will see any other rocket engines like this ever again. The trend is heading towards numerous smaller engines that are more efficient. Those engines were the largest most powerful to be successfully used.
I wonder how those engine gimbals work, its tremendous pressure the engines put out. The mechanism that powers the gimbals must be very powerful. I shall proceed to google this.
Thanks! And now it makes sense, since that turbo pump also moved the fuel at an incredible rate. Idk how I missed that. Lol. At any rate, thank you for the response!
Considering the size of the Saturn V, that test stand is unbelievably massive! Also unbelievable is these amazing engines were only used once and discarded. No wonder each Saturn V launch cost around $500,000,000 in 1969! About $2.5BN today.
Engineers in Huntsville, in a failed attempt to win the contract for the SLS side boosters (look up Pyros Booster) actually have designed a simpler updated version of the F-1 called the F-1B. It is expected to have even higher thrust (1.8 Million pounds instead of 1.5 million), uses far fewer parts (many of which are made from composites) and could be mass produced with more efficient modern manufacturing techniques for a fraction of the cost of the originals. NASA chose ATK instead to produce an elongated version of the solid fuel SRB from the shuttle program. Very sad decision in my opinion.
watch "moon machines the saturn 5' docu ... here you see also the actuall engineers who biuld this magnifecent machine .. still my favo docu of all time,incl the editing,music and most of all the people who were really there.. a big salute to all of them building something from scratch .. 😉👍😊
these F1 engines were so powerful they can kill you if you're standing 2000ft away. windows shattered 5 miles away. and when they 1st built these the noise even caused fires
Or the Sea Dragon, which is MUCH bigger with a single engine. Imagine the sea dragon engine being tested... It would probably cause major earthquakes...
the apollo project is just so freakishly impressive, almost scary, out of this world, can we do something like that again? btw, 9:44 the ultimate power, insane
Gotta start backwards and ask how a 22 ton crew capsule + service module, and an additional ~10 ton lunar module were able to bring a crew back to earth after leaving low lunar orbit, launching off the moon after spending a few days there, after having landed on it, after docking maneuvers and lunar orbit insertion, and a 3 day transit to the moon in the composite craft after extracting the lunar module from the Saturn V third stage, leaving low earth orbit, inserting into orbit after the second stage left the third stage transorbital and then the launch itself.
13.5 tons of fuel a second to be exact. That’s why stage 1 lasted only two minutes. And why the acceleration increased considering it was getting lighter so fast.
Really? Which was why the F-1 was designed and built by Rocketdyne by US engineers? In fact, it was an American engineer that designed the turbopumps, a piece of the system Von Braun and crew could never seem to get right on their own rockets. The only thing Von Braun or any other german scientist had to do with Apollo was coming up with the original concept of using a multistage launch system for a manned moon mission. Everything else was all US designed, US manufactured, and US operated. Learn your history, son.
Otto Knabe Remember one key thing... We never needed Von Braun. We took him because he was intelligent enough to surrender to us first instead of the Soviet Union. He was a propaganda tool more than a rocket scientist to us. Instead of hanging him, as he desereved for being a slave-labor profitting Nazi scumbag, we labeled him as "rocket Jesus" (no shit, look it up), as a propaganda tool. Not once did he design a damn thing that contributed to the US getting to the Moon other than the idea of it. Fuck Von Braun, may that Nazi son of a bitch burn in hell. Americans got America to the moon, not some shitbag Nazi.
Now THAT'S called rocket power! Don't make fun of NASA, or they just might unleash one of these beasts on you. That Saturn V was a literal volcano, it's no wonder that that was the golden age of space exploration. I say we revive the Apollo program, we need a manned moon landing (and a moon base) now more then ever.
Can anyone tell me how the SC-1 stage was connected to the test stand? I am constructing a scale model of the stand but can't find any information on the method of keeping the stage fixed in place.

JORGE VELARDE it stands that it was 15 tons of the mixed oxygen with kerosene, yes, per second... During 2min40s of their work, that gives 2400 tons of fuel that was placed in the rocket...
It's more like 13 tonnes of fuel AND oxidiser being burnt per second by all five engines.
From rare to well-done in the blink of an eye.
A helluva thing. As a 10 year old, I thought that this was the greatest thing ever made. Over 5 decades later, history has not proven me wrong.
“And we have liftoff of the tower-“
YESSSS!!! Music to my ears! 👏🏾👏🏾👍🏾👍🏾
Yes, this test was in Huntsville, Ala.
Did you know Earl Leroy Huss? He worked for IBM in Huntsville at NASA.
+Zachary Henry Sorry, I never worked in Huntsville. During Apollo over 400,000 people worked in facilities and plants all over the U. S. In the years 1960-until 1974.
+Zachary Henry There were 400,000 people working on Apollo. Do you have ANY idea od the number of people working on our space projects now!!! Ha! Ha!
+Sara Howard How many?
Thx for all your comments, sorry about the meanies. I find all this stuff fascinating when we didn't have all the computers and technical machines we have today!
Ah, the sweet old times when Rocketdyne was able to open the gate to hell by the flick of a switch...
hmm
9:22 The turbopumps starting up OMG it sounds like a siren
I guess I'm not the only one linked here through Ars.
Way cool, this is the first footage I have seen where they were testing the F1 engine gimbals control under real engine testing.
Yep just think of how delicate a guidance and control problem that was. Pushing up on the bottom of the rocket nowhere near the Center of Gravity to direct its flight and doing so in a way to not overstress the shells of the rocket skin. Like balancing a pin on its head
+Martin Crane ~I don't know why you would call me son as i was alive when they built the Saturn 5 rockets and watched it happen live on TV. There's no reason to be disrespectful.
My dad built the F-1s. At Rocketfyne in Canoga Park, when I was a kid.
I dont think we will see any other rocket engines like this ever again. The trend is heading towards numerous smaller engines that are more efficient. Those engines were the largest most powerful to be successfully used.
Literally all I can hear is Jeremy Clarkson screaming "POWEEEEEEEER"
A renaissance of American engineering never to be duplicated by anyone even by todays standards.
Awe inspiring, mesmerizing beauty.
Initiating Subwoofer test in 5...4...3...2...1...
ಠ_ಠ
This machine is insane , now is a dormant compared to all this HUGE power
8:48 you can hear the turbo pump start 1 second later the alarm stop
More engines, more power, more kerbals.
Those sirens sound just like the horn of the jet sled on trainz. #FoundTheSourceOfTheSoundEffect!
Still the most awesome rocket ever made by the USA.
This is epic and scary at the same time
I wonder how those engine gimbals work, its tremendous pressure the engines put out. The mechanism that powers the gimbals must be very powerful. I shall proceed to google this.
The gimbals were powered by pressurized LOX from the fuel tank after passing through the turbo pump.
Thanks! And now it makes sense, since that turbo pump also moved the fuel at an incredible rate. Idk how I missed that. Lol.
At any rate, thank you for the response!
I believe it was the RP-1, not the LOX.
" I shall proceed to google this."
Spock, if he were a millenial.
Great way of making use of unnecessarily high fuel pressure.
This is one of the greatest accomplishments in human history.
Considering the size of the Saturn V, that test stand is unbelievably massive! Also unbelievable is these amazing engines were only used once and discarded. No wonder each Saturn V launch cost around $500,000,000 in 1969! About $2.5BN today.
Engineers in Huntsville, in a failed attempt to win the contract for the SLS side boosters (look up Pyros Booster) actually have designed a simpler updated version of the F-1 called the F-1B. It is expected to have even higher thrust (1.8 Million pounds instead of 1.5 million), uses far fewer parts (many of which are made from composites) and could be mass produced with more efficient modern manufacturing techniques for a fraction of the cost of the originals. NASA chose ATK instead to produce an elongated version of the solid fuel SRB from the shuttle program. Very sad decision in my opinion.
watch "moon machines the saturn 5' docu ... here you see also the actuall engineers who biuld this magnifecent machine .. still my favo docu of all time,incl the editing,music and most of all the people who were really there.. a big salute to all of them building something from scratch .. 😉👍😊
Feel the POWER!!!!!
masterpiece of engineering!
I saw the test stand at Marshall Spaceflight Center, it is quite large.
Let's all give some live to the engineering that allowed the test stand to survive this.
Yes all! I met and talked with Dr. von Braun. My picture with him and me is on my Facebook page.
Damn! A day late...
Pure power of the saturn v
I saw this live. I was a kid.
Loved it
Just love old gernan-american
rocket teck. My father parts for those.!
these F1 engines were so powerful they can kill you if you're standing 2000ft away. windows shattered 5 miles away. and when they 1st built these the noise even caused fires
That;s brissilance for you.
Can you imagine the M-1 engine being tested? Or 5 of them??? Google the m-1 if u dont know what I'm saying
Or the Sea Dragon, which is MUCH bigger with a single engine. Imagine the sea dragon engine being tested... It would probably cause major earthquakes...
I love how you can hear the turbo pumps spooling up. i am surprised this test didnt slow the rotation of earth LOL
That test stand appears to be roughly 25 meters high.. Boca Chica (starship) OLM flame deflector comes to mind ..
Think about it : all those marvel were build without computers !
+maverickaegis76 yeap. Not built with computers, but with Nazi's.
They had computers, albeit nowhere near powerful as today, they still were featured in the manufacturing.
Was sent here by ArsTechnica :D
Siren sounds good too😁
So that is how they did it👍🚀
Merci !
Wow
the apollo project is just so freakishly impressive, almost scary, out of this world, can we do something like that again? btw, 9:44 the ultimate power, insane
The sirens make it!
My understanding that when a Saturn V launched the ground shook for several miles
That's the meanest bell tower!
Ain't no bats in that belfry! :D
Sara; Were you employed at Stennis or Marshall Space Centers?
It's absolutely mind boggling just how big of a machine is required to get only 3 people to the moon.
Gotta start backwards and ask how a 22 ton crew capsule + service module, and an additional ~10 ton lunar module were able to bring a crew back to earth after leaving low lunar orbit, launching off the moon after spending a few days there, after having landed on it, after docking maneuvers and lunar orbit insertion, and a 3 day transit to the moon in the composite craft after extracting the lunar module from the Saturn V third stage, leaving low earth orbit, inserting into orbit after the second stage left the third stage transorbital and then the launch itself.
13.5 tons of fuel a second to be exact. That’s why stage 1 lasted only two minutes. And why the acceleration increased considering it was getting lighter so fast.
It slowed the earth’s rotation
How far away from these engines would you have to be to safely watch the test and are these louder than the rockets they launch today?
When America made stuff.............
Really? Which was why the F-1 was designed and built by Rocketdyne by US engineers? In fact, it was an American engineer that designed the turbopumps, a piece of the system Von Braun and crew could never seem to get right on their own rockets.
The only thing Von Braun or any other german scientist had to do with Apollo was coming up with the original concept of using a multistage launch system for a manned moon mission. Everything else was all US designed, US manufactured, and US operated.
Learn your history, son.
Heh, it was developed in the late 1950s and used from the 60s and the 70s.. WW2 was over boi, no concentration camp for u
Otto Knabe Show me one single verifiable source that backs you claim then.
MrCoffee1976
I meant to adress Ian, I just looked up an article of the F-1 engine on Wikipedia
Otto Knabe Remember one key thing... We never needed Von Braun. We took him because he was intelligent enough to surrender to us first instead of the Soviet Union. He was a propaganda tool more than a rocket scientist to us. Instead of hanging him, as he desereved for being a slave-labor profitting Nazi scumbag, we labeled him as "rocket Jesus" (no shit, look it up), as a propaganda tool. Not once did he design a damn thing that contributed to the US getting to the Moon other than the idea of it.
Fuck Von Braun, may that Nazi son of a bitch burn in hell. Americans got America to the moon, not some shitbag Nazi.
Its not the sound that kills, its the constant powerful shockwave
Now THAT'S called rocket power! Don't make fun of NASA, or they just might unleash one of these beasts on you. That Saturn V was a literal volcano, it's no wonder that that was the golden age of space exploration. I say we revive the Apollo program, we need a manned moon landing (and a moon base) now more then ever.
I wonder how much each of the 'legs' of that test stand had to weigh in order to keep the whole thing from taking off!! WOW!
Can anyone tell me how the SC-1 stage was connected to the test stand?
I am constructing a scale model of the stand but can't find any information on the method of keeping the stage fixed in place.
