And don't forget the engine in the van that took them to the pad.
Also the one that propelled the elevator in the launch tower.
What about the three electric motors that powered their life support?
😂 facts
Oh, and the turbo pumps in the Rockets
@Tom Musial don’t forget the engines on the helicopter that retrieved their capsule from the ocean
It's so cool to see such a lovely young lady with an IQ talking about my dad's engines. When I was 8 to 10 years old or so, mid 60s, my dad was a leadman of a crew building the F-1 engines. I got to see one up close in the factory when I was 10.
There was a walkway around the inside wail about 3 stories up. My dad took me up to his desk on that walkway. He could see the whole plant. There was a hole in the floor under his desk where the very top of an F-1 stuck through and became his footstool.
These engines put out 32 million horsepower, or 7.5 million lbs of thrust. There were 5 on the rocket.
65 were built that were never used.
where did they put all that hay for them horses? 🤔
Amy riding the rocket was AWESOME!
I hesitate to say this because I don't want to detract from the wonderful narratives that Amy gives us, nor do I want to intimate that she is anything but a knowledgeable and professional commentator, but: is it just me or has Amy really upped the cuteness quotient?
So it took 83 engines to get to the Moon AND back!
Nyt Mare 😂😂😂
83 engines AND motors
John Ryan Then my job here is done
One could argue the astronauts were not going to willing go on a one way trip, and thus the 13 additional motors needed to return were also needed to go.
I would have liked to be in the design meeting as the engineer brought up "Hey, we need to push the rocket forward a little to get the fuel to slosh back to the bottom of the tanks." Such a mundane problem that required a few more engine/motors to solve.
New concept to me, but sounds like they were relatively well understood. First used on the Thor-Agena rocket: en.wikipedia.org/wiki/Ullage_motor
Somewhere on UA-cam there's camera footage of the inside of the S-IVB during flight. You see the tank draining as the liquid hydrogen is used up, then floating free as the stage coasts, then dropping back as the ullage motors fire for a second burn. It's pretty cool.
Edit: In fact, here it is: ua-cam.com/video/mJzT2bBGVfo/v-deo.html
Thanks! The Saturn 1 kerosene tank footage is a lot shorter: ua-cam.com/video/fL-Oi9m2beA/v-deo.html
On a related note, one thing that Amy did not have time to mention or chose not to include, was that once they were in space, helium was used to the pressurize the fuel tanks, to keep the fuel where it was needed, at the fuel nozzles so that no air would get into the lines.
According to Wikipedia, almost all rocket engines (after launch) use helium pressurisation. The alternative use of turbo-pumps is only justified for the heavier first stage(s).
"Put a booster on it." The solution to every problem, apparently. This was awesome.
Those vintage style animations are really nice.
MISSED YOOOOOU!! Welcome back Amy. It feels like it's been forever.
Here's an idea for you Amy. How about an episode about all those Saturn first and second stages that fell into the Atlantic? Where they recovered? Where are they now? Any quirky stories?
The basic answer is no they were not recovered. They just fell into the ocean. The full answer is probably more complicated than that. I bet Amy would be able to tell us.
Jeff Bezos found Apollo 12 first stage some years back and the remains are in a museum.
They found parts of the first stage from Apollo 11 as well. The first stages were destroyed upon contact with the ocean. They hit the water at some 4,xxx mph. So they exploded upon contact then sank
4000 miles per hour? I don't think so. They were a hollow cylinder in free fall. Terminal velocity is much much less than that, more than 10 times less. Yes, I know it was going very fast when it separated, but the atmosphere would either burn it or slow it down.
Gabriel Braun that speed is a number that stands out to me. I believe I read that somewhere. Can't confirm or deny that speed through Google searching.
Woo Hoo! More Vintage Space!
Would wait to the moon and back.
Be well!
There is nothing better on youtube than such a beautiful gril talking about rocketry 😍😂
I love Space
I love AIDs.
Simply put, space rules. It is one of the few 'interests' one can have where the possibilities, thoughts, dreams and ideas are truly endless. You can and never will truly know everything or figure everything out. Our possibilities of thoughts are endless, just like the universe
Yayy new vintage space!!
I had no idea how many small rocket motors where on the Saturn V, Thanks Amy this was fascinating!
Your little last comment 'thanks for watching' was cute in the delivery!
You made me cry a little. With pride, damn it.
I never thought of the number of rockets on a Saturn and especially the extra staging motors and such . Thanks for the enlightening vid!
MrJackHackney The lego saturn v is a nice model abd stages come apart.
No one goes into so called space, like no one has ever been to the moon, it’s all just a firework show here in earth then cgi cartoons 😂
recently re-watched 'Apollo 13', (Netflix). I realized that your videos provided much more context than I had when I first watched it, circa '93. Thanks.
I'm a history nerd that nerds a bit of science on the side. You're my new favorite channel.
83 Engines and motors to get to the Moon, but a total of 88 on board the entire full stack Saturn V? That's a ton of propulsive power. Thanks for this video, Amy. I had never considered this angle of the Saturn V before.
-Brian
I have become more knowledgeable thanks to you, well done madam!
Amy, the S-IVB APU's had one ullage engine, two yaw & roll engines, and one pitch engine. That would make a total of 89.
APS*
And there were 2 of those modules.
I'm 3 years late, but hope someone will find this helpful
This channel is slowly becoming my favorite. She does an amazing job not only with material, but presentation too. Very well done.
500F is the best paint scheme. That black ring and the USA on the 1B style S4B just looks so vintage.
And that, ladies and germs, is why you'll often hear rocket scientists say of a successful launch - 10,000 things did _not_ go wrong!
Great vid. Could you do one on how they were supposed to use the nose cone protector and the other pointy bit in order to escape? I heard you mention something about that when you got to that bit being ejected and it's something I'd never heard about - and I'm old enough to remember watching some of the later Apollo missions take off and land - on the Moon and back home! Parents would wake me up and say I'd thank them one day. I had no idea what they were talking about back then LOL. And yes, I thanked them. Even I'm too young to remember watching Apollo 11 - I did watch it, apparently, but I couldn't tell you a thing about that day that hasn't since been on telly. I'd have been 2. I definitely remember the last one. I'm not sure I knew it was going to be the last one but I do remember thinking that it was about time that they had a scientist go onto the Moon and why had it taken so long. Maybe that's why the only science I can do is geology :-)
Amy did a video on the Q-Ball, which was the guidance system for the launch escape tower rocket. This video briefly covers your question: ua-cam.com/video/SDWEpNx05uA/v-deo.html
So which germ is your father? And what does that make you?
Basically, if anything goes wrong, the solid rocket motors on top of the command module pull it away from the rocket *fast*, so that it can parachute to safety. It was used once, and succesfully: a soviet rocket exploded seconds after the crew got away, and other than being badly bruised and having a really bad day they were fine.
Mam Amheus I
Yes! *Just* a little more! Maybe a vid on hypergolic fuels?
Including the WW2 German stuff (163 Komet and the Bader) .... C-Stoff, T-Stoff! Scary!
You always pull us in with that twinkly eyed, giddy enthusiasm of yours. As fascinating as our pet topic is, you could engender indrigue into vacuum cleaner troubleshooting and repair.
Oceans of charm and charisma flow from you.
Only thing left to say is,
Wow.
Also very impressive: the retraction of the eight umbilical arms on the LUT that had to retract at the right time or they would have interfered with the ascending Saturn V. So many systems had to work properly.
Holy crap you did my episode suggestion!
Amy, Have you done a detailed video on the design and fabrication of the Apollo ablative heat shield? It's quite interesting how NASA decided upon using novolac epoxy, which is basically a plastic compound to protect the spacecraft and crew from the intense heat of re-entry. Also you could contrast that with the heat shields used in the Mercury and Gemini spacecraft.
+Superior Planet Thanks, that looks like a great resource. 👍 Any ideas where I could find a detailed description/discussion of the construction and structure (with diagrams) of the Apollo command module?
I love how much you care about space
I can't get my head around the sheer complexity and engineering skill that made this happen. My Birthday is August 5th, which I like a lot. An excellent video. I learned something.
Love your vids Amy, could you make one about the NERVA engines, and maybe your opinions on nuclear rocket propulsion? :D
Second that notion!
Yes pls.
For some reason, the coolest sequence to me is the eight motors firing to create the specific impulse necessary to saturate the fuel feed lines for the main engine of the second stage to start. Maybe its just the usage of motors to prime the engines. It's cool, but I wonder if there was some way they could get it to work with compressed gas and one way valves or something.
If there was an easier way, they would have tried! Star Trek, Scotty: I canna change the law of physics! Wikipedia gives a good explanation: en.wikipedia.org/wiki/Ullage_motor
Sweet!
On the LEM and the CSM they just used the RCS engines for ullage. On the heavier parts you need more thrust, hence all the solid motors.
Can work just fine with pressurised gas thrusters, that's what the second stage of SpaceX's Falcon rockets uses. (Nitrogen, in their case.)
The easiest way is hot staging, which is what Soyuz uses. You simply build an open interstage, and ignite the second stage before the first stage finishes burning. Or, on the spacecraft, you have the main propellant tanks feed a smaller sump tank that in turn feeds the engine. That way, as long as the sump tank is full you don't need to do a ullage burn.
Every day is a school day.
Fascinating information wets my appetite for more information.
That model is soooo cool!!!
When I saw the title I thought they'd got through that many F-1s during testing!
That has nothing to do with my comment.
itsabig you’re thinking of the V-1, not F-1
i have that same model!
i broke it....
clayman0 skycade A minute of silent of a great model.
honestly it's a 10/10 model if you have an exacto knife
4/10 if no exacto knife
What is this model? Name? Thank you.
i don't actually know sorry!
i got it from a gift shop in the museum in Washington DC.
i found it on ebay for a really high price
i'll continue looking
okay it's called the "inair e-z build model kit saturn V"
search that and you should find it
83?! Who knew!? Well done, Amy.
Smart,sense of humor, loves space and cute to boot excellent job...
Thanks for the video, I never really gave much thought to liquid fuels behavior in 0G but having some kind of engine thrusting the frame forward to get the fuel to clump up near pumps and etc sounds like an obvious thing when I think about it.
Magnus Bekkengen The Russians used the hot staging method to solve this problem. Fascinating stuff.
That is indeed why the Soyuz uses hot staging, and why the Atlas had that interesting stage-and-a-half configuration. No one was really keen on or confident in igniting engines in flight at the time.
These were called ullage burns and the saturn, the CSM and LM all used ullage burns. In fact the LM computer automatically added a 7.5 second RCS ullage before descent engine firings to reduce the workload of the crew.
Not really from slosh, but from the fact that the ascent engine was not gimballed, therefore the only way to steer was firing of the RCS, causing the rocking motion as it chased its target orbit.
Can anyone suggest a nice model for the Saturn V rocket that comes apart and shows all the stages? I really want to own one to show my kids (when I get them).
The Lego model is very high quality. Separates into all the stages, tons of details. Impressive size. $120. Highly recommend it. Make sure you don't accidentally get the lower quality "Lepin" Chinese knock-off.
I have one of those too. Its nearly 2000 pieces so its a good 5-6 hour build.
Very impressed with the little details they managed to get into the lego kit.
The Airfix brand Saturn 5 kit is good.
Kevin Moore It's 1969 pieces, get it? 1969 😏
The answer is: "it depends." One choice already mentioned is the Lego model. Not too hard to find, but expensive. On the other hand it's pre-painted and no glue is required. ~1/110 scale. I prefer other solutions because it is obviously a Lego kit. Usually runs $120-$140.
Airfix is a good choice. 1/144 scale, hard to find, slightly more accurate than the Revell/Monogram kit. Runs about the same price as the Revell/Monogram kit at $60 + shipping, depending on seller.
Then there is the famous Revell/Monogram kit. 1/144, based on the Block 1 design, so the command module is not accurate, and the paint instructions match the first series. She did a video on that paint scheme at one point. :) Easy to fix, and the model is designed to come apart stage by stage, as is the Airfix kit. Usually found about $60 + shipping.
If you're willing to spend the $$$ to get the Lego kit, you might want to look at the Dragon Saturn V kit. It's a whopping 1/72 scale, price runs close to the Lego kit.
There's the AMT kit. It's 1/200. One version has all the manned boosters from Mercury to Saturn 1b and Saturn V, and the other is a Saturn V by itself. The former is much more expensive. The latter runs around $20-$25 + shipping. The quality & accuracy are good, even if it's smaller. Actually the inter-stage sections are more accurate than the bigger Revell/Monogram kit.
Finally there are some small-scale (c. 1/300 or so) toys which feature separating stages, if you don't mind the small size.
The Saturn V - Apollo combination was so complex. With all those 83 motors and engines, the one I most am impressed with is the LM ascent stage engine for which there was no back-up and that had to fire for almost 10 minutes to take the LM ascent stage to an altitude and at a spped over the Moon sufficient to dock with the orbiting CM. Fortunately, that ascent stage engine did not fail ever when needed.
Wow, nice to see you again
Could the arms from the tower actually hold down the Saturn V at full thrust? I'd imagine not, but I only ever assumed those arms were for umbilicals and perhaps balance.
The arms up the side of the rocket are indeed for umbilicals topping off the tanks till the moment of launch. Look up "Saturn V launch camera E-8" That will show you four very sturdy hold down arms used to keep the beast locked down till go-time.
There were hold down arms at the base of the rocket that kept it on the pad until it (just) achieved full thrust. These could not hold it down indefinitely, though, and released as soon as full thrust was achieved.
katie_incredible The initial acceleration of the Saturn V was one of the most gentle of all rockets, with engine thrust barely exceeding the weight of the fully fueled rocket at takeoff. The force needed to hold it onto the pad would have been a relatively small fraction of the rocket thrust.
The thrust at liftoff was 7.5 million pounds, with a fully fueled Saturn V weighing 6.1 million pounds. So the four hold down arms restrained 1.4 million pounds of upwardsness, an impressive feat!
And from the time fueling was complete up until engine ignition, they had to withstand 6.1 million pounds of downwardness. That's even harder. The hardest thing was making absolutely sure they released simultaneously, if even one had been the slightest bit late, the rocket would've pitched over in that direction.
I posted this on your last video, but just in case you didn't see it, I have an idea that I think would be a lot of fun. It could be called something like "Movie night with Amy". You watch a movie on YT live and provide commentary. You won't show the movie (pretty sure YT would have a problem with that), so other folks watching would need their own copy. You could do movies such as Apollo 13 and the Right Stuff, or some fiction movies such as The Martian. Special guests could make it even more fun!
That would be a waste of her precious research time. We need her to use her sexy geek time PROPERLY and do REAL research.
That's her brand and that's why WE LOVE HER. That's what made her famous.
That's why the majority of us is here for. We need her historian geeky smart-fu powers. We need her to analyze the records "WITH SCIENCE" :).
Not to be provided with childish retarded comments on retarded movies like The Martian ,Apollo 13 or fuck know what else. For that we have the muppets from What The Flick?! (run a search on them). There's plenty of retards on UA-cam doing giggly reviews of a even more retarded brain dead movies.
Skip Morrow - I'll second that. Gorilla No Baka - actually no, I was taught that if you can't say anything nice, say nothing at all. So as a friendly suggestion I'd recommend visiting grammarly.com
Very funny!
Good to have you back!
Glad to see a new video Amy!!!
Where was Pete? I hope he's well.
Pete! Pete! Pete!
@5:30 The flight back to the moon? 😋
Niall Kinsella lol
haha good one
She meant back to the studio (Mr. Kubrick's waiting) :D
Speako!
You always look so proud when you're just about to finish your dialogue. I really enjoy seeing that. You do us a great service, Amy. Keep it up! I love this channel!
Wow, that is some massively complex engineering.
I pull my ketchup out of the refrigerator, make sure the top's firmly closed, and give it a short shake, which pushes the content closer to the applicator.
Is that ULLAGE?
Amy...you are the fuel for my own F1 engines...and you take me further than the stars in the most distant galaxy. What do you think about that?
O.K....I'll leave out all queries out next time. :)
You are such a charming young lady, and your passion for the history of spaceflight makes you even more endearing. As always, I look forward to your vids and the knowledge you share online. Stay on it, girl
You’re just like a Saturn V Amy, fricking AWESOME!!!!!
According to cospiracy theorists, it took a couple of liter of gasoline to get to Hollywood and fake the landing.
Cospiracy, is that about cosplaying pirates? ;)
sesc79 yes!!!
53 engines actually because that's all they needs to get to the moon and back
they really only needed 36 though
Where in the world are you getting these numbers?
53 incase of mistakes but this is for entering the sphere of influence of the moon not landing aka going to the moon
You are correct on the 53 engines were needed to get to the moon 'and back' as in Apollo 8 style. But 36???
ken assuming you do it perfectly only 36 because they put the craft on a trajectory to go to the moon and in case something fails they'll flyby and return
so if you get that trajectory perfectly with no need for corrections you can go to the moon then just glide back
I believe then the number would be 38. Two roll thrusters would have been fired on the SM to even out the Sun's heating effect on the SM/CM.
I've had this exact question in the back of my mind for a long time. Thanks for answering it!
It's amazing what you can do on a budget.
You're so beautiful that it's hard to concentrate on what you're talking about.
DATING HARLEY QUINN 😂
Get a girlfriend.
Actually Amy does not do a whole lot for me. Why? Because I tend to compartmentalize. I work with a lot of good looking women. Also, your avatar is named after a psychotic murder in the batman world, perhaps you'd think one of those Manson women were cute, too. Me? I'm watching a new era in space exploration starting. Amy is talking about the 50+ year old Saturn system. She also spent a lot of time making excuses for the SLS not launching. Given that NASA is merely adapting proven engines and technology from the Shuttle to the SLS it's rather distressing that $20 billion a year over 7 years has not produced a flight. SpaceX and the Russians do more in a year than NASA's other expendable vehicles combined.
I was hoping that Amy would spend a little time on Falcon Heavy. Also, I was a kid when we went to the moon and 95% of the stuff she talks about I already knew decades past.
This video has more double-entendres than all the Carry On movies, but that's science!
As always great video! I love the little things that you wont see normally on TV.
Great video Amy.
incredible explanation! great work Vintage Space!
Keep up the great vids young lady, you always brighten my day when i watch a vid.
_THIS_ is the shtuff I love, Thank you Amy!
According to your title, the correct answer is 70 "to" the Moon. The other engines were for coming "from" the Moon. I like being picky. Love your shows.
Glad that see a new video from you
As always, thank you for a well made, informative video. I look forward to your next upload.
I had no idea 1) so many motors/engines were used, and 2) the actual difference between a rocket engine and motor. Awesome video!
Glad you're back.
Awesome, excellent, and outstanding, per usual.
The camera view inside the tank during staging separation should have been used to describe the fuel slosh in microgravity. Always a favorite of mine.
You have a good and professional way to present your videos. You also explains very well. Wonderfull! I'm not gonna lose any of your videos from now on.
Great video. Much easier to watch than some of your (earlier) videos where every millisecond of unspoken video was cut out. Great subject too. Love the Moon vehicle.
THANK YOU - very informative
HAPPY NEW YEAR
Thank you for a great video, I never knew about all the small retro engines on the various stages of the rocket.
Excellent as always Amy!
I sure miss your show,
Brilliant. Thank you Amy
I just recently found your channel and I love your videos as a jumping off point for my own space nerd research. Really cool to see that you are still updating your channel! :)
Hope you are well Amy, keep up the good work.
Very clear presentation, well done!
Great video. It's amazing how much Engineering went into those machines.
I love seeing documents about the apollo missions . i remember seeing Apollo 8 lift off. And enjoy seeing this beautiful host explaining the technical illustration. Great video.
wow that's awesome who knew they had so many engines!!! don't stop this stuff is unbelievable more power to you girl i salute you
Great video, as always. Keep 'em coming Amy! :)
You are awesome, Amy. I have followed the Space Program since Alan Shepard in great detail and I consistently learn more from you each week. Thank you, John
This was a fantastic piece of engineering... and a fantastic presentation.
Continue the good job Amy.
Hey Amy ! Missed your videos, thanks for explaining and describing How much work and techs détails. I always wondered only on the first stage, never the rest. Anyway thanks So much and keep up ! Much love
Great coverage!
Yay your back Amy your videos are the only one I like before I even watch them
Excellent video, as always!
Another great video. and, of course, eyes to die for.
Loved this. Had seen Scott Manley's Saturn V video where he walked through most of the motors, but way more fun when you count them up. A much larger number than I was expecting!
Great vid 🛩
So, it was really 88. Just like the keys on a Piano.
(Although, the F1 engines, just a tiny bit stronger
than a Piano.)
Amy, sorry, I missed this when you posted it. I
just found it.
THANK YOU!
Glad to see you back.
steve
Great video like always!
Just found your channel (through someone recommending it in the comment section of one of EverydayAstronaut's videos) and must say that THIS IS AWESOME. Can't wait to watch all your videos :)
Thanks for doing this one Amy. It put a request in for it a while back...
