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.

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.
@gordonrichardson29726 жыл бұрын
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).

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.

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.

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.

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.

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.

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.
@gordonrichardson29726 жыл бұрын
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.
@KevinT31416 жыл бұрын
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!
@KingdaToro6 жыл бұрын
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.

Again, a re-evaluation was done and it was determined that the S-II had enough ullage on its' own, so the ullage motors on the engine skirt could be eliminated altogether starting with Apollo 15. With the first "J" mission, weight needed to be conserved with the addition of the Lunar Roving Vehicle. Also, four retros in the S-1C were also eliminated. This caused the S-II engines to ignite too close to the jettisoned S-1C, causing the top of the S-1C's LOX tank to be scorched and caused a "secondary plume." The other 4 retros were restored to Apollos 16 and 17.

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!

Amy I never thought about the precise number of propulsion systems on one mission. Realy was amazed by the number. Tks info was very well given and I wondered when you whould stop listing. Tks loved vid

As you say Amy, this video really made me appreciate the awesomeness of the Saturn 5. Also, thanks for clarifying the difference between a rock engine and a rotor motor. I look forward to your future videos.

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

Small little nitpick. On the toy model you use to demonstrate in the video, the Interstage ring is actually represented as part of the structure of the second stage with the engines attached incorrectly at the end. The ring you point to as the interstage ring on the S1-C is just part of the structure of the first stage, it didn't separate. The corrugated ring with the long black stripes on the second stage is the actual location of the interstage, but the main J-2 engines on the second stage would be "inside" that on the end of the S-II rather than on the bottom of the interstage. I have that same toy Saturn V and there's a good reason why I don't take it apart! Of course the interstage on the SII/SIV-B separation stays attached to the SII because the SIVB has its own ullage motors, which had to stay attached as the SIV-B needed to reignite. The SIV-B had two Aux propulsion system modules, but each of those motors had three engines and an ullage motor each. I believe that's in addition to two or three other ullage motors, but I'm not sure. I could have sworn that the SIV-B had three aux prop modules but I can't find any photographic evidence to back that up.

I went into this thinking I already knew everything, but somehow I didn’t know that the second stage srm’s were attached to the interstage, not to the outer frame. I always wondered why they had the weird interstate separation but now I know. Thanks!

Check your Staging! I believe that this number varied from landing mission to mission, at least as far as the ullage and stage separation motors were concerned. I believe there were different configurations of these that were used in later flights.

Not sure if you've already done this, but I found a rather dry video from NASA from the old days explaining how they actually fly the capsule into the atmosphere and direct it to its splashdown target by changing its attitude. Very interesting and no one ever talks about it. Maybe you could do it and make it interesting. Thanks!

Amy. It took 89 rocket motors and engines to do the job; not 83. You missed 6 engines in the S-IVB Auxiliary Propulsion Systems. Each of the two APS’s had 4 engines, not 1. Each APS had one 310 N ullage engine and three 670 N roll, pitch and yaw engines (similar to the RPS engines on the SM and LM) to point the S-IVB/Apollo stack in the right direction for TLI, and to point the spent S-IVB in the right direction to fly away from the Apollo after the LM was removed. Surprise! Keep up the good work. I really enjoy your videos.

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.
