- Geoff Nunn, the Adjunct Curator for Space History at Seattle's Museum of Flight gives a sneak peek at the Apollo F-1 engine parts that will be in the museum's galleries next year. These engines were recovered from the bottom of the Atlantic Ocean decades after the Apollo moon missions.
My dad built those engines. Probably even the one in this video. Built in Canoga Park, CA. I was 10 when he took me to a family day to show them to me. They were huge. I got to touch one. He was a supervisor and had a desk on a catwalk about three stories up inside the building. There was a hole in the floor under his desk. An engine's very top stuck through and he used it for a footstool.
I was at the launch of Apollo 17. I was about 12 or 13 then. I saw my dad's engines light the midnight sky like full sun. It was like daylight, except the red hue. 32 million horsepower. each!
Lucky mo-fo!
Nice! Very cool! My dad worked on the 3rd stage of the Saturn V - Drew up the blueprints (drafting) for it's manufacture.
If I could give you more than one like, you'd have a whole pile from me. Very cool.
My grand father helped enrich the Uranium at Oakridge Tennessee that we used to nuke the Japanese.
All these family members of people here in the comments, so cool! My grandfather ate the first ever Egg McMuffin to ever come out of a McDonalds, I know, not as special as your relatives accomplishments. Lol
Whatever damage was done to those engines was probably done when impacting the ocean surface not the sea floor.
Impacting water at terminal velocity is like impacting concrete.
True and the S-IC probably impacted with the ocean engines first as that's how it would orientate itself during free fall.
I don't know what I would have done had you not explained, in great detail which end the thrust came out of.
My first girlfriend said the same thing.....................
If the fire-end points toward space you are having a bad problem and will not going to space today.
Interesting fact: those barriers you see on the injector plate were a major addition that was added late in the engine design. Without them, the engine would pulse so badly it would almost self-destruct. When they added those barriers onto the plate, it made the engine run as smooth as silk.
Fun fact. at 2:48 the reason why the part broke off there is because during welding, the mechanical properties of the parent material change due to the high heat which make it weaker. We call it the "heat affected zone". Even the weld itself is stronger than the parent material. Source: It's my job to know this stuff.
HAZ baby!
wow, never thought these would ever be seen again
Very cool. I grew up during Mankind's greatest adventure and was twelve when Apollo 11 landed on the moon.
Must have been awesome. I missed it. Maybe we'll both get to see a Mars Adventure ( Man's 2nd great adventure ).
God damn Christianity!
If we didn't have religions we would have the 3rd generation of Martians being born, on-planet, already.
I was also 13 at the time and I had been into astronomy for 6 years at the time also. I had Star charts taped all over my bedroom ceiling and a 5" telescope that I used to watch a little white dot called Apollo 11 as it made its way to the Moon. Absolutely fascinating days, but to think, that each of these engineering marvels were only used ONCE and then destroyed as they returned to Earth, what a waste!
yes-i was there too. if i recall-the wonderful world of color and marlin perkins was pre-empted that night. black and white teevee showed me everything i needed to see that night. never will forget.
We grew up during mankinds greatest hoax!
The amazing thing is they were pretty much made by hand. 5,000 part welded into 1 engine and they worked like a dream.
the more amazing thing is because they were made by hand, and the know-how died with the machinists, and workers and engineers passing away, we are unable to build F1s now. regular blueprints are there, but is not enough to build a functioning engine. so now we use Russian RD 180 (which are incredible)
But we can mass produce a full flow staged combustion engine now
@ARXDMOS They are not very practical or eficient.
They are just pure power.
Apollo 12 was the fourth mission to the moon, the second landing.
Everyone clearly knows that, stop arguing semantics on RUclips
@@smudent2010 Facts, not semantics.
@@kenchorney2724 lol ok there bud. You see the detail he is speaking of with the F1? He clearly knows his stuff and clearly means the second mission to land on the moon. You're just someone who thinks arguing semantics on the internet is evidence of intelligence when it is exactly the opposite
@@smudent2010 hear, here !
So glad that there are people who retrieve and display these fantastic artifacts from early space exploration.
Most people have no idea of the amount of POWER those engines were capable of.
While inefficient by today's standards, those engines are still amazing.
Imagine being a fisherman and watching this enormous junk-heap falling from space and crashing down into the ocean. Wish they had footage of that!
Imagine being a fisherman and watching it come straight at you!
"Sorry. The sea is closed."
"The what is what?"
I'm sure they had Navy keep that area of the Atlantic clear of boats.
My classmate in medical school was a captain in the army and an engineer. He worked on the design and debugging of the F1. When they had finally solved the vibration resonance problem and the engine was approved for production, there was a big, celebratory dinner. Hundreds of people who had worked on the engine program. At the end, there was an awards ceremony and one of the sheets that each person was handed was a pink slip. They were now unemployed.
The" Real Rocket Men " from yesteryear using slide rulers and scratch pads. Technology in the the 60's was with the most brilliant minds ever, not like now with a CAD program pushing buttons but have no clue on metal or material characteristic. Hands on production , amazing Apollo program in whole not just the awesome F- 1 engine but the creative minds like Mr. Holbolt coming up with LOR - Lunar Orbit Rondevu which only way to land on the moon.
National Air and Space Museum in Washington DC has a fully assembled F1 engine with the bell on exhibit. ITS AWESOME
I've gone and looked at the one at the Aerojet facility in Canoga Park....a damnned impressive structure. 19 feet tall from the base of the engine bell to the top of the structure.
I’m pretty sure I’ve seen one at KSC down in Florida as well as in Huntsville, AL at the Davidson Center. Hopefully they have them scattered across the country for everyone to get a chance to see them.
❤️🚀
@@lukeoftheskythatsometimesw8253 Im Betty sure you havent lol
@@joeyoliver579 Kennedy and Huntsville each have 5 F1 engines on display. They just happen to be attached to booster test articles, not stand alone.
Impact with the sea surface would cause the damage. Not impact with the sea floor.
Have you seen the pictures of the Titanic? The prow, which never impacted on the iceberg, is bent upwards to a significant degree!
@@amanofmanyparts9120 The Titanic didn't hit the water at supersonic speeds
Solexx X the engines clearly weigh a ton or more easily. Maybe thats why its in good condition, good engineering, good manufacturing USA USA!
@@blurglide Neither did those F1's.
@Craig Wall They nearly did it if not at supersonic
Cool i remember as an 8 year old boy watching the moon landing on black and white tv in England.
Those F-1 engines were practically hand built, with individual notes on their fabrication, which is one reason why they were never built again. Once the program closed and the craftsmen retired or died off, that information was lost... Amazing job at removing the barnacles and the other crap. I wish he would have covered that process. They should reconstruct a dummy expansion bell to cover for the one that was destroyed from the ocean impact.
Another view of a fascinating time in history
Good report!! One of the most impressive space tech stats to me came from Arthur C. Clarke in "Prelude To Space" where he cites that just the FUEL PUMPS of the Saturn V were more powerful than the most powerful engines that drove ocean liners around at the time. Can't but help be impressed by what was accomplished fifty years ago! Harkens that the SR-71 Blackbird also built in that era is STILL the fastest jet plane ever built!
At first I thought, "who put the mic I this guys hand?" Then I realized the name of the channel.
good reporter, i like how he gets down all the right questions and answers
Neat, I saw Apollo 16 launch, it was loud.
An interesting thing is that parts of that LOX dome welded together seem to be made of slightly different alloy grades. Some of them corroded, and some were not touched by corrosion at all.
Same for the corrosion pattern on the kerosene ring. It suggests that the source alloy may not have been completely uniform.
Yeah, precisely one part, from weld to weld, is rotten. Strange.
I'm sure there is a lot to learn regarding aging of space technology in harsh environment by studying these artifacts. Could even helps overcome technical problem on long duration mission on other planets.
Alexagrigorieff You are probably right but do you think that maybe certain areas were buried in silt and protected from corrosion to some degree?
I thought so at first but it's obviously (look at 5:42 ) only one panel that precisely had rusted.
I see your point, its just that one panel. It must have been the Friday afternoon shift at the foundry.
Different forming and heat treating processes on 2 pieces of the exact same alloy can affect the crystal structure and thus the corrosion resistance. Once cracks open up, the part is doomed to rapid deterioration. In salt water you also have to consider electrolytic effects when different metals are touching
You can see the cooling channels in the wall of the nozzle, so cool. They have one at the Smithsonian Air and Space Museum in DC.
I got to see this at that museum, it was really cool!
It would be fascinating to see HOW and WHEN (and perhaps even WHY) these Saturn V rocket engine parts were recovered from the ocean floor. Also, I'm wondering if their locations were found by chance, or were they intentionally being sought out? This technology was incredibly sophisticated and state-of-the-art at the time. Really neat video.
The WHY is because Jeff Bezos was obsessed and he’s rich enough to hire a specialized vessel to hunt for them. He must have got telemetry data from NASA to narrow his search
*”All I want for Christmas…is an F-1 rocket engine”*
Glad they found those and recovered them. I doubt the second stages are in such good shape.
Fossils of what used to be one hell of a country.
There is an intact F-1 engine at the Space Museum in Alamogordo, New Mexico. Look for the golden cube on the hill East side of town. They also have a copy of Prof. Goddard's first liquid fuel rocket. Neat place.
15 SaturnV ×5 F1 =75 F1 engines... 65 of those would be in the ocean, 300 miles far from KSC
Fueron porque tenian el Saturno V yes but only 13 flew. The other 2 are in museums .
Von Braun took the approach they had to be reliable, absolutely could not fail. So the design was brute force simplicity. I think only 1 of the engines malfunctioned slightly and produced slightly less thrust than expected or it shut down a bit early.
It would be great if a complete F1 could on display also, so much of the engine is missing.
I saw the first and last Moon landings and hope I live long enough to see the first Mars landing.
I was 7 when I witnessed the Apollo 11 landing. I hope, as well, live long enough to see humans walk on Mars.
@@josephstevens9888 It's really the only item on my bucket list.
When Armstrong stepped off the ladder of the LM. We were camping and a neighbour had a black and white TV with rabbit ears sitting on a picnic table and they invited me to watch though it was late.
The already poor picture from the moon was made much worse because of the rabbit ears but I was enthralled.
They say anyone who watched the first steps on the moon remembers what they were doing and where they were at the time. I certainly do. The camp was the now long gone Hammond street Campground, Bangor Maine, July 20 1969. I was ten.
When I worked on the f1 engine u was just a kid at 18 in 1963 but I learned a lot from fellow engineers. I have a picture of me with astronaut Walter Cunningham in front of the skirt of the f1. I was installing transducers and thermocouples.
Amazing technology. Today the United States doesn't really have any goals like they did back in the 1960's are 1970's. Now it about getting involved in other countries affairs, etc. Eion Musk is now doing much of the heavy lifting with his Space X Rockets, but only to the Space Station in space. Though it was exciting to be able to reuse an existing used rocket.
Yes...if we ever do go back to the moon and beyond it will be because of the efforts of Elon Musk,Jeff Bezos and others in the private sector , if we have to wait for the government it won't happen for a very long time-if ever.
best rocket engines ever made. the seafloor did not create the force damage, the water surface impact did that. the corrosion was the parts intimate contact with the ocean floor. So those parts up in the sea look pretty good still, except those iron valve stems. f1 engines would still be the copy to get us to a lunar colony, those huge solid fuel rockets make to much turbulence when burning. these engines were tested for destruction from sound waves. They used counter measures to keep the sound waves from swelling the burning chamber out of tolerance.
The best rocket engines ever made were the NK-33s and their derivatives like the RD-180. These engines were so good that NASA did not want to believe that the Soviet Union managed to make these engines not only viable, but extremely reliable aswell.
F1 engines beat these only by sheer thrust values, however the efficiency of the NK33 and RD180 engines were unmatched until SpaceX made the Merlin 1C engine.
As a sidenote: The RD171 engine was the single most powerful liquid fuel rocket engine ever made. Even more powerful than the F1.
So. I hate to admit this. But the best rocket engines ever made were Soviet made. Until now.
My father told me before he passed that they built 65 engines that were never used. That's 13 missions that never happened. Issac Asmonov, the writer, proposed we use an F-1 to help get to Mars. Power it up After getting to space to get a huge push.
Awesome!! I cant believe back 50 yrs ago, the technology was this good but what happend today?
Cool video. I wish I could make it out there when the Apollo 11 command module goes on display.
Cool.. thanks 👍
Next time pick a person whom actually knows what he’s looking at.
Yea he is a dumb ass
“Whom” … nice 👊🏽💥
That manifold surface in the beginning of the video is not from corrosion….it was melted away on reentry !
@@leeryberg5192how can you tell? Why would parts of it be melted and other parts pristine?
No I think he is fairly knowledgeable. Your comment is inaccurate and unnecessary.
Fun fact. They can’t get back to the moon using this same technology? Why? This was made by hand and they simply don’t have the knowledge to make it again.
What does it smell like? Weird question, I know, but I'm curious.
Fish, probably.
Rusty tetanus 😉
The "right stuff".
Victory.
Except for the narrator, he needs to stop trying to be a rocket scientist and stick to his day job,a narrator. And NO, being 14KFt under the ocean had nothing to do with the level of destruction these poor engines experienced, explosive hydraulic deformation from impacting the ocean at 100's of feet per second, explosives could hardly of done more damage, such a crime to not to put parachutes on the aft end of the Saturn 5 SIC first stage, bring it down fwd/front first and let the tanks collapse and absorb 99.9% of the impacting energy. Very do-able but NASA didn't want any salvageable parts. Now they claim salvage rights, sorry it's international waters just like a ship wreak.
Ah, built when men where men with Pocket Protectors. Real Steely Eyed Missile Men.
furyIIIplate yes mate when men were men and sheep were nervous
Not from NZ are you? rob wells
rob wells o
AND SLIDERULES!!
furyIIIplate .Plymouth Fury 3,,,. Plymouth Fury! Now that was a car. Stock 460 would make the whole car tilt when you rev the engine at a stop light. And what a beauty. Man that car was great, my favorite car of all time. My Dad got one second hand from my great grandma when he was about 19. Think it was a 66. Then when I was in middle school my older brother bought a 73 Sport Fury. That thing was s beast. An absolute boat. Solid steel from bumper to bumper. He accidentally backed into another car, that was itself a good sized older car, and it punched a two foot hole in the other guys ride and literally barely scraped the dust off the chrome bumper. Bench seats front and back, could comfortably seat eight adults. We could fit another six in the trunk alone. Love those old Mopar mobiles. I miss metal cars. P
Probably similar in design to the rocket engine that Werner von Braun used in the V2 that he built for the Fuhrer.
Dear Geek Wire, thanks so much for this wonderful commentary
Will it fit in my Honda?
Guitarfollower22 dam dude I think VTEC seriously kicked in that time 👍🏻👍🏻👍🏻👍🏻
It will EAT your Honda.
Ive seen bigger fartcans on them
I actually thought there was a bug on my screen
This is an AMERICAN made F1 engine, so NO it won't fit in your japanese car.
You can see how much titanium was used as the corrosion is minimal 😮
Anyone else get a little depressed when they see Apollo artifacts knowing that you'll never get the chance to be a part of a program like that?
Well....i´m never going to walk on the Moon,but i can live with that.
Yes
Yes
Behold: Artemis, Dear Moon
@@dirtyharry1844 starship will make moon tourism a possibility for many. Its more like a reality nowdays that common people will go to space
"The Human Adventure is Just Beginning."
Star Trek theme starts...
It is or was a process called electrolysis that ate the material / alloys off theres F1 engines ! All ships deal with this by placing zinc blocks where water is agitated and still , it's basicly the same process as electroplating where a positive current passing to a negative this takes small amounts of material from the base metal and deposits it onto the surface you want coated / electroplated ! There are lots of new methods today using static , vacuum, heat and powder ect ect but it all basically does the same thing coats a surface with a material of your choice.
Merci & Bravo!! Monsieur Jeff Nun, for this well explained short video of;
What you have at hand as curator of the Seattle Museum of Flight.
Recovored from the bottom of the Atlantic ocean, in regards to APOLLO missions.
Speaking thru a {hahahah} GeekWire microphone.
Best/Kind Regards, and best of luck with your future exibits sir ...
Looking FWD to eventually, though i have my doughts, meeting ya ;)

If memory serves, the thrust chamber bells were hand brazed Inconel X-750 CRA material
They were brazed but they actually placed all the tubes onto a large circular holding fixture and put the entire assembly into a large oven. Once the parts were heated they sprayed the brazing material on as a liquid. Afterwards the tubes were pressurized with water to look for leaks. When they found them the leaks were touched up by hand to close them.
What a piece of machinery they are
Apollo 12 = second mission to the moon.
Where'd Apollo 8 go then?
Christopher Miller Around the moon.
second mission to land on the moon.
Robin Frischkopf Yes.
Apollo 8 was went to the moon. The spacecraft was within the gravity well of the body, so it was at the moon.
Don't forget Apollo 10. They came to within 10 nautical miles of landing. The lunar module wasn't ready to land yet and a test of the ascent stage of the LEM was needed. They had a couple of glitches with the Nav. CPU but managed to come home
Just 60 nautical miles.
just think what we can do today;when we did such a complex eng 50 years ago.
The whole Moon project was done on less than a 286 computer.
@@MEugeneDavis Indeed, and yet so diligent were the FIDO/GNC/RTCC/Orbital Mechanics guys, that most Apollo missions required only 1 or 2 very minor course correction burns all the way to the moon... brass gyroscopes, weighing many pounds, built fine as a Swiss watch... "T minus 15, Guidance is internal..." SALUTE!
It's sad that NASA struggles to make technology as good as this today.
Compared to the highly inefficient F-1 they have some magnificent engines that make the F-1 look primitive and ancient in comparison
The F-1 was a heavy engine but it was absolute trash in terms of effiecency. The SSME engine for the space shuttle and soon SLS are amazing engines doing double and close to triple the effiecency of the F-1. The F-1 wasn't even made by NASA but instead rocketdyne. Also there's the never heard of M-1 which was like an F-1 but better in every way.
nasa is only contractor they are not building rockets. There is proposal to use highly upgraded F1 on SLS by rocketdyne and pratt so who is strugling with anything?
NASA is a bloated bureaucracy of unionized government workers there for just a paycheck.
Yeah and these new amazing engines can't get past low earth orbit. Wake up your caught up thinking small. Give me primitive technology anyday, at least I know it works.
So can I go on Amazon and buy the thing? Does he have a good recommendation?
This engine produced over 30,000,000 horsepower.
1.5 million of lbs of thrust coming out which end again? You don't say coming out of the exhaust end... man this guy is good
8,000 pounds of fuel per second, per engine, x5 = 40,000 pounds of fuel per second for 2 minutes!
Incredible flow rates, temperatures and pressures!
Quite interesting .
No turbopump in the collection?
The corrosion would happen more like how a lead acid battery works rather than accelerated rusting from salted roads.
Those numbers did not look etched into or stencilled onto the metal...
3:13 “...this really incredible weld material...”
Lol, oh you “metal”. It’s called *metal* ...
I still wear pocket protectors. Saves a lot of shirts as well as carries a 6 in. Starret rule.
I am building one of these for my Honda.
Methinks this was Stewy from Family Guy doing the voice over for the presenter
Could someone tell me why the F1 does not seem to have a converging section and throat?
Oh, they did, for sure. This video isn't a great view of a full up engine.
The metal at 2:30 min looks more like consumed by bacteria or archaea than corroded by salt water! These patterns look organic.
The same things that eat Titanic
No shit, Sherlock. Whatever would we do without YOU to tell us it was microbially induced corrosion?
Looks kinda clean to have been on the bottom of the ocean.
They probably cleaned it.
Yup.Just what I thought. But I suspect a lot of the trick alloys used in the construction were corrosion -resistant.
"bell like nozzles" = thrust chambers.
Uh, no. They are NOT the same thing.
I expect the impact with the water was alot harder than the impact with the sea floor?
Now of only Bezos could get rocket parts into orbit rather than collecting old ones off the bottom of the sea...
Hats off to Jeff Bezos for preserving this important bit of history.
When America built stuff..
didn't one of the other stages have an F-1? that would mean more than 5 on each Saturn 5
The second & third stages used J-2 engines.
To despite what both space program Russian and USA has common initial, rocket engines look absolutely difference , burning chamber , nozzle
Yes. And acted different. Ours delivered us to the Moon!!!
Awesome
Not sure you want to mount an Apollo 16 heat exchanger with an Apollo 12 thrust chamber. You should keep missions separate.
You know when I was with Rockwell Space Division Downey Speakers Bureau we had to know exactly what we were talking about. For being a curator for this museum he sure has his facts off and stumbling over him self . god I hope he does not give public talks. How can you describe hardware when you don't even know their names.
You know, I was driving by the building my father worked in building the F-1. The J2 and H1 were in buildings nearby.
Why doesn't Canoga Park put monuments in front of these facilities? You would think they would raise a lot of civic pride that all the engines for the Saturn 5 were built in their city.
Um, umm, uhh, ummmmmm, uhhh....
Is Jeff aware that he has one of the best jobs in America?
Great Explanation. Seemed a bit nervous, but still great info.
Those turbines pumped 2.5 tons of propellant a second.
this is wonderful, but really, a 2:30 min commercial? there are many other videos.
AdBlockPlus. Haven't seen a commercial on RUclips in a few years.

I wish the museum was in a city that didn't have actual shit on the sidewalks because this would be a great display to view. As much as I would love to see it in person, I'll pass.
I THINK HE SHOULD WATCH MORE SCOTT MANLEY, SO U CAN AT LEAST SOUND LIKE U KNOW WHAT UR TALKING ABOUT.
"A million and a half"... 1,000,000.25 lbf != 1,522,000 lbf.
yeah that's 3 raptors engines to equal 1 f-1 :) that's some serious lift buddy
That's a million and a quarter, buddy.
More engine, less face
My dad died buidling one of these engines hit right in the head with a giant screw or nut
Americans think that injector plate should be classified information.
Still, you don't see weld jobs like that on any rocket engine nowaday.
No wonder NASA now uses solid fuel boosters.
Isukaman , The Shuttle's own 3 main engines were also liquid fueled like this one.
They used solid rocket boosters because they're cheap. Came back to bite them on Challenger… oops. Space Shuttle is a crap heap, 40% vehicle loss rate. Apollo missions were the golden years.
150 launches, 2 losses. There's nothing too wrong with that record.
MattOGormanSmith It was 135 launches, and that failure rate is atrocious! It's designed flight failure rate was supposed to be 1 per 100,000 launches, so instead of 0.001% it was 1.5%. The Space Shuttle killed more people than any other spacecraft in history (by far). If you divide project cost by flights it comes out to $1.3 billion per launch, so it's also the least cost efficient booster ever used. By almost every measure possible it takes the cake for being history's most expensive, most dangerous, and most unreliable manned spacecraft ever built. Even former NASA administrator Michael Griffin called it “a mistake.”
Michael Pendergrass I never claimed the engineers _believed_ that figure, but that's what was claimed by NASA officials to the public and politicians alike. Just adds to the deceptive nature of the program and the unrealistic mindset that brought it to life.
I think anyone with sufficient experience would laugh at a figure like that out of hand when talking about a rocket booster, that level of reliability simply isn't feasible.
turb-EYE-n -> turb-in
Интересно из чего трубки на сопле ?непохоже что из меди.
Sorry the Saturn 5 f1 engines were 18 feet long and 12 feet in diameter..that engine looks small
It's missing the engine bell, that's all.
Cool
