Sneak Preview: Recovered Apollo Saturn V F-1 rocket engines at the Museum of Flight

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.

[@michaeldavis9774]

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!

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.

[@Patchuchan]

True and the S-IC probably impacted with the ocean engines first as that's how it would orientate itself during free fall.

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.

[@TheSkiddey]

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.

[@Alexagrigorieff]

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.

[@Damien.D]

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.

[@66lesjo]

Alexagrigorieff You are probably right but do you think that maybe certain areas were buried in silt and protected from corrosion to some degree?

[@Damien.D]

I thought so at first but it's obviously (look at 5:42 ) only one panel that precisely had rusted.

[@66lesjo]

I see your point, its just that one panel. It must have been the Friday afternoon shift at the foundry.

[@MattOGormanSmith]

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

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.

[@jhmorris3486]

If memory serves, the thrust chamber bells were hand brazed Inconel X-750 CRA material

[@joevignolor4u949]

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.

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.

[@PaulHigginbothamSr]

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.

[@rohesilmnelohe]

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.

Those turbines pumped 2.5 tons of propellant a second.

My dad died buidling one of these engines hit right in the head with a giant screw or nut

No wonder NASA now uses solid fuel boosters.

[@massimookissed1023]

Isukaman , The Shuttle's own 3 main engines were also liquid fueled like this one.

[@mrjpb23]

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.

[@MattOGormanSmith]

150 launches, 2 losses. There's nothing too wrong with that record.

[@mrjpb23]

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.”

[@mrjpb23]

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.

[@mattc9364]

Still, you don't see weld jobs like that on any rocket engine nowaday.

Hats off to Jeff Bezos for preserving this important bit of history.

[@c1bav]

one question ? will it fly again? lol

[@DarkSim77]

When America built stuff..
