Saturn V - "F1" engine static fire test (full stereo sound!)

Rocketdyne actually proposed building a modern rendition of the F-1, or the F-1B for SLS as a workhorse for a Liquid Rocket Booster. It would’ve resembled an upscaled SpaceX Merlin-1D if built. Unfortunately, this didn’t get off the ground as the SLS evolution plan changed.

3 tons of fuel per engine, per second wasn't it?

[@andystevenson5067]

That’s INSANE

[@joevignolor4u949]

@@ZilogBob The number is correct but it's actually about 3 tons of propellant, not just fuel. A single F-1 burned 5,683 pounds (2,578 kg) of oxidizer and fuel per second. (3,945 lb (1,789 kg) of liquid oxygen and 1,738 lb (788 kg) of RP-1 Fuel). The engine accelerated that amount of propellent through the nozzle going from O mph to 1,000 mph between the injector plate and the open end of the engine bell, a distance of only 18.5 feet. Accelerating that amount of mass to that velocity produced 1.5 million lbs of thrust.

[@ZilogBob]

@@joevignolor4u949 I always assumed that the oxidiser is considered to be one component of the fuel. It's all in the definitions.

[@joevignolor4u949]

The proper term is propellant pumps. Even NASA gets this wrong. They called the space shuttle's propellant tank the "external fuel tank", but that term is not accurate. If the external tank was only carrying fuel, the shuttle would never have gone anywhere.

[@Zacharysharkhazard]

the Saturn V was honestly an engineering masterpiece of it’s era. They pushed technological and material boundaries to their very limits, and made a vehicle that has taken *50 years* to be shown up.

[@MrGruffteddybear]

@@Zacharysharkhazard I remember some dialogue in the miniseries From the Earth to the Moon when James Webb is asking if we can achieve President Kennedy’s directive, and the answer was, “We’ll need thousands of people, special facilities, technology and material that haven’t been invented yet.” Webb asks again, “Can we do it?” And the answer was, “Yes. Absolutely. We have to.” I am still amazed at how all the pieces came together in a relatively short amount of time. Kudos to all who worked on the Mercury, Gemini and Apollo programs. 😊

[@ryelor123]

What beautiful engines. I don't care how efficient staged combustion engines are, the F1s were all custom-tuned works of powerful art. A metaphor for the post-war optimism that was murdered by the 1970s.

I think this is on a test stand. The Saturn V had the four outer engines gimble with the center engine fixed. You could get by (maybe) with only a center engine gimble, but then you have to have additional roll control.

I don't like the "Starship" project. The first flight wasn't a real success at all. It has been a very dangerous testflight and it was a completely stupid idea to launch such a big and powerful rocket without a necessary flame trench and especially without a big sound suppression water system! And by the way, Mars shouldn't be the goal for human settlement for many reasons! Maybe Mr. Musk isn't the smart guy he wants to be... I have my doubt's about him.

[@uranus5213]

What is the black gas coming out from the Engines? Is the exhaust pumped in the nozzle extension as Ablator or smth?

[@thebackyardspaceprogram]

The engines have a gas generator that powers the pump and since it generates excess gas, it goes around the nozzle in the manifold and it cools it. So that black gas is actually gas generator gas for nozzle cooling!

[@jimmcmahon217]

The gas generator ran fuel-rich, thus it's exhaust was relatively cool and sooty black. As it "cooled" (a relative term) the nozzle walls, it mixed with the main exhaust which completed it's combustion.

[@guitarshredddddder91]

Ya like going fast kid? Get in.

[@TasmanianTigerGrrr]

That dark band of gas that hasnt fully ignited is moving crazy fast just below the nozzle

[@peterjensen6844]

That's not gas that hasn't ignited. That's the turbine pump exhaust that's dumped in around the inner edge of the bell housing. It's cooler so less heat risk to the bell.

[@ryelor123]

That's soot. They ran extra rich. I don't remember the reason but I think it was to keep them from burning up.

[@fromnorway643]

@@ryelor123 The gas generators powering the turbopumps ran very fuel rich to keep the temperature low enough to avoid melting the turbines. That exhaust was then used to cool the outer part of the nozzles and also added 18-20,000 pounds of extra thrust to each engine's 1.5 million.

@@ATINKERER sorry yes you are right, because it's just the injector plate and then the nozzle. my guess would be that even if it isn't a traditional 'de Laval' nozzle, there is still an expansion ration as the engine widens, which should generate the thrust required

[@ATINKERER]

@@shreyas7336 I had the same thought. Maybe they were pumping in so much fuel that the flow went supersonic leaving the combustion chamber. Otherwise the expansion section would be useless in a subsonic flow. It just seems odd to me, and I'd like an informed explanation.
