Great post, thanks.

If memory serves those five F-1s were very thirsty, They burned fifteen tons of propellants per second, developing seven and a half million pounds of thrust, one hundred sixty million horsepower. I can’t comprehend why they didn’t collapse under all that pressure. In fact, the entire Apollo program still impresses me. Also impressive is the fact that all twelve men who walked on the moon were Americans.

all twelve men who walked on the moon were Americans.

White males, I hope you're showing the appropriate guilt over this stunning lack of diversity.....

It’s one of these very engines.

That Saturn V was an amazing machine. You’re right, the numbers are mindboggling. The Sov’s gave up trying to build anything that powerful.

From the Wikipedia:

The F-1 burned 3,945 pounds (1,789 kg) of liquid oxygen and 1,738 pounds (788 kg) of RP-1 each second, generating 1,500,000 pounds-force (6.7 MN) of thrust. This equated to a flow rate of 413.5 US gallons (1,565 l) of LOX and 257.9 US gallons (976 l) RP-1 per second. During their two and a half minutes of operation, the five F-1s propelled the Saturn V vehicle to a height of 42 miles (68 km) and a speed of 6,164 miles per hour (9,920 km/h). The combined propellant flow rate of the five F-1s in the Saturn V was 3,357 US gallons (12,710 l) per second.^[5] Each F-1 engine had more thrust than three Space Shuttle Main Engines combined.^[6]

hey, star trek got us out of white guilt about space.

I've been on an Apollo kick myself for the last week or so. Watching everything I could on YouTube from that time. Here's the video that got me started.

That was such a wonderful time for me, as an American teenager (the summer between eighth and ninth grade). Listening to these conversations brings so much of it back.

One thing I noticed: the hum. In all the audio recordings of Apollo-Houston conversations, there's a deep, ever-present hum that's not quite at the limit of audibility.

What struck me is that you would never hear that hum today; the reason is because all communications channels - including voice - would be digital in our time. Back then, they were analog. When you remember that it was often the case that Earth-crew communications were carried out via a huge dish antenna located somewhere other than in the continental US (I believe one such station was located in Woomera Australia) it is all the more amazing. Analog transmissions, over thousands of terrestrial miles. With so little hum.

This was more than a decade before NASA's TDRSS (digital) satellite system was put in orbit.

Badass!

PLEASE put this on display.

I'd love to see it.

At one time, man decided to see just how far their reach could extend. And they stepped on the moon.

Because they were actually just five second stage J-2 engines in an identical configuration, just with big nozzles.

After all, the thing only had to get to orbit.

Rocketdyne turbopump for Saturn V F-1 engine. Turbine, fuel pump and oxidizer pump all on a single shaft. Engine bearings cooled by fuel. Oxidizer pump: 24,811 gpm. Fuel pump: 15,741 gpm. Turbine generated 55,000 brake horsepower. Turbine inlet gas was 1,500F; Oxidizer pump inlet -300F. Mass flow to turbine: 170 lb/sec. Fuel pressure at injector face: 1,150 psi.

Thanks colorado tanker and KoRn, *another* extra to APoD members.

Been years since I read about it, but they had problems feeding the fuel smoothly to the engine. Needed some sort of diffusing spray or such. What they ended up with was the size of a manhole cover with lots of holes punched in it.

Mind boggling. Rockedyne used to have a dummy sitting out front of their San Fernando plant in the seventies.

My Strengths of Materials Professor in college was the structural engineer team leader on the stage 1 of Saturn 5. He would never actually admit it but we ran the numbers and yes it is a great feat that the engines never tore the thing apart.

"Each F-1 engine had more thrust than three Space Shuttle Main Engines combined."

As the saying goes: There is the money quote...........
