Saturn V first stage test firing

CaptainCrash · 31 Jan 2013 at 12:28

I don't often post in here, but thought I'd share this for anyone who's interested in such things and hasn't seen it before... it has Dolby 5.1 sound, so if you have a decent sound system (large subwoofer is highly recommended), turn the volume up and enjoy.

The five F1 engines together produced 7.5 million lbs of thrust, making it still the most powerful rocket ever built... by comparison, the four engines on a Boeing 747 produce a measly 240,000 lbs total thrust on full throttle.

Found it in an article at ExtremeTech

Fascinating.

Surely fake, look at the shadows!

I've already seen it, but great stuff, they are firing them and analysing them with modern equipment and at beyond Saturn V limits.

where's groan? he probably thinks its fake.

Strangely hypnotic.

Nice seeing it again.

Gotta love some of the awesome toys people come up with

@12 minutes reminds me what im like after a vindaloo! leaves the toilet humming.

Sure is !! But where in the world would you need to go that requires 7.5 Million lbs of thrust!!!, I mean, it's not like your trying to get to the moon or anything

Don't de-rail this thread, I genuinely do find it fascinating.

Incidentally, why did they stop using Saturn V?

I'm not, just saying 3000 tons of fuel not many other places you would wanna go.

Check this video also, its just awesome, chatter from the crews as it was flying, especially like the bit where the crew is saying 3..3.5....4G as it accelerates and then say something like HOLY *%^%$ Jeezus as the 1st stage cuts out.... so good

As for when they stopped using it, a FULL STACK Saturn V was apollo 17 I THINK, and then they flew modded versions of the 1st stage booster to launch skylab (which replaced the 3rd + command module + LEM container) and a cut stage version of it in 1975 for the apollo + soyuz meet up in orbit (this replaced the LEM with the docking adaptor for the 2 craft)

And thats it I think

.............such a shame such an amazing rocket it really had a soul in many ways, so advanced for the time, so brilliant, it really is rocket perfection, even though the new stuff is coming from NASA in the next few years, it STILL won't be quite as powerful, although similar, still though, there will never again be IMO a rocket that's just as amazing as the S-V......I genuinely think we will have found new propulsion tech by them time something as majestic as it will be needed again.

It was designed for one mission and that ended. It's far to powerful and costly for what nasa has been doing in the following decades, which has been focused on scientific reserch, which is best left and cheaper to non manned flight.
Space launch system is saturns replacment, which iirc is scheduled for 2017. With tests of parts in the coming years.

They were going to use it for the shuttle from memory, but they decided on the SRB/Orange tank combo instead

If its filmed in 5.1 I assume their nothing to play that back on Youtube right?

alexthecheese · 31 Jan 2013 at 14:29

That is seriously cool, in a way that I can't put into words. Immense.

Why are primitive rockets still being used (technology invented in 800AD) ?

Nuclear powered ion propulsion should have replaced it decades ago.

That's no use for getting into orbit though, not enough power to weight ratio at sea level.

Reaching orbit is trivial compared to reaching Mars in under a week or interstellar travel.

With enough resources it should be possible to build nuclear craft that are so powerful only the human body limits the maximum acceleration at 10G.

Have a quick search on youtube for something like 'Saturn V launch slowed down', or similar. Absolutely astonishing, 36 seconds slowed down to 9 minutes; when the rocket clears the blast pit, its only then you realise just how fast flames and fuel are getting chucked down through those thrusters.
