One of the best Saturn V video clips I've seen. (If there were that much snow coming off a Shuttle at launch there'd be a hundred and seventy-five heart attacks in mission control. The video is awe-inspiring and depressing at the same time. )

Beautiful, simply beautiful.

Thank you for posting that, it's made my day.

As an aside, you wouldn't have any idea who sings the song playing in that clip? It's very good!

cheers

Wat for fantastic Video ;D

must be Launch SA-510 or SA-511

most of film during flight was made by several Cameras in S-II stage
they install in a return capsule, in Interstage between S-II and S-IVB
by use of Mirrows and Fiberoptic they taped the engine bay, LH2 & Lox tanks,
and the Interstage during separation of S-IC And S-IVB

You see in last second of video how the S-II make roll towards earth
and jettison the return capsule while the Camera still is running !

by the way has some one, the video of LH2 & Lox tanks on those test launches ?

Couldn't agree more! One thing I'd never noticed before was how the rocket lifts up through its own vapor cloud in the first few seconds after launch. Another thing that is always surprising to me is the dark color of the F-1 exhaust for the first couple of meters out of the nozzle. Is that RP-1 leftover from film cooling the nozzle?

I believe only the earliest flights carried camera pods. I suspect we're looking at AS-501.

The sequence showing the S-IVB igniting is actually from a Saturn IB flight--probably AS-201. One of the ways you can tell it's a IB and not a V is that there are three ullage motors on the S-IVB.

Have you seen this thread:

http://forum.nasaspaceflight.com/index.php?topic=14796.0


on the NASA Spaceflight forum? It shows internal views on a Saturn I flight.

There are still a couple of views I'd love to see, but to my knowledge they were never filmed:

  • View from an S-IV or S-IVB of an S-I or S-IB falling away, and
  • View from an S-IC of an S-II igniting and pulling away.

OH MY GOD !
Wat for a Video

[flash=200,200]http://www.youtube.com/watch?v=_dkxDx6RiM4&eurl=http://forum.nasaspaceflight.com/index.php?topic=14796.0&feature=player_embedded[/flash]


the First tanks is from Saturn-I
that's must be the central Lox tank,
That strange structure in center of tank is to prevend that Lox swashes heavy around in Tank

Beautyfull the stage separation
the little flash are pyro technical bolds and cutters

At 2:19, the second Tank is the LH2 tank of S-IV

The sequence showing the S-IVB igniting is actually from a Saturn IB flight--probably AS-201.
thanks for the info

on two first Saturn-V had camera pods.

...The slosh tests reminds me once again - and both Scotts have heard this one before - of one of my visual "Holy Grails". When the Saturn I slosh problems were being researched, one of the early slosh baffle solutions was to dump several dozen beer cans into the tanks. The reason for wanting to see the video was to attempt to see which breweries contributed to the space program in this unique and important way.

"This Saturn I launch is brought to you by Budweiser...literally!" ;D

According to the site: Stina Nordenstam - 'Ask the Mountains'.
Thanks,

I guess it helps when you bother to read the info on the site.... ::) apologies for that, me dumb...

If you're feeling dumb, I can top that: In my previous post in this thread, I say

Well, the very clip that I posted shows the S-I falling away from the S-IV. I guess it helps when you bother to look at your own post! :-[

Hello!

From the NASA forum

Outstanding S-IC/ S-II staging video.

I've just got around to watching it.

Bloody amazing!

I wonder if any of the more knowledgeable forumers could explain the little streams of gas that appear early in the launch, snaking diagonally down the body of the launcher?

I presume you mean at around 39 seconds into the video (and again at 2:12)? That's water vapor. The little ports there are, I believe, oxygen vents. The LOX in the tank would heat up in the Florida sun and would want to boil; it's best to let it do so, and just give the gas somewhere to go before it overpressurizes the tank and blows it up. So it's dumped overboard.

Anybody who has ever been at Cape Canaveral in the summer is hit with one impression: heat & humidity. So when that very, very cold oxygen hits the air, the water vapor immediately condenses out, making clouds. As to diagonal: there are two vectors, sideways and downwards:
Sideways: there is a breeze, blowing it sideways.
Downwards: two forces. One is the fact that the rocket itself is moving up, while the cloud isn't. If you look at the later video (at, say, 2:20) and watch individual puffs of cloud, they go sideways, but don;t really go down much at all. But the rocket itself goes up. The second force, which would really only be in play very early in launch, is the ejector effect. The exhaust from the F-1 engines would grab onto the surrounding air and yank it aft; this would leave a hole in the air excpet for the fac tthat more air moves in to fill it, and is then also grabbed by the exhaust, etc. The result is that even if the rocket is locked down and immobile, it sets up a downwards "wind" in the vicinity.

Cheers! I thought it was venting of some kind.

I was just adding the 'diagonal' as a descriptor - but I'm glad I wasn't clear on that in my mail as I hadn't heard of the 'ejector effect' (unless is is similar to 'entraining').

Does the ejector effect also account for the initial combustion smoke from the F1s getting 'sucked' down into the flame trench after about a second (film time) of explosive expansion at the start? That phenomenon always puzzled me in all the Saturn V clips I've seen it in.

Thanks

Yup. When the rockets first fire up there is an increase in local pressure, but as the exhaust streams build and stabilize they get the ejector effect up and running.

You know who else used the ejector effect?

Amazing footage, also like the one with the view inside the tank - that's the first time I've seen this kind of thing!

...There's one clip I've been looking for for years, but apparently it's never been widely circulated. During the early fuel flow tests of "Cluster's Last Stand" - the Saturn I - the engineers came up with a rather unique solution for fuel sloshing. They threw a bunch of beer cans into the tanks, and they acted as perfect slosh baffles. What's been of some curiosity is just which brands of beer the engineers chose for the baffle tests, and the video taken from inside the tanking tests could show enough of the cans to determine this.

They had a camera looking toward the S-II stage from the forward skirt area of the S-IC at the same time, but unfortunately either the camera pod didn't jettison properly, malfunctioned and crashed into the sea either alone or with the S-IC stage, or was never recovered. Some of the camera pods malfunctioned or were never recovered... I remember reading at least one was recovered one time a few weeks after the launch, after it had survived being blown/washed away to a completely different area by a hurricane shortly after the launch... Think they found it washed up on a beach in the Bahamas or something IIRC...

I also read they DID shoot some film from inside the propellant tanks, but I don't think that film survived or else has never been released. There's footage from inside the Saturn S-IB first stage on the Saturn I Block II, along with footage from inside the LH2 tank of the S-IV stage and S-IVB IIRC... that footage is on the DVD's "The Mighty Saturns" from SpaceCraft Films...

Later! OL JR :)

...That footage was floating - no pun intended - around for a while before SCF got ahold of it and cleaned it up. The footage that still evades Saturn researchers and enthusiasts is that taken when they did the "Beer Can" tests, where a bunch of beer cans were used for slosh baffling. The results were very successful, but the question that's never been answered is just what brand(s) of beer the engineers used for the test.

The Davidson Center in Huntsville has a very nice set of displays on the F-1 engine testing that took place at nearby Marshall.

Very impressive. Both the video, and the fact it actually sounds good [1]. From the delay I'd say the microphone was 1.5 km away.


1: unlike lots of rocket videos where the sound is either clipped because the microphone can't handle the volume, or YouTube compresses it all to hell.
