Here's a little bit of a change for me... I've spent a couple days reading this study, trying to figure out how best to summarize it, and pretty much figured out that I can't really summarize it and still do it justice-- there's SO much good information in there that deciding what to cut is rather pointless... it'd just water the whole thing down too much.

SO, after debating what to do, I decided to just post the entire thing. Of course it won't fit within the file limits of the site, but that's okay, since it's on the internet already... here's a link to the study...

https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19740021163.pdf

Of course a study summary wouldn't be much use without the usual snips of the various pictures, diagrams, blueprints, and graphics... and there's a bunch of them, which will be in the posts to follow.

Basically, if there's ANYTHING you ever wanted to know about the Saturn IB, specifically the ones used for launching the Skylab crews, which represented pretty much the height of Saturn IB, then this is the thing to read. Everything from abort modes, the positions of pretty much every switch and button in the capsule and how to use them, and what they do, how the range safety system works and destroys the vehicle if the button was pushed, the events of the flight, how the engines started up, etc., it's all pretty much in there.

SO, download the study, read to your hearts content, or just peruse the snips I'll post shortly. It's pretty amazing history of a very interesting vehicle, which sadly never even approached it's full potential... and it was done on the cheap on fairly short notice, and the very dawn of the space age...

Pics to come... Enjoy! OL JR :)
 
First, basic "station numbers" (dimensions) of Saturn IB
aaSIBFM.jpg

Next, the PLANNED Skylab mission profile... two things of interest here compared to how Skylab actually flew-- first, the original plan here called for a 28 day mission first, followed by TWO 56 day missions-- no mention of an 84 day mission at all. Also note the missions were to overlap slightly, with no unmanned period between launches. Of course the emergency repairs that had to be worked out for Skylab before the first crew could launch couldn't be accounted for either...

Well, that's it... of course I didn't copy EVERYTHING... there's literally TONS of data in there relating to the operation and functioning of the Saturn IB that was a little too "arcane" to bother putting here... but it's in the study...

Enjoy! OL JR :)
 
Luke,
this is a GREAT post! I actually bought this book off of Amazon last year and if you are a Saturn 1b buff, I would recommend it. It literally covers everything with the operation the rocket! Its a great resource. Of course, my copy clearly states its the Saturn 1b flight manual and it has a big picture of a Saturn V on the cover....swing and a miss there by the publisher!

Well, most publishers wouldn't know a Saturn V from a Black Brant... If you REALLY want to read a stinker, get "Rocket Men" by Craig Nelson... that thing is SO full of errors that even an amateur like me can find fistfuls of... Don't buy the thing-- get it from the library. I swear the thing must have been edited by a chimp... I bet the Craig Nelson that played "Coach" on TV knows more about the space program than this guy...

Anyway, ya coulda saved yer money... LOL:) Nah, I'm like you... I'd like hardcopy if I can get it...

Later! OL JR :)
 
it is a great reference book!
I recently picked up some old publications I found on Amazon...they are Saturn 1b launch vehicle flight evaluation reports...basically the Saturn engineers post flight analysis if the performance of the rocket...in detail! I got the ones for the Skylab missions...each 1b that flew. neat stuff!

Hmmm.... wonder if they're on NARTS?? I'd love to see those...

Got specific titles and dates??

here is a picture of the books.....they are old obviously but its interesting to read how they analyze the performance of the rockets....

Great posting, Luke.


Here's a web page I have for the Saturn-IB. Mainly a detailed drawing I did, converted to 1/70 scale to match the Apogee/Estes/Semroc kits. Also a 1/35 version so it can be printed at 50% to get better printed detail at 1/70 size than printing the actual 1/70 drawing.

Plus some pics of the Saturn-IB on display in Alabama.

George...thank you for making that detailed drawing...you have no idea how often I have used that with my builds! thank you!!:cheers:

Thanks George... I appreciate the kind words. Hope folks get some use from this sort of information.
GREAT work on the drawings and stuff BTW...

@ Rick... I think I found them on NARTS... Did some searching on there yesterday and downloaded them to my hard drive, but I didn't really have much time to read them... yet. Didn't see much in the way of graphics or anything in there, but I'm sure the data itself is most interesting...

Later! OL JR :)
 
Hi Luke,
the data in these books is fascinating,...most of the illustrations are graphs and charts...but they evaluate pretty much every major system, guidance, hydraulics, battery performance, guidance, trajectory, engine performance....just really interesting stuff.
Luke, your posts are always appreciated....you have posted a lot of really interesting publications and articles and everything!
