F-1 in Huntsville!

My first F-1 post!

Two of the Brickmuppet's Crack Team of Science Babes report that Huntsville Alabama is home to the first F-1 test and quals since 1969 and the first F-1 ever since 1973!

Wait....

"Science Babes Moonlighting as Race Queens" is not the actual title of this piece by Tan-Tan.

If Formula One hasn't existed since 1973 what's this guy going on about?

"What?..."

"Oh!..."

The Science Babes are at their other job in Les Mans, which caused my confusion as they're actually talking about...

The Rocketdyne F-1 rocket engine!

The huge engines that powered the first stage of the Saturn 5 rocket which put 12 men on the moon and Skylab into orbit hasn't been built in 44 years. Contrary to popular belief the plans for these beast DO still exist, but they are in obsolete computer formats and of limited use.
You see, the Apollo program was so rushed that a lot of the little 'tweaks' that were found necessary to keep the rocket from failing. This was not fully appreciated until the '80s when NASA and USAF engineers noted that there were holes drilled and pieces added to some of the F-1s in museums...holes and fiddly bits that weren't on the plans. The engines were exploding during tests and the production crew did some trial and error modifications until the "splodies" stopped. Additional tweaks were added at the plant to facilitate production, so the F-1 plans are actually plans for an inefficient kerosene/LOX bomb.

Well, engineers in Huntsville have taken apart and are restoring some of these engines, which were discovered to be in remarkably good shape. This time making a note of Every.Single.Part. And. Hole. The plan is to do a computer model of the engine that is accurate, but they need to ensure that they are building it from a working engine...so.....



That's just a test of the engines gas generator from last year...
This project is the brainchild of Marshall Spaceflight center engineers who felt that they ought to DO something with the dozen or so F-1s lying around the research center. They've been calling in other rocketry companies to observe and consult. In addition they've been bringing in the few surviving Apollo engineers to work on this interesting side project...which has resulted in a tentative design and proposal for the F-1B 



 This is not as silly as it sounds. One of the things about the F-1 that was discovered back in the 60's was that, due to its very conservative design it was actually pretty re-useable and it was felt it could be made completely so with a few tweaks. F-1s were considered for several early space shuttle designs propelling reusable flyback boosters.



 The mighty F-1 may yet again spew pillars of fire for the chariots of explorers.
