Saturn V F1 engine questions

Saturn V questions - why black exhaust for first 8 feet?
It is rocket engine or flamethrower?
How did they really solve the combustion problems with THAT large rocket engine?

What a bunch of garbage. The "mysterious" black exhaust is only the result of the kerosene-rich mixture used to protect the engine bell. This is done by running the injectors around the circumference of the injector plate "rich', thereby creating a (relatively) cool boundary layer around the exhaust plume. Amazingly, a smoky flame results! (more)

The view of the F-1 engine at 1:15 shows the turbine exhaust manifold wrapped around the outside of the nozzle extension, and inside are the injectors that set up the film of turbine exhaust gas that cooled the nozzle and produced that dark zone in the exhaust.

I don't know this Wood character, but it sounds like he heard bits and pieces of the real story and glued them together in a pretty nonsensical way. If he's a "propulsion engineer" he certainly isn't a competent one.

@loxengine

Probably because they are more efficient although not as powerful. Probably cheaper too and money talks.

If F-1 was so good, why USA don't use it now? Why import russian RD-180 and NK-33?

RIP Kaysing you idiot!

@occhamite Thank God I am not alone in knowing about the development of the F-1 Engine. Thanks for your input. g6ypk rocket buff. (nerd)

@incargeek True that !

[incargeek]

No no no!! The black region is fuel rich exhaust from the turbopumps. The nozzle extension does not have active cooling so the turbo pump exhaust (which is relatively cool black and sooty) is ejected from a manifold that runs around the perimeter of the nozzle. The fuel rich exhaust flows into the boundary between the hot exhaust from the main combustion chamber and the inside of the nozzle extension, keeping it cool.

So if the f1 was crap. Then why dress up a smaller one to make it look like the f1 when weight (or the lack of it) is absolutely critical?

The darker flame front is the result of ventury effect common when using thinned kerosene/parafin and lox. Especially when using such a large combustion chamber.

This is the most retarded video I have seen

@disorganizedorg Well, Kaysing may have been right that combustion instability was a problem right up to the end. Right up to the end of his employment with Rocketdyne in 1963, four years before the Saturn V flew for the first time. A *lot* happened during four years in the midst of the Apollo program.

@GetOverHere83 As opposed to a "genius", e.g., Richard Feynmann -- someone who could explain something complicated in a way that almost anyone could understand and even think it was simple.

Anyone who claims to actually understand Kaysing and Wood here is simply lying.
