F-1 Engine Cut-Aways
I've collected a number of F-1 rocket engine cut-away diagrams for this page. I was originally going to use these diagrams as a take-off point to discuss various features of the engine, but the resulting page wound up being huge. I will, therefore, refer to you to my F-1 thrust chamber, F-1 injector, and F-1 injector baffles pages. All that remains on this page are several gratuitous F-1 rocket engine cut-away diagrams.
For a detailed description of the combustion chamber, as well as many fabrication/assembly photos, see my F-1 engine thrust chamber page.
This cut-away diagram depicting the F-1 injector end, as is typical of color diagrams of rocket engine internals, represents LOX flow as green and fuel flow as red:
This diagram, from a paper which seems to date from sometime before July 1967, shows another view of the injector. I'm not certain why this diagram lacks a number of features of the other injector cut-aways; my best guess is that this particular diagram was unclassified back in the day, while the other diagrams were still classified at the time. This diagram does give a better feel for the LOX flow.
This final injector cut-away diagram clearly shows how the radial injector baffles are regeneratively cooled, with the feed line leading from the fuel feed passage, through the radial baffles, and finally to the radial baffles themselves:
