I proud you as my teacher said to me! | Hi Steve, For those that know me I have a little library of books and manuals. The drawning above came from a Bf-109 manual. The big thing when posting pictures is to size them properly for the forum but also make the legible to read. I have multiple programs for that Adobe Paint, Corel but by far the one I use the most it the paint program that comes with windows XP.

You will need a scanner to do that. If you post a small article try and name the books title and auther. One think I seem to be bad about doing.  If you are talking about the Adobe documents then you need adobe acrobat to create these type of documents. Hope that helps.
By the way its a very small library. Maybe 600 books on various subjects from tanks, ships and aircraft. Not including my aircraft manuals. Most of the books are Hardcover, soft covered and in pdf format.

I think what xtberia was getting at was how a weapon could fire through a crankshaft. The simple answer was it didn't, it fired through the reduction gear, not the actual engine. The barrel/blast tube usually went above/below the engine between the valve banks, and exited through the reduction gear, which was connected to the actual driveshaft.

Country: | Sorry folks, I am a bit late in responding to your prompt replies. With very vivid details too, I might add. Many thanks to Micdrow, Graeme and Steven Que.
Thanks too, to Stitch, for an insight as to how a gun would have fired through the propellor hub. However, without a picture or a drawing to aid in understanding how a reduction gear could have facilitated the entire arrangement, it becomes slightly difficult to comprehend.
In any case, what I was actually trying to figure out as to how the machine guns could have been synchronized to fire through the propellor without hitting the blades, in the process. [For a more clearer understanding of my question, please could you refer to the Bf109 drawing as posted by Micdrow.] | |

Country:  | Hi Xtberia,
>In any case, what I was actually trying to figure out as to how the machine guns could have been synchronized to fire through the propellor without hitting the blades, in the process. Interrupter gear - Wikipedia, the free encyclopedia
Note that typically for Wikipedia articles, it features some good stuff (the diagram of a WW1 era interrupter gear) mixed with some deliberate spin-doctoring.
("German and Soviet fighter types in particular were slow to abandon fuselage-mounted guns" - the truth is that everyone else "was slow to" adopt electrical synchronization that made synchronization rock. Naturally every air force wanted their guns as close to the centreline as possible to do away with convergence/divergence issues, it's just that it was a technological challenge to develop a reliable, fast-firing, high-firepower, synchronization-compatible gun that would fit neatly into the nose or wing roots of an aircraft.)
Regards,
