German Props in World War Two 3 vs. 4 blade

In this video we cover two main topics, German constant speed propellers and the question of 3 vs. 4 blade props. We check out some NACA reports, get a bit into some Glenn Curtis stuff, Guggenheim and more.

You may want to check out the previous videos in this series. There are two of them:

This video should stand on it's own assuming you have some knowledge of constant speed props, if not, you may want to watch those other two first or there is a risk this one won't make sense.

Be sure to visit the Sheriff to see his explanation of how manual pitch control is used in a 109F. https://youtu.be/lYQ8zWn2oZw His whole channel is great, if you like WW2 sim action, it's for you.

Updates:
I should have pointed out that a few German planes did have 4 blade props. I may make a follow up video about this. However the bombers so equipped didn't have central cannons, which supports my main point. The 190 V18 did, but it was a prototype and Focke Wulf gave up on it and went back to three blades and used it with their central cannon equipped fighters, I think that also supports my main point. In regards to the K-14, I dont' think it even existed.

The "109C Pictured" caption was obviously supposed to be a bit later when the 109C is pictured and I'm talking about a 109B. The editing software moved it and I didn't notice because it's white on a white background, but I'm not going to re-upload the video to fix it because my viewers are smart enough to realize that a Stuka isn't a 109, and are smart enough not to care about insignificant mistakes that have zero effect on the content being delivered.
