...blades?

 

I'd like to "spin" up a little discussion on the advantages/disadvantages of the different number of blades on a prop. Why would you choose one over the other? Is there a limit to the # of blades per unit of power output, or what's the deal?

 

I know I can google it, but I am just trying to "propel" some lively discourse and learn more in the process. No decisions to be made here, and no animals were harmed in the process blah blah...

We have just covered that very recently on this forum.

haha I guess great minds think alike...

 

seems like I'd have seen it, given i pretty much browse the forum all day at work. I'll look for the thread - do you remember what it was called or which section it was in? Thanks though Guernsey!

Click on 'What's New' (not what's new 24 hours) and track back to the title 2 Blades or 3 Blades. You will find the answers there.

If you can't find it this should help.

Thanks Alan, I found the thread, and this doc is very interesting - reading it now.

 

Not that I have any real reason to know or care, since I don't have a plane to consider it for, but it helps to keep my head in the game between lessons to read this kind stuff.
