I've find this link very informative...

The whole site has some good information.

If you like that, try out the JAVA prop program. Very neat and easy to use.

Another nice prop program (as well as an electric motor program). Look at the bottom of the page for a the prop program. What I like about this particular program is that you can fix a rpm and the look at power and torque needs as the flight speed varies.

Another bonus is that there are both Windows, Mac, and Linux versions.
Here is a link to some calculations I did for various prop parameters (pitch, diameter, # blades...) which I originally posted in the Electric forum--where the real propeller heads lurk!

That's a very useful program - in fact, in about 30 seconds I proved the point that I spent about half a week and a dyno and thrust stand test trying to convince Leonard Neumann (i.e. 4" pitch has a steeper thrust/velocity curve and a lot more static thrust than 6" pitch, when set to the level flight speed. I also discovered that my *really cheesy* prop simulation was pretty darn close and gave decent results/

Hi Brett
care to share the info about the thrust/velocity curves?
I would be interestes in seeing anything like that

Well you could check out my link.
