Propeller

Thanx Ron, Pete and Jan,
I have looked at all the web sites and I have ordered the Eric Clutton
booklet.
I can't wait for it to arrive!
I am very interested in the mathematics that model the "ideal" shape of the
propeller. (If such exist at all...)
I wonder how deep the Eric Clutton book will go into the subject.
I suppose I could just buy one of the software packages to help with my
propeller design, but I feel like a spoilt 2 year old saying: "I wanna... I
wanna...." all the time.
I wanna understand what I'm doing and I wanna work it out myself so that I
know exactly what's going on. Maybe after I've worked out my solution, I
will buy one of the software packages to check my result.
Anyone have any ideas with regards to the nitty gritty mathematical theory
around propellers?
Regards
Andre

I would like to try my hand at making my own wooden propeller. Anyone know
of some good reference material, literature or guidelines that might help?
Questions that come to mind are, for example:
1. What wood to use and how to prepare it.
2. Design guidelines
3. Finishing
4. Balancing
5. Fitting and drilling holes for bolts.
etc.

Andre,

There is an optimum propeller for every situation, RPM, Speed, and Power ...
purpose ...

In short, a propeller is always a compromise

When you have the book start with making a prop for the wall, you will learn
a lot of how to, and what tools that is needed.

Yup!
Thanx Jan, that's a good idea...
Make one for the wall....
I don't have one for the wall yet.
I'm sure the wife will appreciate... eh eh eh! :-)
Especially since my Sonerai's wings are already standing in our dining room!

I think I have this book. If it's the one I'm thinking of, it wasn't
written for the kind of prop and horsepower I need and have.

It seemed angled toward direct drive, high speed props. The kind of
thing you'd see on direct drive Volkswagon engines.

When I tried to plot my 180 + horsepower engine at the top prop speed
of 2400 rpm, it was off the scale.

It's a screw, with an angle!

It is a straightforward design process, but with many related variables,
requiring clear-cut design criteria at the onset. The book should cover
them all.
