I hope we could pin this thread because finding propellor design material is quite time-consuming, and a bit difficult if you are a n00b like me.

In this thread let us link a bunch of good prop design info, so we can build our planes quicker, and more effective.

The Bootstrap Approach to Aircraft Performance
(Part One — Fixed-Pitch Propeller Airplanes)

----------------

You say your airplane's POH doesn't have some performance numbers you need? Or, because of airframe or powerplant modifications, your factory-original POH performance section is out of date? Or perhaps you need numbers for your one-of-a-kind homebuilt? Don't despair ... and don't guess! Now there's an easy way to calculate accurate light aircraft V-speeds, rates and angles of climb, thrust, drag, and much more. Aviation physicist and private pilot John T. Lowry shows you how. (This first installment deals strictly with simple fixed-pitch-prop airplanes; a follow-up article deals with constant-speed props and other complications.)

Bootstrap 1

The Bootstrap Approach to Aircraft Performance
(Part Two — Constant-Speed Propeller Airplanes)

Calculating performance numbers for an airplane equipped with a constant-speed propeller requires a different bootstrap model than was used with fixed-pitch props. In this promised follow-up to his earlier article on performance of fixed-pitch propeller aircraft, aviation physicist John T. Lowry offers a downloadable spreadsheet plus some guidance on how to use it to calculate key V-speeds and performance numbers at any given combination of loading and atmospheric conditions.

The Propeller Design Package might be useful.

Actual performance of the Spitfire's airscrew, with associated design information. Beware - small print!

Aviate
Navigate

then do anything else ending with "...ate" that's on your mind!

Got this error message when I tried to download:

Safari can’t open the page “” because it cannot redirect to locations starting with “(null):”.

Any good ideas?
