Default Looking for propeller Flange information

Is there a web site or a book on "Everything you want to know on
aircraft engine-propeller flange"?

I have done some searches on the web, but I always get to specific
propeller or engine model. They state Standard SAE #1, #2, ...
modified... Lycoming bolt pattern... Continental Bolt pattern ... which
would be equivalent to Aeronautical Standard AS127... but nothing in
general, which one to use for this or that application...

Any good reference?

SAE is selling their standard for about 50$, but I am sure I can find
the same information for much less

I have SAE AS127D --- it is a grand total of 3 pages.

The following is a summary:

SAE #1 0.375, 4.375, 5.5, 3.38, 0.624, 6, .375-24UNF-3A, 0.500, 0.500, 0.500

SAE #2 0.375, 4.750, 6.0, 3.50, 0.624, 6, .375-24UNF-3A, 0.500, 0.500, 0.500

SAE #3 0.375, 5.250, 6.5, 4.00, 0.624, 8, .375-24UNF-3A, 0.500, 0.500, 0.500

The format of the above numbers is:

Bolt Dia (in), Bolt Circle Dia (in), Flange Dia (in), Prop Thickness (in),
Drive Bush Dia (in), Number of Bolts, Bolt Thread, Drive Bush Height (in),
Bolt Minimum Thread Length (in), Max Distance of End of Bolt From Face of
Hub (in)

Generic Dimensions:

Radius on Corners of the Drive Brushes and Flange 0.03-0.06
Main Flange Centre Boss 2.248-2.250 Dia OD and 2.007-2.009 ID, 1.000" Height
above Flange
Radius between flange and Centre Boss 0.190" Max
Radius on Upper Corners of Centre Boss 0.03-0.06"

There is SAE #1 to #6 ... I have only given you the first 3 as these are the
ones that are likely to be on a light aircraft. If you want any more just
let me know.

I hope that helps. Not the same as having the standard but that should be
enough info I think.

:-))

Hi smjmitchell
Any chance of a copy of the full sizes for 1-6 please, I'm wanting to fabricate an adaptor from TCM 360 crank to Lycoming 540 prop for an engine test frame on a dyno.
Dave.
