Dear Pe,
What i can offer is, since you have large variety of prop brand selection, you feed me the sectional chord lengths. For example,

APC 14 x 10 .... .... .... ...... ......
APC-W 13 x 4 ..... .... .... ...... .................................................. .............. ......
........
.......
.......



For each brand, only 1 diameter is enough, for an example APC prop, you have only 14in diameter, this data is enough because plan form design of a brand rarely differ as the diameter grow or shrink. But a different model of does i.e. APC normal and APC-W are different, then say you have APC-W 13 inch, then collect those data as well.

snip

In the above table example, the base dimension is in inch however for the rest is in meter....
Umran,
APC is a very bad reference platform, because they change the basic propeller design with evry different diameter size. In my spreadsheet I would have to use a dedicated prop constant table for APC alone! Lacking reliable reference data, it is impossible for me to produce it.
