hallo,
unfortunatly there are no complete testing reports on the austrian built albatross D III. at least some i am aware off .
the propellers used on DII with 185 hp was
270 dia pitch 220 blade width 215
270 225 215
270 225 230
DIII with 185 hp
265 235 185
265 235 200
265 240 200
DIII with 200 / 210 HP
280 220 200
280 225 225
280 225 235
or
268 230 210
268 230 220
270 230 220
or
275 230 200
275 230 210
275 235 215
it was mandatory that from any manufacturer from any propeller type three variations was approved
hope this datas will help KACEY in his calculations.
as i sayed before i am very cautious with all this performance datas as tey are depending on so much parameters and usually the exact circumstances are not known so comparison between planes are always difficult.
will look at the engine datas i have for more details but please be a bit patient
cheers
