Hello Smilo,
Thanks! I think so too. Anyway, the way I did it this time gave a better
envelope than I was getting before.
Just for the sake of curiosity to illustrate it, hereīs a compound screenshot
of the propeller graph Table 512 and the Torque graph for the 725 Hp engine.
The difference with the other two more powerful engines is a slightly narrower
"hump", and of course that the right column goes up to 775 and 830 Hp
respectively, in the torque graph and a less pronounced "step" in the propeller
graph.
Note that the "downward hook" on the right is not of the type sometimes used
for curbing power after max. RPM. Some time ago Ivan had recommended not
using it, to allow for a more correctly defined engine power.
If I had had an extra column on the right, after the Max. Power RPM setting, I
would have liked the graph to go on horizontally, but it does that anyway, I suppose.
Eliminating the "hump" and the "step" causes abnormally low cruise powers at
correct maximum power, or conversely, abormally high maximum power at
more correct cruise powers.
So, perhaps itīs as good as it gets, as Jack Nicholson would say...
Cheers,
Aleatorylamp
