Question Siemens Halske Sh.III and propeller data
Hi,

Can somebody help me with any power(torque)-rpm correlations for Siemens Halske Sh.III? Propeller diameter and pitch will be very usefull too.
I am trying to "design out" some performance data for Siemens Schuckert D.IV using Lift-vs-Drag diagram published in Technische Berichte from 1918. Such data can greatly reduce the error margin.

Another unknown variable is propeller selection - climb or speed optimized?

Regards,
Yavor

Thank you Stephen!
Unfortunately i am unable to locate Dick (or Richard) Bennett on this forum. Would you be so kind to send me a link for PM or e-mail? PM or e-mail from members list is OK.

Now i have preliminary sets of calculations for SSW D.IV performance. The real problem is within propulsion system. Calculated ceiling is 7500:7600 m with 200 hp at 1800/900 rpm sea level. Reported ceiling for SSW D.IV is above 8000 m.

Regards,
Yavor
