Hallo!
I suggest the use of javaprop to get the data
!
JavaProp
I did a little calculation with the following settings
Diameter 3,40m (correct value)
Sipnnerdiameter 0,45m (estimated)
Power 1214000W
RPM 3000
Airfoil ClarkY Re500000 for the two outer section
Airfoil ClarkY Re100000 for inner sections
Speed 60m/s
this will give you:
Durchmesser D 3,40 m
Spinner Durchm. Dsp 0,45 m
Drehzahl n 3000 1/min
Geschwindigkeit v 60,000 m/s
Blattzahl B 4
Propeller
v/(nD) 0,4 v/(ΩR) 0,127
Efficiency η 69,21 % loading medium
Thrust T 14,003,5 N Ct 0,0566
Power P 1,214,01 kW Cp 0,0327
β at 75%R 14,9° Pitch H 1,87 m
This might be not the very historical value but might be within 10% of the data from the correct modeled thing.
please find attached my java prop input file
The historical prop went from low pich 23grd to high pitch 65grd. For the analysis and modeling for the sim this can be ignored as it was designed to give the optimum thrust at given power setting.
best regard
