Update:
I'd love to get confirmation or correction for the assumptions mentioned below.
The twin-engine model I'm testing in
Phoenix has a 50-inch wingspan and weight of 60 ounces. Two 64mm EDFs of the type I'm considering have a combined published thrust of 2.8 kg, or 99 ounces.
For my testing of a turbine version of the
Phoenix model, I used the following turbine specs:
Max RPM: 50,000 (based on published figures for the EDF)
Max. Thrust: 10. I'm assuming "N" in the
Builder list means "newtons." If not, please let me know. The published thrust of the EDFs I'm thinking of using is 13.7 newtons. To be conservative, I'm using 70 percent of the published thrust.
Engine: Medium electric. Is my assumption correct that this value is mainly for the sound rather than performance? If so, it seems appropriate because it gives a hum but not the roar of the turbine options.
One question: The depiction of the turbine in
Builder is large, as seen in the image below. Does it matter? When I use
Edit to look at published turbine models, the turbines look much smaller. I tried changing the
Scale values to make the image smaller, but nothing changed. Is the size of the image relevant to the performance of the model in
Phoenix?
Thanks,
Bill
