The answers are different, of course, but there are still some similarities. It should be another interesting thing to read about! (I didn't search but there should be some questions about this on some of the stackexchange sites) | |

| Jun 18, 2011 at 9:14 | comment | added | Georg | More interesting than number of blades I find the question why that blades cover only a small fraction of the circle they span. (At least for propellers in air). Propellers of ships or Kaplan turbine propellers cover almost the entire circle. (Independent of number of blades) | |
