Power craft & engines • Re: solar electric propulsion of a power kat, 6.3 m
In http://web.archive.org/web/202007100100 ... ropsim.pdf I describe my own propeller simulation program and the large propeller I designed with it, using a Clark-Y flat-bottomed foil profile. The slip is very small at the best operating point. I'll try to compare the results with your program, Heimfried.Statistics: Posted by TheoSchmidt — Sat May 14, 2022 7:27 am

[...]Another remark concerning the pitch of 117 mm of your actual screw: with btrolling motors, due to the fact that the propeller is behind the motor and is working at various speed this could not be a pitch constant propeller. So it will be a good idea to check it by your self all along […]

This is an interresting topic that I want to fully understand. So let's say that you want to achieve 6kn. at full speed with your catamaran. You are using two trolling motors that rotate the propeller shaft at around 1450 RPM at full speed. Am I correct? [...]As I understand it, the full speed RPM […]

Theo, did you design your prop yourself? You will certainly know about the free to use online tool "CAESES" basred on the work of the well known propeller experts from the Netherlands. But I had always the impression this will not be very appropriate to props for small boats, because the research is done regarding […]
