Stuart Slade has a few excellent hydro-articles at warships1.com. In on article he comments that Hipper’s ship without the center shaft only gains 1 knot. Slade concludes the center shaft is not very efficient. Although I really like his articles, this conclusion I strongly do not agree with. This is another discussion, but I think center shafts are good, efficiency wise.
Who could say ‘no’ to such bait!
Beeing aware of Stuart Slades fine articles on warships1 and being aware that the two shaft SMS Prinzregent Luitpold (missing the centre shaft end engine) could easily run in company with her three shafted sisters – a three shaft arrangement looks fairly inefficient to me.
And that is without Stuart’s criticism regarding vibrations in ships with an odd number of screws evens mentioned.
Foeth, would you enlight me on the issue why in your view a three-shaft arrangement might be a fine solution after all? If it is understandable to a simple Physicist, I would be delighted to here you on this topic!
So many Thanks!
Oh - and the rest of us - any other ideas on that old issue out there guys?
