a question about steel battleship hull designs of the late 1800's
"Jim" wrote in message ... wrote in message ... On Jan 19, 1:11 am, Tim wrote: I've always wondered why the "modern" ironclads of the late 1800's had an odd bow design. After probably thousands of years of ship building from around the world, it seems that the bow always well overlapped the keel, that is... untill the later 1800's when the "new navy" decided that a "swept back" bow was the way to go. like for instance,the USS Main:http://www.history.navy.mil/photos/i...00/h60255a.jpg Now I know there's a lot more under the waterline than what one may realize forexample the HMS Nile. seems like the bow is almost a direct vertical, but really isn't that is unless you look below the waterline http://www.cww2.net/bbs/attachment/M...f8a67f7a4f.gif i take it the Russian Gangut is the same way: http://vmk.vif2.ru/gallery/EBR_LK_Ru.../LK_Gangut.jpg I suppose that what I'm asking is what cause the engineers to go for this design hull for about 50 years then revert back to the overlapping hull like the USS Wisconsin?http://www.usswisconsin.org/Pictures...SS%20Missouri%... Any ideas? In my very limited opinion it all has to do with avoiding the bow wave, think speed. The last pic you showed was actually pretty vertical at the water line, and there will could be a bulb or cut under the water. Look at some of the modern oil tankers and such. They have a big bulb under and forward, I have not looked at it closely but it is to disrupt the formation of a huge bow wave I would think.. I was thinking that bulb was there to house sonar. But maybe not. But then again maybe http://www.epp.goodrich.com/prodapps...nardomes.shtml |
