Re: Redesigning Bismarck
If you could be a bit more specific, I could try to look some numbers up. You might want to refer to the paper Strafford Morss and I wrote on the machinery plant of USS Massachusetts (BB-59) in Warship International about 15 years ago. It should be up on JSTOR. This contains a series of complete he...

Re: Redesigning Bismarck
Thank you I meant max amount of steam produced by the boilers available for propulsion and auxilliaries. I suspect its about 800 tons steam per hour for the complete powerplant at 212,000 SHP +~maybe 150 tons per hour reserve for 254,000 SHP at overload condition the article 2 only mentions the dail...

Re: Redesigning Bismarck
@ Bill Jurens
is there any information available on the max steam-heating-capacity of american battleships.
say one M type boiler can produce about 100 tons of steam at xx atm per hour?

We have the example of USS Intrepid (Essex class carrier) being able to steer with her props after a jammed rudder via a torpedo hit: http://www.researcheratlarge.com/Ships/CV11/1944MarchTorpedoDamageSteering.html Intrepid damage report: "The net result of this damage insofar as ship control w...

Re: Redesigning Bismarck
- Bismarck's propellers were of convergent design and provided only a weak turning moment. . How great is the ruddereffect from screws for a 4 screw ship. Do you have samples? At least one...would be welcome. Maintaining course without the rudder was impossible This appears wrong, Bismarck was able...

Re: Redesigning Bismarck
Regarding propulsion my personal choice would be twelve "V-Motors" 15.000 WPS each(180.000 WPS total) and four screws. the motors require about the same area but significanty less heigt compared to Bismarcks machinery spaces. But size of Bismarcks machinery probably came from a "overb...

Re: Differences between 10,5-cm (4.1") Krupp Naval guns S.K. L/40 and L/45?
1. The breechblocks of our modern cannons and quick-loading cannons. The breechblocks of our ship's guns, which have been introduced since 1880, belong to the class of horizontal wedge breechches, except for the falling breech block of the 5.2 cm 8. K. L/35. Since 1889 they have been introduced as q...

Re: Secundary guns turrets
you have to shift the lower picture by about 1-2 m. look at the transverse bulkheads.
