Re: Anatomy of the Ship Iowa/Stefan Draminski

I have to disagree in part at least. As far as I know, Draminski's primary forté is 3D computer graphics, not "traditional" manual draughtmanships. And that background probably explains his emphasis on external features.

Re: Anatomy of the Ship Iowa/Stefan Draminski

Kev: Go to US Amazon for Daryl Carpenter's review and read the comments too as the latter incorporates some SN critique. I would say that criticism is quite severe. No, I don't know Draminski personally . Referring to him as Draminski is very much standard practice in Finnish as adding "Mr." (actual...

Re: Anatomy of the Ship Iowa/Stefan Draminski

Kev D, I don't know if you have read the negative comments on the Steel Navy board, but to me those comments were very legitimate. The series is called Anatomy of the Ship. Consider a book titled Anatomy of Human Body. Would you expect the book to cover e.g. heart, brain, lungs? Or would you be happ...

Re: Anatomy of the Ship Iowa/Stefan Draminski

Wasn't the newer AotS Bismarck discussed here already? I would really like to hear Draminski's own input as to how the Iowa book is such a failure. To me the very basic idea of the AotS-series is the concentrate on the innards of the ship, not on the exterior as apparently is Draminski's prime inter...

Anatomy of the Ship Iowa/Stefan Draminski

This new book received pretty bad reviews on Steelnavy board. Seems that the book is not really an "anatomy" at all, having very liite on internal details and more a colour exterior renderings book. Since apparently Draminski is a member here, I would really like to know why he has produced such a m...

Re: 3-shaft propulsion

As an alternative, perhaps a document was purchased from a private collection. Does that then obligate the purchaser to thereafter provide free copies to everyone who might want one? Bill Jurens How did the assumed private collector acquire the document? Again, as far as I know, any 3rd Reich offic...

Re: 3-shaft propulsion

Dear pasoleati, Wow ..... a great deal of fire and passion on your part. I'm just wondering why you are directing such ire toward Bill Jurens. Bill did not write the rules of the academic research game; all he has done is describe how they currently work. Without academic credentials connecting you...

Re: 3-shaft propulsion

Mr. Jurens's response flies against everything that solod historiography is. For example, the very basic foundation of the reference noting system in serious academic works is that every source must be open to checking by anyone so willing. I don't think any doctoral thesis could pass the bar if the...

Re: 3-shaft propulsion

No need to compute Bismarck hull resistance from scratch. The towing tank test results have survived. I'm not at liberty to post them, though, and I'm not entirely sure it would be productive to do so. Bill Jurens A bit strange statement for how could someone have any legal reason to prevent anyone...

Re: Battleship Bismarck: A Design and Operational History

Aa far as I know, the USN was the only one to adopt double-reduction gearing in their steam plants in large scale by WW2.

Re: Battleship Bismarck: A Design and Operational History

Folks, the Richelieu's machinery gave 155,000 shp on 4 shafts and the machinery weighed 2875 tons (=53 shp/ton). Steam conditions were 27 kg/cm2 and 350 deg C.

Re: Battleship Bismarck: A Design and Operational History

As far as I remember what Whitley says, even Scharnhorst and Gneisenau had slight differences in their machinery.

3-shaft propulsion 2

No, as I don't have the books with me now. I do recall it being mentioned at least in Whitley that German marine steam plants were relatively inefficient.

Re: Battleship Bismarck: A Design and Operational History

And despite high pressures and temperatures, German powerplants weren't particularly fuel-efficient. Question is why not.

Re: Battleship Bismarck: A Design and Operational History

Does Herr Nilsson have primary sources to support his theory? After all, to be logical, Germans should have been world leaders in large warship propulsion engineering which I doubt as e.g. Whitley's books mention plenty of inefficiencies and serious reliability issues with German powerplants.
