Re: [PSUBS-MAILIST] concept sketch

["Sean T. Stevenson" <cast55@telus.net>]

Actually, I was working on a single hull design, fitting everything in, 
and thinking that it was getting way too long to be reasonable.  I was 
working out how much larger a diameter of the pressure hull I would need 
to shorten it to something reasonable, when I noticed The Hunt for Red 
October on my bookshelf.  So the short answer is yes.

As far as building it, I don't think so.  I'm not in the business, and 
certainly am not able to capitalize such a project.  It is a useful 
design exercise, though.  I have already learned a few things in the 
process.  I took all of the hull strength calculation formulae in the 
ABS guidelines and wrote them into a MATLAB program which attempts to 
optimize the hull design.  The program isn't done yet, but when it is it 
should save lots of time.  Using a provided minimum internal diameter 
and working depth, the program uses a lookup table of structural 
sections with their properties, and iterates through hull designs using 
every possible combination of stiffener section, number of heavy 
stiffeners, number of non-heavy stiffeners, internal versus external 
stiffening, and incremental plate thicknesses starting with the provided 
minimum diameter, to converge on a solution which results in the lowest 
overall volume of steel necessary for fabrication.
