Eek..

Hey all..

 I have this piece of physics coursework called "research and report" in which we can choose any subject.. so being of the water world.. I have chosen to study the Type 42 Destroyer since I was told "Warships" was a bit broad and somebody else has decided to do sailing.. but... when it came to choosing what areas of physics I would study... I realised.. I don't actually know what material the hull of a Destroyer or any Royal Navy Warship is made of. I considered steel but I'm really not sure and was wondering if anyone knew for definate??

Secondly.. we have to study an area of physics we don't know much about and whilst wikipedia is amazing for most things.... does anyone know anything about hydrodynamics and would anyone be willing to explain a few areas to me? I'm finding wikipedia slightly difficult to understand.

anyone? I'm stuffed if I don't include this area of physics. :(

help. Please?

I guess this is the Physics AS coursework? Th name of the report sounds familiar. The hull might not be steel, there are some made from aluminium, caused quite a problem in the Falklands (aluminium + salt water = big fire!) but I can't remember the class, I can probably try and dig up some info. Also worth thinking about is we were told not to use Wikipedia as a trusted source as it can be edited by anyone and isn't reviewed by a expert. I still used it to help me understand stuff/find out what to research but didn't rely on it being accurate. Any particular bit of Type 42s you're interested in?

Aluminium alloys were used in the superstructure of some ships, not in the hull. Type 42s have steel superstructures and hulls.

As for the fluid dynamics, I did a course on it last year as part of my degree. It wasn't a huge amount, but seemed like it as there's only so much vector calculus I can do and still preserve the last tattered shreds of my sanity.

T42 hull is steel.  Not sure I can reveal the material properties like yield stress, but its not the highest grade.  Some more recent RN vessels use higher grade steels steels. If you can get them, there are a series of Defence Standards that would help esp DefStan 02-791.  Try www.Defstan.mod.uk, which is public access, or Dent Steels website for general steel info.

Is there a specific hydro question you have, or just a general desire to know more?

 

 

 

and thank you :) webs were gooooood :)
