[PSUBS-MAILIST] Re: My "Hammerhead" 1atm sub design-

 I sat in a chair at my kitchen table and pulled out the tape
 measurer. A 3' diameter cylinder would give me enough shoulder and
 foot room. Tilting this cylinder creates a more ergonomic layout
 where the pilot can be reclined comfortably. The cylinder (without
 endcaps) is 7' long, which gives 5' of sitting room (6" more than my
 5'10" self needed when sitting straight up, so it should be good for
 much taller people- especially when reclined. The top endcap would be
 the hatch, with a stiffening ring below it with hand-holds and
 perhaps light mounts. There is a stiffening ring in the center which
 helps support the 6' long by 4' wide plexiglass window.

Check 1950s patents.  What you have sketched is the same thing
as the capsules used by the Navy to carry one man under the
Skyhook balloons.   Most of them were patented by the same
chap who did the design work on Alvin.  You may be able to
tease out of those patents some detail information that you
can use.

I'll try to look in my files.
