http://www.psubs.org/design/pvho Hi Jon. Couple questions please........
#1 What is column "E" representing. "area of
nozzle cross section" @ 6 inches.
#2 Is column "D" Diameter of
nozzle ID or OD ?
I am considering a "fix" for my hull design (at a later date) and at
this point have planned on removing the main window assembly completely and
replacing the 3/8 inch thick window ring and 2 inch wide X 1 inch
thick window base ring with a 1.5 inch thick window ring and a
2.5 inch wide X 2 inch thick window base ring for the plexi disk to sit
on.
I'll get a professional FEA analysis done on the design before I "chop out"
the old one but I am trying to understand what the different values are.
I may have to replace the hatch ring assembly and two smaller window rings
too but for now am concentrating on the main window as the basis for learning
how the rules are applied.
I know this doesn't really apply to my design because I'm installing all
this stuff into the formed heads rather than a stiffened cylinder.
Thanks, Frank D.
