Let's say you've stripped out the seats, galley, and overhead bins, etc.
of a jet and then re-engined. What about the new operating ceiling? Is
it strictly a Thust/Weight/Alt envelope of are there structural issues?
-Gregory
Optional Info.. additional read
With GTW of 118,000 lbs (definitely on the light side) was able
to climb direct to FL410, ~1500 fpm near the top with the latest
conversion. Cruise at M.84 reading EPR 1.88 and N1 ~86%.
Ok to go higher? or are there structural/pressurization limits? If one
takes an old sled with three JT8D-7's then strips out the interior and
adds JT8D-200 powerplants (typical MD-80?) what happens to the
Max Ceiling then? |

Who cares if you can't get a good sandwich and coffee after you threw
away the galley??? Could be a real bummer!

You can get a good sandwich and coffee on a plane?

Sure.. make the sandwiches at home, bag em' and put in cooler. Put
coffee in thermos.

Yes, and yes, although you may need to start wearing oxygen. The only
real limitation is the ability of the fuselage seals and bleed air
systems to keep the cabin pressurized; much above that and you'll start
to blow seals and lose pressure (the structure will be just fine, but
the cabin may rapidly decompress, reacquainting you with just how cold
and airless 41,000 feet can be). 
I wouldn't suggest doing something like this in reality, though, unless
you were being paid scads of money (and a pressure suit).

I would think that there might be issues on the fuselage structure as the
higher you go the greater the relative pressure on the fuselage. One reason
for a pressurised aircraft's life being limited by the number of t/offs &
landings is the frequency of the pressurise/de-pressurise cycle (I think
<g>) :-0))

Thanks.. would you like a custom, modular and removable coffee mess
installed too? what.. a DoD type? that will be 10x the cost! :<]

Crash
I have the answer. Go on a pre-flight diet, a starvation diet, then
any picnic will weigh less than the sandwiches.
Feed me! Feed me NOW!
