Any reason why the foam cannot be *inside* the fuel tank?

Better: A system like one used in building isolation. It's a sandwich
system with the foam between two sheets of metal.

Problem they haven't wanted to have to address is the increase in the
weight, any changes like sandwich, increases weight. AFAIK Evne painting
the fueltank was a problem or was it just a way to save some weight?

the security problem is not the foam itself but the ice building

Because if anything came off, for any reason, it would go into the SSME?
I suspect that could spoil your whole day.

Liquid oxygen soaked into an organic material is an explosive.
So any internal insulation in the oxygen tank would have to
be non-organic.

In principle, you could immerse the LO2 tank in the LH2 tank, and insulate
the outside of the LO2 tank.

You know, that's an idea I don't think I've seen before. It's interesting
if nothing else.

Without insulation between the tanks LH2 would still boil off, oxygen
would freeze to the LH2 tank wall, and chunks of it could be shed into
the pumps. This also would be bad.

The right answers for reliability are, use a vehicle arrangement which
is not susceptible to its own detritus, and use a vehicle which is
entirely re-useable and therefore testable. For lower overall costs one
would also not use LH2.

Err, LO2 tank inside the LH2 tank, with insulation on the outside of the
LO2 tank, and on the inside of the LH2 tank.


I don't say this is a good idea.
