Re: [ERPS] Low pressure tanks?

The top of the tank has nothing but pressurant gas in it, and can get
fairly hot during ascent.  Thin tank walls and largely-stagnant gas don't
conduct heat down to the liquid surface very well.
Also, even if the glue doesn't melt (and it may well not, some glues are 
good for 500C, and aluminum loses significant strength from about 200C) 
it might well cause problems with keeping the tank at the right pressure 
with the heating. Mixing the tank up to keep a lower temperature 
minimises that effect.
