Abstract
A tank for cryogenic liquid fuel includes a tank with inner and outer shells. A support beam with its ends supported in endwalls of the outer shell extends through a central sleeve in the inner shell. Raised formations on the support beam engage the interior of the sleeve to support the inner shell within the outer shell. The sealed space formed between the shells inhibits heat conduction into cryogenic liquid fuel held in the inner shell. Pins extending transversely through the support beam prevent turning of the support beam in its endwall supports and turning of inner shell about the support beam. Getter material and radiation shielding placed about the support beam within the sleeve of the inner shell afford additional impediments to heat transfer into the inner shell.
