Abstract:
In combination with a structure having an outer shell enclosing a tubular chamber in protective relation to an external environment; means for storing fluid within said chamber during travel of the structure through said external environment, comprising: inner support means peripherally positioned within the tubular chamber in spaced relation to the outer shell for establishing a peripheral storage space; flexible means peripherally sandwiched in helical wound condition within said storage space between the inner support means and the outer shell for retention of the fluid therein; including: radially inner and outer hoses in contact with the inner support means and the outer shell at spaced contact points; insulation means filling all interstices about and between the hoses within the peripheral storage space for thermal protection of the fluid therein; and access means connected to the structure for injection of the fluid into the hoses to be stored therein within the peripheral storage space.
