Abstract

Dual-walled fluid transportation systems and related methods. The systems comprise a dual-walled fluid conduit, comprising an outer duct comprising a pair of flared end regions and a central region extending therebetween that define an outer duct internal surface surrounding an outer duct internal volume, an inner duct defining a central conduit, extending within the outer duct internal volume, and comprising a pair of flared end regions and a central region extending therebetween that define an inner duct external surface. The inner duct and outer duct define interlocking geometries and are configured to be supported with an inner duct channel completely separating the inner duct external surface from the outer duct internal surface. The methods include additively forming an outer duct wall and additively forming an inner duct wall within an outer duct internal volume of the outer duct wall with an inner duct channel extending therebetween.
