Cryogenic Composite Tanks and Lines
During FESTIP 1 and 2, a feasibility study was carried out to assess the possibility of replacing all-metal cryogenic fluid
transfer lines for launchers, with composite lines with low mass and good thermal insulation properties. This feasibility study
took as reference the Ariane 5 feed line dimension: inside diameter of 185mm, with the length limited to 1m. Different
techniques to design and manufacture such items using composite materials concluded that there are two different ways, both
using filament winding technique for composite components: Single wall piping -composite piping with a metallic barrier/liner to
reduce the gas diffusion at cryogenic temperature; Double walled, vacuum insulated cryogenic composite line, which further
reduces the heat leaks through the system. The goal of this activity is to further develop the technology for designing and
manufacturing light-weight cryogenic tanks and lines based on composite technology. Substantial mass reduction for
cryo-tanks and lines is expected while at the same time the parasitic heat leaks will be reduced thereby increasing the lifetime
of cryogenic storage (stand-time).The following tasks are envisaged:- adapt/develop processes, procedures (e.g. machining
steps, welding) to produce small diameter lines including fittings and connections as well as cryo-tanks- design and
manufacture a cryo-tank with some appropriate cryo-lines- perform a complete thermal and mechanical test programme with
the built H/W to derive e.g. stand-time, parasitic heat leak, leakage.
Deliverables:
Processes and procedures to produce light-weight cryo-tanks, lines and systems based on composite technology. H/W: fully
tested (thermal and mechanical) cryo-tank and lines.
