Fluid Containers for Life Support Systems and Payloads 2003-01-2532

Two portable, collapsible water storage containers were developed to enable water logistics and storage on ISS. The first is a new version of the 44-liter Contingency Water Container (CWC) originally developed for the Shuttle Program. The new CWC uses a thicker Combitherm® film, VPCXX 140, as the bladder material. The second is a multipurpose 10-liter vessel, known as the Payload Water Reservoir (PWR), with a Teflon® bladder. Both of these collapsible vessels have Nomex® outer restraints for structural support, allowing them to withstand pressurization and resist puncture. The results of material longevity tests, the design and development of the two containers are briefly reported, and current and future water, wastewater, coolant and experiment fluid storage applications for the ISS are described.
