Low Cost Personal Life Support System

Final Frontier Design (FFD) proposes a Low Cost Personal Life Support System (PLSS) for a space suit, utilizing commercial, off-the-shelf (COTS) items wherever possible. The closed loop, Low Cost PLSS system proposed includes all the required systems for a generic EVA setup, and can be packaged effectively for outer space based applications. The use of COTS items with a minimum amount of original parts greatly reduces unit and development costs while maintaining a safe and effective means of life support. The Low Cost PLSS can be designed for “minimal use”, such that it is utilized in space and discarded on re-entry, rather than returned for maintenance and servicing, which represents a major design and operational cost barrier for current systems. The Low Cost PLSS is designed and intended to be able to be used with current space suit enclosure systems. The Low Cost PLSS is broken into three major systems as described above: the Ventilation System, the Thermal Control System, and the Electronics and Controls System. FFD has identified multiple COTS, ISO certified suppliers for most components required for the system; the components have been chosen for prior space applications or space-like environment use. The Low Cost PLSS can greatly reduce unit price for the PLSS, with parts alone costing less than $120,000, likely an order of magnitude less expensive than the current next generation PLSS system.
