Forecasting Life Support Systems Functional Condition

The problem of spaceflight and manned submersibles life-support systems (LSS) guaranteeing safety and serviceability for a crew during long self-sustaining period modelling on the basis of phenomenological models is discussed in the paper. Phenomenological modelling demands the use of modern methods of the system analysis and synthesis. The analysis of traditional reliability research methods and construction of processes quality criteria has shown their insufficiency for an estimation of life-support systems.

The main goal of the paper is to illustrate a method of improving safety and effectiveness of the crew by providing greater habitability is. The developed methodological approaches to designing life support systems allow us to increase safety and comfort of the crew in extreme conditions.
