Theoretical Analysis of Stability for Hybrid Life Support Systems with Catalytic Incineration of Deadlock Products (Experiences with Russian BIOS-3 Project) 2009-01-2579

This work represents an extended analysis of the mathematical model which was originally developed in an attempt to analyze the process of plant biomass incineration as a source of carbon dioxide for plant photosynthesis and growth and its effects on closed ecological system stability, Mathematical modeling has demonstrated that when the limit value of intensity of production processes and matter turnover specific for every closed ecosystem is exceeded, the gaseous toxic agents destroy the system. In order to illustrate further the performance and application of the proposed model, the hypothetical optimized ecological life support system was investigated, The preliminary results suggest appropriate system parameters for further engineering implementation. The results of the theoretical analysis are verified and supported by quantitative estimates from the Russian Closed Ecosystem (CES) BIOS-3 which was tested for extended life support between 1970 and 1990.
