Simulation Model of Crew for Operation Research of Integrative Life Support Systems

2000-07-10
2000-01-2368
This paper reviews a Crew Simulation Model (CSM) for Space Vehicle Integrative Life Support System (ILSS) operation study. It is designed to simulate crew metabolic reaction mass and energy flows in accelerated time mode with each crew member specifics consideration. This CSM formally is based on human body general simulation, which includes main functional systems like: the cardiac-vascular, external respiration, thermal regulation and water/mineral balance. Work and rest time schedules are also considered as well as each crew member presence in a particular module. The CSM considers trace contaminants in metabolic products due to nutrition and environment temperature. This simulations' formal review is shown in the paper as well as formal implementation with computed experiment results. Some of the possible applications are also approached.

An Efficiency of Technologies and a Strategy for Synthesis of Integrated Life Support System Structure

2000-07-10
2000-01-2396
The research conducted at NIICHIMMASH for the past several years in the area of Integrated Life Support System (ILSS) strategy development for technology efficiency analysis and system structure synthesis is reviewed in this paper. This study proposes an generalized efficiency model for ILSS development, which includes global, thermodynamic and local quantitative and qualitative factors. The research resulted in a strategy for the synthesis of ILSS structure based on evolutionary and integral- hypothhetical approaches. This strategy allows development of new system configurations, evaluation of existing ILSS effectiveness and considers decision marker's (DM) preferences. Uncertainty in the initial information about properties of the system or technology has a big influence on DM making decisions about future system appearance. Fuzzy set theory is used to define the uncertainty in the initial information.

Development of Urine Processor Distillation Hardware for Space Stations

1995-07-01
951605
This paper describes the results of research and tests of different patterns of distillation processes for water reclamation from urine accomplished by NIICHIMMASH in cooperation with other companies. Several typical patterns of evaporation to air flow from water-retentive porous bodies, from the surface confined by capillary/porous membranes and from free liquid surface in rotary units under atmospheric and reduced pressure are analyzed. Relevant condensation processes are reviewed. Performance data for distillation unit of SS MIR system for water reclamation from urine are outlined. The paper highlights the prospects of distillation hardware development.

A Concept of Lunar Base Regenerative Water Management System Construction

1995-07-01
951603
A concept of developing a regenerative water management system (RWMS) for first lunar base missions is reviewed. The principal feature of the concept proposed is the maximum possible unification of RWMS for long-duration orbiting station and a lunar base with due regard to possible modification of the hardware for lunar gravity conditions. The paper is based on the expertise in research, development, testing and flight operation of RWMS in Russia. An upgraded RWMS of the International Space Station may be used for first lunar missions.

A Physico/Chemical System for Hygiene Waste Water Recovery

1993-07-01
932076
The paper deals with some aspects and results of research in major processes and hardware of a system for hygiene waste water recovery and its architecture concepts. A principal system schematic and its functions on Mir space station are presented. It is shown that physico-chemical means ensure cost-effective recovery with minimum energy demand and resupply which is particulary important for long-duration space missions.
