Hardware/Software Complex of Crew's Service of the Regeneration Life Support System Operation: Formation and Localization of Off-nominal Situations

The problems formation and localization of Off-nominal Situations (OnS) on an Hardware/Software Complex of Crew's Service of the Regeneration Life Support System Operation (HSCCSO) are considered in this paper both at functions separate system and at deviations of crew's inhabitancy controllable parameter values.

The HSCCSO is developed for the first ground long-term experiment under ‘Mars - 500’ project. The purpose of this paper is to examine HSCCSO taking into consideration the key of the future mission to Mars (extremely long duration, autonomy, complicated communication peculiarities with the ground Mission Control Center (MCC) because of signal delay, and limited stock of expendables). It is planned to simulate off-nominal and emergency situations caused by failures of on-board LSS and/or the human factor: insufficient crew efficiency, degraded professional reliability and soon.

The special attention is given problems of the OnS formation probable under operation system in the conditions of long-term autonomy manned flight, and their localization in the conditions of the restricted interference of the Land Center of control of flight or at independent decision-making by crewmembers.
