- Abstract
The Mars-500 Project is to obtain the data to refine the concept of the Martian crew biomedical support and to formulate basic requirements to the concept of the mission at large including the Martian Expeditionary Complex and the Life Support Systems (LSS). Real participation of test subjects in service of the LSS in the first ground imitation of the Mars spaceflight is extremely complicated and economically unprofitable. More rational approach is application of the LSS Virtual Simulators of the separate system function incorporated in the uniform Hardware and Software Complex intended for the LSS Crew Service Operation (CSOHSC). PURPOSE of this paper is to examine the CSOHSC designed for the Mars-500 Project taking into consideration the key of the future mission to Mars (extremely long duration, autonomy, complicated communication peculiarities with the ground Mission Control Center 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 so on. APPROACH to the CSOHSC developing is based on the use of the simulation modeling for the LSS function analysis in the nominal, off-nominal and emergency conditions, the monitoring of the environmental controlled feature values and the estimation of the crew activity efficiency under the LSS off-nominal and emergency situations (ONS) and its localization. The analysis results of the LSS operating show that the CSOHSC structure should include the following interacting units: the LSS virtual simulators functions; a simulation model of the manned pressurized module (MPM) atmosphere integrating virtual simulators as a whole and providing the monitoring of controllable features of crew environment; a simulation model of the crew as an environment element defining the loadings on separate systems; a procedure for the probable ONS in operation of the LSS and TCS; a procedure for the ONS identification and representation of guidelines and rules for crew actions in case of ONS localization; a model of an estimation of the operator’s action efficiency when the ONS are localized. The CSOHSC hardware implementation is carried out for two positions, one in the MPM - the operator’s position (OP), and outside the MPM - the instructor’s position (IP). The formalized descriptions of the CSOHSC separate units and the CSOHSC program implementation executed in the LabView, v.8. 25 are considered. RESULTS of the CSOHSC software verification carried on the basis of an estimation of algorithm on discrepancy, the analysis of results of computing experiments according to balancing parities and ergonomic requirements at work of operators with front panels of the routine and subroutines of virtual simulators also as the data of the technological test are shown a reasonableness of the accepted approach for the CSOHSC design. CONCLUSIONS. 1. The basic possibility of CSOHSC designing and its application is shown when conducting a long-term ground experiment under the Mars-500 project. 2. The experimental verification of the CSOHSC carried out has shown a correctness of the accepted formalized descriptions and program implementation of the model separate components.
