Long-duration human space missions require intelligent regenerative life support systems that can recycle resources and automatically manage failures. This paper explores using Petri nets to model the reliability and complex interactions of such closed-loop systems. An architecture consisting of primary systems, backups, and consumable reserves is outlined. The automation system that controls everything is described. Petri nets can capture concurrency, failure modes, redundancy, and dynamic behavior. A modular modeling methodology is presented to develop hierarchical Petri net models that scale in fidelity. Elementary fragments represent failures and redundancy. Subsystem modules can be substituted for more detailed models. Analysis and simulation assess system reliability and failure response. This supports designing ultra-reliable systems to safely sustain human life in space.

Obieg wodny w obiektach kosmicznych jest kluczowy dla zapewnienia prawidłowego funkcjonowania załogi, co ma bezpośredni wpływ na powodzenie misji. Charakterystyka tego systemu zależy od rodzaju misji, czasu trwania i odległości od Ziemi. Dotychczasowe misje kosmiczne pozwoliły na wypracowanie różnych schematów rozwiązań przedstawionych w niniejszym opracowaniu. Metody udoskonalania tych rozwiązań są obecnie jednym z najważniejszych aspektów projektowania przyszłych wypraw.

The water subsystem in space objects is crucial for proper functioning of the crew, which has a direct impact on the success of the mission. The characteristics of this system depend on the type of mission, duration and distance from the Earth. The previous space missions have allowed to develop various schemes of solutions, which are presented in this study. Methods of improving these solutions are currently one of the most important aspects of designing future missions.

Armoured Fighting Vehicle (AFV) personnel are being subjected to high ambient temperatures, humidity and radiant heat loads for hours during deployments in the hot dry desert or warm humid tropical environment. The heat stress is even worst while operating the AFV in Nuclear Biological & Chemical (NBC) Protection mode. Maintaining crew 's physical and cognitive performance amidst all of the stressors of the battlefield is a huge tash. However, if the heat stress imposed by exposure to the climatic extremes of the environment can be controlled with the use of a microclimate cooling system then this allows the soldiers to remain focused on other critical tasks. Life Support System (LSS) is an integrated Microclimate and/or Individual Crew Cooling System (ICCS) integrated with NBC Protection system. The use of LSS or LSS that is complimented by Auxiliary Power Unit (APU) on modern AFVs ensures to the mounted soldiers the ability to maintain safe body temperature. This session will discuss the efficiency of LSS and LSS-APU on AFYs.
