dc.description.abstractThe Environmental Control and Life Support Systems (ECLSS) ensure inhabitable interior environments for the crew members in extraterrestrial spacecrafts and future habitats. ECLSS is interconnected with other subsystems (e.g., power systems), sensors, and environmental conditions to generate breathable air, recover/reutilize wastewater and solid waste as well as regulate temperature, pressure, and humidity within the habitat. To enable the design of future resilient deep space habitats, physical aspects of ECLSS, control algorithms, and both faults and damage scenarios must be accounted for. To this end, a physics-based ECLSS model has been developed and coupled with an Interior-Environment (IE) model which is able to represent multi-zone habitat architecture. This paper will primarily focus on two ECLSS sub-systems namely the Active Thermal Control System (ATCS) and Interior Pressure Control System (IPCS). The ATCS encompassing a heat rejection loop (radiator-based) and a heat pump system based on a vapor compression cycle is designed to meet heating/cooling loads within the habitat to maintain the desired indoor temperature setpoint. The heat sink loop is not included in the conventional ECLSS model, but it has been considered as a sub-system of ECLSS due to the close interactions and possible damage scenarios that can affect the thermal management of the habitat. The IPCS controls the interior total pressure by using an air supply line connected to a storage tank and safety valves. Additionally, breathable air generator model is combined with ATCS to control air quality and concentration. The behavior of coupled ECLSS and IE model has been verified under both nominal condition and damage scenarios that result in damage propagation on the components of ATCS and IPCS. Results of various cases with different initial damaged component will be compared. The results of analyses are presented and discussed along with future development plans.
