    Environmental control and life support system evolution analysis (1991)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: The Space Station Freedom Environmental Control and Life Support System (ECLSS) will have to accommodate the changes made to Freedom as it evolves over 30 years or more. Requirements will change as pressurized modules are added, crew numbers increase, and as the tasks to be performed change. This evolution will result in different demands on the ECLSS which will have to adapt to these changes. Technologies other than the baselined ones may be better able to perform the various ECLSS functions and technological advances will result in improved life support hardware better able to meet the new requirements.

    Environmental Control and Life Support System Evolution (1990)
    In:  CASI
    Details
    Publication Date: 2014-09-03
    Description: Viewgraphs on Environmental Control and Life Support System (ECLSS) evolution are presented. The Space Station Freedom ECLSS will have to accommodate the changes to Freedom as it evolves over the design life of 30 years or more. Requirements will change as pressurized modules are added, crew numbers increase, and as the tasks to be performed change. This evolution will result in different demands on the ECLSS and the numbers ECLSS will have to adapt. Technologies other than the baselined ones may be better able to perform the various tasks and technological advances will result in improved life support hardware having better performance, increased reliability, reduced power consumption, weight, and volume, greater autonomy, and fewer resupply requirements. A preliminary study was performed to look at alternative technologies for life support and evaluate them for their integration requirements.

    Environmental Control and Life Support System Evolution (1990)
    In:  CASI
    Details
    Publication Date: 2018-06-11
    Description: The Space Station Freedom Environmental Control and Life Support System (ECLSS) will have to accommodate the changes to Freedom as it evolves over the design life of 30 years or more. Requirements will change as pressurized modules are added, crew numbers increase, and as the tasks to be performed change. This evolution will result in different demands on the ECLSS and the ECLSS wilt have to adapt. Technologies other than the baselined ones may be better able to perform the various tasks and technological advances will result in improved life support hardware having better performance, increased reliability, reduced power consumption, weight, and volume, greater autonomy, and fewer resupply requirements. A preliminary study was performed to look at alternative technologies for life support and evaluate them for their integration requirements, focusing on the fluid line interface requirements. (A follow-on study will expand greatly on the scope of this preliminary study.) The integration requirements of the alternative technologies may be different from those of the baselined technologies. If this is the case, then by designing the initial space station to have the necessary fluid lines, etc. required by the selected alternative technologies then the task of replacing the baselined ones will be greatly simplified, thereby reducing the cost in on-orbit time as well as dollars.

    Designing for human presence in space: An introduction to environmental control and life support systems (1994)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Human exploration and utilization of space requires habitats to provide appropriate conditions for working and living. These conditions are provided by environmental control and life support systems (ECLSS) that ensure appropriate atmosphere composition, pressure, and temperature; manage and distribute water, process waste matter, provide fire detection and suppression; and other functions as necessary. The functions that are performed by ECLSS are described and basic information necessary to design an ECLSS is provided. Technical and programmatic aspects of designing and developing ECLSS for space habitats are described including descriptions of technologies, analysis methods, test requirements, program organization, documentation requirements, and the requirements imposed by medical, mission, safety, and system needs. The design and development process is described from initial trade studies through system-level analyses to support operation. ECLSS needs for future space habitats are also described. Extensive listings of references and related works provide sources for more detailed information on each aspect of ECLSS design and development.

    Environmental control and life support system evolution (1990)
    In:  Other Sources
    Details
    Publication Date: 2019-01-25
    Description: Space station growth scenarios were reviewed and environmental control and life support system (ECLSS) growth requirements and ECLSS-driven constraints derived. A broad range of advanced ECLSS technologies were evaluated for their potential of being developed for flight use. Based on these evaluations the 'hooks and scars' needed to accommodate subsystems based on the technologies were defined with particular attention to the fluid electrical interface requirements.

    ECLSS instrumentation technology development for the Space Exploration Initiative (1991)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: A study of ECLSS instrumentation technologies and an evaluation of SEI ECLSS mission requirements have identified several areas where instrumentation enhancements are required. Attention is given to the ECLSS instrument database fields including development potential, accuracy, cycle time, reliability, resolution, and selectivity. An initial list of instrumentation technologies is recommended for further development to correct each of the deficiencies identified.

    Space station ECLSS simplified integrated test (1989)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: A discussion of the Space Station Simplified Integrated Test (SIT) was conducted. The first in a series of three integrated Environmental Control and Life Support (ECLS) system tests, the primary objectives of the SIT were to verify proper operation of ECLS subsystems functioning in an integrated fashion as well as to gather preliminary performance data for the partial ECLS system used in the test. A description of the SIT configuration, a summary of events, a discussion of anomalies that occurred during the test, and detailed results and analysis from individual measurements and water and gas samples taken during the test are included. The preprototype ECLS hardware used in the test is reported providing an overall process description and theory of operation for each hardware item.

    ECLSS development for future space missions (1990)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The Environmental Control and Life Support System (ECLSS) for Space Station Freedom is presently under development. Three areas of concern for longer duration missions are recycling of mass, monitoring and controlling the ECLSS, and controlling trace contaminants and microorganisms. The goal is to 'close the loop' for water and oxygen much more than has been done on previous missions. Alternative technologies for performing each of the ECLSS functions are being developed and evaluated as part of the selection process for choosing the technologies to use on Freedom. Methods to automatically monitor and control the ECLSS are being investigated. The instrumentation needs are being determined in order to focus effort where most needed. Research is also underway to improve methods of monitoring and controlling trace contaminants and microorganisms.

    CMIF ECLS system test findings (1989)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: During 1987 three Space Station integrated Environmental Control and Life Support System (ECLSS) tests were conducted at the Marshall Space Flight Center (MSFC) Core Module Integration Facility (CMIF) as part of the MSFC ECLSS Phase II test program. The three tests ranged in duration from 50 to 150 hours and were conducted inside of the CMIF module simulator. The Phase II partial integrated system test configuration consisted of four regenerative air revitalization subsystems and one regenerative water reclamation subsystem. This paper contains a discussion of results and lessons learned from the Phase II test program. The design of the Phase II test configuration and improvements made throughout the program are detailed. Future plans for the MSFC CMIF test program are provided, including an overview of planned improvements for the Phase III program.
