In Spacecraft Life Support Systems
SAE Technical Paper Series, 1998<div class="htmlview paragraph">This paper discusses the development problems of the long life hydraulic pump sets based on electrical brushless D.C. motors with hydraulic static supports. The first test results of the new brushless D.C. motors for long life hydraulic pump sets developed in NPP VNIIEM to use on the space station “Alpha” are ...

The Maintenance of a Life Support Atmosphere in Sealed Systems
American Industrial Hygiene Association Journal, 1965Abstract Two feasibility studies described here explored the conditions necessary for a life support system suitable for a manned space vehicle. White rats were placed in a closed system with a recirculating air loop. Solid potassium superoxide was used as a combination oxygen generator and carbon dioxide absorber, and potassium hydroxide was used as a

Microbiological characterization of a regenerative life support system
Advances in Space Research, 1994A Variable Pressure Plant Growth Chamber (VPGC), at the Johnson Space Center's (JSC) ground-based Regenerative Life Support Systems (RLSS) test bed, was used to produce crops of soil-grown lettuce. The crops and chamber were analyzed for microbiological diversity during lettuce growth and after harvest.

The Life Support Database System
SAE Technical Paper Series, 1991<div class="htmlview paragraph">In 1989 NASA Ames Research Center (ARC) began development of the life Support Database system. This work has progressed through initial requirements analysis, data relationships modeling, and documentation of a detailed conceptual design during the first nine months of the project, followed by a year of database ...

Whither the Life-Support System?
1980The human population of the globe has been increasing according to some superexponential law. One possible form of this relationship is: where N is the total population size, and t the time in years AD. This expression was derived by fitting a model, which assumes the rate of increase to be a weak monotonic increasing function of N, to 24 estimates of ...

Fundamentals of Life Support Systems
1996Thermodynamically speaking, man as a living creature is an open system, i.e., he exchanges matter and energy with his environment that maintains its own structure. He is living in his closed terrestrial life support system known as the “biosphere”. The biosphere is a basically closed system in terms of matter, but an open one in terms of energy.

[Habitability and life support systems].
Kosmicheskaia biologiia i aviakosmicheskaia meditsina, 1989This paper discusses various aspects of space vehicle habitability and life support systems. It describes variations in the chemical and microbial composition of an enclosed atmosphere during prolonged real and simulated flights. The paper gives a detailed description of life support systems and environmental investigations onboard the Mir station.
