Continued Development and Validation of the Virtual Spacesuit Using Apollo 17 Data
(2020 International Conference on Environmental Systems, 2020-07-31)
This paper documents the continued development and further validation of a spacesuit simulation system called the Virtual Spacesuit (V-SUIT). V-SUIT is a MATLAB® application that combines models of a spacesuit pressure ...
Design for Large Isothermal Evaporator Mounted on Two-Phase Mechanically Pumped Fluid Loop
(2020 International Conference on Environmental Systems, 2020-07-31)
As the performance of mounted devices in spacecraft improves, heat density increases and accurate temperature control is required. In addition, it is necessary to control the temperature of multiple devices, and the ...
Performance of a High-power Loop Heat pipe in Variable Temperature Environments
(2020 International Conference on Environmental Systems, 2020-07-31)
This paper presents test results of an experimental study of a large-sized loop heat pipe (LHP). The main objective was to investigate the start-up and operation characteristics and the heat transfer capability in the ...
Thermal Design, Analysis, and Testing of Europa Clipper’s Radio Frequency Module
(2020 International Conference on Environmental Systems, 2020-07-31)
NASA’s Europa Clipper (EC) will conduct a series of close flybys of Jupiter’s moon Europa and investigate its ice-capped ocean. Accommodation of a solar array power architecture, a high ionizing radiation environment, and ...
Thermal design, analysis and testing of Solar Orbiter Stood-Off Radiator Assembly
(2020 International Conference on Environmental Systems, 2020-07-31)
Solar Orbiter is a solar-heliospheric ESA mission investigating how processes on the Sun drive the properties and phenomena of the heliosphere. To achieve this, Solar Orbiter will perform 22 orbits around the Sun, with ...
Chemistry of Ionic Silver and Implications for Design of Potable Water Systems
(2020 International Conference on Environmental Systems, 2020-07-31)
Ionic silver (Ag+) at approximately 400 µg/L is proposed as an ingestible biocide for potable water systems in future human spacecraft. This paper investigates the underlying chemistry of the silver ion at potable ...
Developing Metal-Organic Frameworks (MOF) to Achieve Earth-Like CO2 Levels for Advanced Space Exploration
(2020 International Conference on Environmental Systems, 2020-07-31)
"Achieving earth-like CO2 levels for space exploration requires an effective carbon removal technology that occupies minimal volume and consumes minimal energy. Metal-Organic Frameworks (MOFs) or porous coordination polymers ...
Evaluation results of aprototype vapor chamberforhigh heat flux
(2020 International Conference on Environmental Systems, 2020-07-31)
The heat generation density of spacecraft components increases with increasing the appli-cation of high-frequency devices, such as GaN amplifiers. In the amplifiers for broadcast sat-ellites, the heat flux density exceeds ...
