Background Face masks have been proven to be effective in protecting the public against
airborne transmitted diseases when fitted appropriately. However, for homemade cloth …

This paper presents a comprehensive background and historical review of propellant
management devices used throughout space flight history. The purpose of a propellant …

Abstract Creek Road Cryogenic Complex (CRCC) is the principle cryogenic fluids
technology test facility at the NASA Glenn Research Center. CRCC consists of the Small …

This paper presents fundamental performance data for three of the influential factors that are
required to design, size, and analyze screen channel liquid acquisition devices (LADs) for …

Screen channel liquid acquisition devices (LADs) are among the most promising
technologies for separating liquid and vapor phases in propellant storage tanks under …

Technologies that enable the storage and transfer of cryogenic propellants in space will be
needed for the next generation vehicles that will carry humans to Mars. One of the candidate …

To enable future in-space cryogenic fuel depots, efficient methods are required for the tank
chilldown and transfer process to minimize the amount of consumed propellant. This paper …

We derive a class of exact solutions for Stokes flow in infinite and semi‐infinite channel
geometries with permeable walls. These simple, explicit, series expressions for both …

The screen channel liquid acquisition device is vital to in-orbit management of liquid
propellant, when it is applied to large hydrogen tank, an improved design is necessary to …

In the absence of strong gravitational forces in the microgravity environment of space,
surface tension forces dominate, and special devices called liquid acquisition devices …
