Liquid transfer demonstration on board Apollo 14 during transearth coast
Author(s): Abdalla, K. L.; Otto, E. W.; Symons, E. P.; Petrash, D. A.
Abstract: The transfer of liquid from one container to another in a weightless environment was demonstrated by the crew of Apollo 14. A scale-model liquid-transfer system was used on board the spacecraft during the transearth coast ...
NASA Center: Glenn Research Center Publication Year: 1971
Added to NTRS: 2005-10-13
Accession Number: 72N11285; Document ID: 19720003636; Report Number: E-6481, NASA-TM-X-2410
Contoured tank outlets for draining of cylindrical tanks in low-gravity environment
Author(s): Symons, E. P.
Abstract: An analysis is presented for defining the outlet contour of a hemispherical-bottomed cylindrical tank that will prevent vapor ingestion when the tank is drained. The analysis was used to design two small-scale tanks that ...
NASA Center: Glenn Research Center Publication Year: 1979
Added to NTRS: 2005-10-13
Accession Number: 79N29467; Document ID: 19790021296; Report Number: E-9969, NASA-TP-1492
Vapor ingestion in Centaur liquid-hydrogen tank
Author(s): Symons, E. P.
Abstract: Vapor ingestion phenomena were investigated using scale models of the Centaur liquid hydrogen tank to determine the height of the free surface of the liquid when vapor is intially ingested into the tank outlet. Data are ...
