Patent number: 11433337Abstract: This disclosure provides a two-phase separator device for separating condensate or particulate from a gas stream. In some implementations, the separator device removes water from air and may operate under micro-gravity conditions. The gas stream flows through the two-phase separator device and passes through a rotatable vane assembly along a flow path without being redirected in another flow path. Condensate or particulate in the gas stream is impacted by a plurality of vanes of the rotatable vane assembly, and the condensate is captured by features formed within the plurality of vanes. The captured condensate is accelerated radially outwardly along the each of the plurality of vanes towards a sloped inner wall, and further moved along the sloped inner wall in a direction against the flow path of the gas stream during rotation.Type: GrantFiled: August 28, 2020Date of Patent: September 6, 2022Assignee: Paragon Space Development CorporationInventors: Thomas Cognata, Brittany Lynn Zimmerman
