12. A water recovery system for an aircraft propulsion system comprising:
a series of condensers comprising a series of passages for an exhaust gas flow, wherein each of the series of condensers comprise a top spaced radially apart from a bottom, an upper side spaced circumferentially from a lower side, a forward side, and an aft side, wherein the series of passages are defined about an engine longitudinal axis such that recovered water drains downward in a direction of gravity through the series of passages; and
an evaporator where a steam flow is generated from water separated from the exhaust gas flow for communication to a core engine.
