1. An aircraft propulsion system, comprising:
a turbine engine configured to exhaust gases during combustion; and
an exhaust gas condenser that extends lengthwise along a central axis, the exhaust gas condenser including:
a housing extending lengthwise between a forward end and an aft end, the housing having an interior cavity, a top side, a bottom side opposite the top side, a first lateral side, and a second lateral side opposite the first lateral side, wherein the first lateral side and the second lateral side both extend between the top side and the bottom side;
a nozzle in communication with the housing and disposed at the aft end;
an inlet air scoop attached to the second lateral side of the housing and open to ambient air;
an outlet air scoop attached to the first lateral side of the housing; and
an exhaust gas conduit bank disposed in the interior cavity of the housing, wherein the exhaust gas conduit bank includes a plurality of exhaust gas conduits and a plurality of bypass air passages, wherein the exhaust gas conduits and the bypass air passages are disposed relative to one another in an alternating configuration;
wherein the exhaust gas conduits extend axially between the forward end and the aft end, and the exhaust gas conduits are open at the forward end to receive the exhaust gases from the turbine engine and open at the nozzle; and
wherein the bypass air passages are configured to receive bypass air from the inlet air scoop and direct the bypass air between the exhaust gas conduits, laterally across the condenser to the outlet air scoop.
