1. An electric propulsor, comprising:
a core cowl;
an outer cowl, a first air flowpath being defined outward of the outer cowl and a second air flowpath being defined between the core cowl and the outer cowl;
one or more electric machines disposed in the core cowl;
a fan having a plurality of fan blades, the fan being rotatably drivable by at least one of the one or more electric machines in the core cowl;
a booster having a row of plurality of airfoils disposed at least in part in the second air flowpath between the core cowl and the outer cowl, the row of plurality of airfoils being rotatably drivable by at least one of the one or more electric machines in the core cowl for compressing air flowing along the second air flowpath; and
a heat exchanger disposed within the second air flowpath immediately downstream of the row of plurality of airfoils of the booster between the core cowl and the outer cowl, the heat exchanger being in thermal communication with at least one of the one or more electric machines.
