a power unit having a nozzle, the power unit configured to exhaust gas, a portion of which flows in a swirling motion, through the nozzle; and

an eductor in communication with the power unit, the eductor comprising:

a housing having an inlet, an outlet, and an inner surface that defines a flow passage, the inlet configured to surround at least a portion of the nozzle and to receive the gas, and the outlet configured to exhaust the gas;

a ring disposed in the flow passage; and

a plurality of flow straighteners extending radially inwardly from the housing inner surface into the flow passage and configured to reduce swirl motion of the gas that flows therethrough, each flow straightener including an upstream edge, a downstream edge, and a first side edge and a second side edge extending therebetween, the upstream edge angled relative to the housing inner surface, the first side edges coupled to the housing inner surface, and the second side edges each coupled to the ring.
