An aircraft includes a fuselage extending between a forward end and an aft end. The aircraft additionally includes a propulsor mounted to the fuselage at the aft end of the fuselage, the propulsor including an outer nacelle and the outer nacelle defining an inlet. Additionally, the aircraft includes a deployable assembly attached to at least one of the fuselage or the outer nacelle, the deployable assembly movable between a stowed position and an engaged position. The deployable assembly alters an airflow towards the propulsor or into the propulsor through the inlet defined by the outer nacelle when in the engaged position to increase an efficiency of the aft fan and/or of the aircraft.

1. An aircraft comprising: a fuselage extending between a forward end and an aft end;a propulsor mounted to the fuselage at the aft end of the fuselage, the propulsor comprising an outer nacelle, the outer nacelle defining an inlet to the propulsor; anda deployable assembly attached to at least one of the fuselage or the outer nacelle and moveable between a stowed position and an engaged position, the deployable assembly altering an airflow towards the propulsor or into the propulsor through the inlet defined by the outer nacelle when in the engaged position,wherein the engaged position is a closed position, wherein the deployable assembly blocks an airflow over the fuselage from flowing into the inlet to the propulsor defined by the outer nacelle when in the closed position, andwherein the propulsor defines an axial centerline, wherein the deployable assembly comprises a plurality of nacelle panels attached to the outer nacelle, wherein the plurality of nacelle panels translate at least partially forward of the inlet defined by the outer nacelle and rotate at least partially inward towards the axial centerline when in the closed position. 2. The aircraft of claim 1, wherein the deployable assembly comprises a plurality of blocker doors attached to the fuselage of the aircraft upstream of the propulsor, and wherein the plurality of blocker doors at least partially block an airflow over the fuselage from flowing into the inlet defined by the outer nacelle when in the closed position. 3. An aircraft comprising: a fuselage extending between a forward end and an aft end;a propulsor mounted to the fuselage at the aft end of the fuselage, the propulsor comprising an outer nacelle, the outer nacelle defining an inlet to the propulsor; and a deployable assembly attached to at least one of the fuselage or the outer nacelle and moveable between a stowed position and an engaged position, the deployable assembly altering an airflow towards the propulsor or into the propulsor through the inlet defined by the outer nacelle when in the engaged position, wherein the engaged position is a capture position, wherein the deployable assembly directs an airflow into the inlet defined by the outer nacelle when in the capture position, and wherein the propulsor defines an axial centerline, wherein the deployable assembly comprises a plurality of nacelle panels attached to the outer nacelle, wherein the plurality of nacelle panels translate at least partially forward of the inlet defined by the outer nacelle and rotate at least partially away from the axial centerline when in the capture position. 4. The aircraft of claim 1, wherein the propulsor is a fan defining an axial centerline, wherein the outer nacelle extends substantially 360° around the axial centerline. 5. The aircraft of claim 4, wherein the propulsor defines a circumferential direction, and wherein the plurality of nacelle panels are spaced along the circumferential direction. 6. The aircraft of claim 5, wherein the plurality of nacelle panels are movable generally along the axial centerline to a position at least partially forward of the inlet defined by the outer nacelle when in the engaged position, and wherein the plurality of nacelle panels are movable generally along the axial centerline to a position aft of the inlet defined by the outer nacelle when in the stowed position. 7. The aircraft of claim 5, wherein the plurality of nacelle panels each include a hinged portion at a forward end movable inward towards the axial centerline of the propulsor or outward away from the axial centerline of the propulsor. 8. The aircraft of claim 5, wherein each of the plurality of nacelle panels are movable in unison. 9. The aircraft of claim 5, wherein at least certain of the plurality of nacelle panels are movable independently of the remaining nacelle panels. 10. An aft engine for an aircraft comprising a fuselage, the aft engine defining an axial centerline and comprising: an outer nacelle extending around the axial centerline and defining an inlet; anda deployable assembly attached to the outer nacelle and movable between a stowed position and an engaged position, the deployable assembly altering an airflow towards the aft engine or into the aft engine through the inlet defined by the outer nacelle when in the engaged position,wherein the aft engine defines a circumferential direction, and wherein the deployable assembly comprises a plurality of nacelle panels spaced along the circumferential direction, andwherein the plurality of nacelle panels are movable along the axial centerline to a position at least partially forward of the inlet defined by the outer nacelle when in the engaged position, and wherein the plurality of nacelle panels are movable along the axial centerline to a position aft of the inlet defined by the outer nacelle when in the stowed position. 11. The aft engine of claim 10, wherein the plurality of nacelle panels each include a hinged portion at a forward end movable inward towards the axial centerline of the propulsor or outward away from the axial centerline of the propulsor. 12. The aft engine of claim 10, wherein the engaged position is a closed position, wherein the deployable assembly blocks an airflow into the inlet defined by the outer nacelle when in the closed position.
