An outflow valve is provided. The outflow valve includes a frame and a first door rotatably coupled to the frame. The first door has a first side opposite a second side and a bellmouth. The bellmouth is defined by a super-ellipse, with a major axis of the super-ellipse substantially parallel to the second side and a minor axis of the super-ellipse substantially perpendicular to the second side. The outflow valve also includes a second door rotatably coupled to the frame. The first door and the second door are substantially simultaneously movable between at least a first position and a second position.

1. An outflow valve comprising: a frame;a first door rotatably coupled to the frame, the first door having a first side opposite a second side and a bellmouth, the bellmouth defined by a super-ellipse having a major axis and a minor axis, with the major axis of the super-ellipse parallel to the second side and the minor axis of the super-ellipse perpendicular to the second side, the minor axis having a first minor vertex opposite a second minor vertex, the bellmouth defined along an arc between the first minor vertex and the second minor vertex, and the bellmouth terminates at the second minor vertex; anda second door rotatably coupled to the frame,wherein the first door and the second door are simultaneously movable between at least a first position and a second position. 2. The outflow valve of claim 1, wherein the second side further comprises a profile defined between a first end and a second end of the second side. 3. The outflow valve of claim 2, wherein the profile is rounded with a continuous curvature. 4. The outflow valve of claim 1, wherein the bellmouth curves radially inward towards the first side. 5. The outflow valve of claim 1, wherein the bellmouth defines a channel that extends longitudinally from a first end of the first door to a second end of the first door. 6. The outflow valve of claim 1, wherein the second door has a third side opposite a fourth side, the third side and the fourth side interconnected via a tip section and the fourth side includes a transition such that a first end of the fourth side is offset from a second end of the fourth side. 7. The outflow valve of claim 1, wherein the first side of the first door is subject to a first source of pressure and the second side of the first door is subject to a second source of pressure, the first source of pressure different than the second source of pressure. 8. A cabin pressure control system, comprising: an actuator;an outflow valve having a frame, a first door and a second door, the first door and the second door rotatably coupled to the frame and at least one of the first door and the second door coupled to the actuator to be movable by the actuator, the first door having a first side, a second side and including a bellmouth defined by a super-ellipse having a minor axis and a major axis, the minor axis of the super-ellipse is perpendicular to the second side, the major axis of the super-ellipse is parallel to the second side, the minor axis having a first minor vertex opposite a second minor vertex, the major axis having a first major vertex and a second major vertex, the bellmouth defined along an arc that extends between the first minor vertex, the first major vertex and the second minor vertex, the bellmouth terminates at the second minor vertex, the second major vertex disposed below an exterior surface of the first side and the second side including a profile defined along a portion of the second side between a first end and a second end of the second side; anda controller in communication with the actuator that commands the actuator to move the outflow valve between at least a first position and a second position. 9. The cabin pressure control system of claim 8, wherein the bellmouth curves radially inward towards the first side. 10. The cabin pressure control system of claim 8, wherein the first door is coupled to the second door such that the actuator moves the first door and the second door simultaneously. 11. The cabin pressure control system of claim 8, wherein the first minor vertex on the minor axis of the super-ellipse is a tangency point between a surface of the super-ellipse and the second side. 12. The cabin pressure control system of claim 8, wherein the second door includes a third side and a fourth side, the third side and the fourth side interconnected via a tip section and the fourth side includes a transition such that a first end of the fourth side is offset from a second end of the fourth side. 13. The cabin pressure control system of claim 8, wherein the bellmouth defines a channel that extends longitudinally from a first end of the first door to a second end of the first door. 14. The cabin pressure control system of claim 8, wherein the outflow valve is coupled to a fuselage of an aircraft, and the second door is forward of the first door in a direction of flight of the aircraft. 15. An aircraft, comprising: a fuselage that encloses a cabin; anda cabin pressure control system coupled to the fuselage, the cabin pressure control system operable for venting a fluid from the cabin into an environment external to the aircraft, the cabin pressure control system including: an actuator;an outflow valve having a frame, a first door and a second door, the first door and the second door rotatably coupled to the frame and at least one of the first door and the second door coupled to the actuator to be movable by the actuator, the first door having a first side, a second side and including a bellmouth defined by a super-ellipse having a major axis and a minor axis, the minor axis of the super-ellipse is perpendicular to the second side and the major axis of the super-ellipse is parallel to the second side, the minor axis having a first minor vertex opposite a second minor vertex, the bellmouth defined along an arc between the first minor vertex and the second minor vertex, the bellmouth terminates at the second minor vertex, the second side including a rounded profile defined along a portion of the second side between a first end and a second end of the second side, and the second door coupled to the frame so as to be forward of the first door in a direction of flight of the aircraft; anda controller in communication with the actuator that commands the actuator to move the outflow valve between at least a first position and a second position for venting the fluid. 16. The aircraft of claim 15, wherein the first door is coupled to the second door such that the actuator moves the first door and the second door simultaneously. 17. The aircraft of claim 15, wherein the second door includes a third side and a fourth side, the third side and the fourth side interconnected via a tip section and the fourth side includes a transition such that a first end of the fourth side is offset from a second end of the fourth side. 18.
