Abstract
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.
Claims19
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;
- and
- a 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.

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;
- and
- a 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.

An aircraft, comprising:
- a fuselage that encloses a cabin;
- and
- a 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;
- and
- a 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.
