The first door has a first side (50) opposite a second side (52) and a bellmouth (56). The bellmouth is defined by a super-ellipse (70), with a major axis (72) of the super-ellipse substantially parallel to the second side and a minor axis (74) of the super-ellipse substantially perpendicular to the second side (52). The outflow valve also includes a second door (32) 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.
