Abstract:

A bi-fold valve door and method for controlling aircraft cabin pressure are provided. The bi-fold valve door includes an aft door section and a forward door section, and only the forward door section is selectively rotated about one rotational axis to a position between a closed position and a full-open position, while the aft door section is maintained in its closed position. The forward door section is selectively rotated about the rotational axis to a full-open position to engage the aft door section, while the aft door section is maintained in its closed position. When the forward door section is in the full-open position, the aft door section and the forward door section are simultaneously rotated about another rotational axis.
