Abstract
A thrust recovery outflow valve includes a valve frame for mounting on an aircraft exterior skin and a bi-fold valve door that is mounted within the valve frame. The bi-fold valve door includes an aft door section, a forward door section, and a ram air flap. The aft door section is rotatable between an aft door closed position and an aft door full-open position and has a ram air opening formed therein. The forward door section is rotatable between a forward door closed position and a forward door full-open position. The ram air flap is rotationally mounted on the aft door section and is rotatable between a flap closed position, which prevents air flow through the ram air opening, and a flap open position, which allows air flow through the ram air opening.
