A thrust recovery outflow valve and method for controlling the transfer of air between a cabin in an aircraft and atmosphere outside of the aircraft are provided. An outflow valve is mounted on the aircraft that includes a valve frame, a first valve door, and a second valve door. The first valve door is rotated to a first predetermined open position while the second valve door is in the second door closed position to thereby open first and second flow passages that place the aircraft cabin in fluid communication with the atmosphere. When the first valve door is at a first predetermined open position, a flap is rotated, relative to the first valve door, to at least partially cover the second flow passage and thereby at least inhibit flow through the second flow passage.

1. A thrust recovery outflow valve, comprising: a valve frame configured to be mounted on an aircraft exterior skin, the valve frame including an inner surface that defines opening through the valve frame;a first valve door rotationally mounted on the valve frame and rotatable between a first door closed position and a plurality of first door open positions;a second valve door rotationally mounted on the valve frame, the second valve door rotatable independent of the first valve door, the second valve door rotatable between a second door closed position and a plurality of second door open positions;a flap rotationally mounted on only the first valve door, the flap rotatable between a stowed position and a deployed position, the flap disposed adjacent to the first valve door when the flap is in the stowed position, the flap rotated away from the first valve door and toward the second valve door when the flap is in the deployed position, the flap moved from the stowed position to the deployed position when the first valve door is rotated to a first predetermined open position;a first actuator input structure coupled to, and extending from, the first valve door, the first actuator input structure adapted to receive a drive force and to transfer the received drive force to the first valve door;a stop pin coupled to, and extending from, the first actuator input structure, the stop pin engaged by the flap only when the flap is out of the stowed position;a flap engagement pin extending through the first actuator input structure and movable between a hold position, in which the flap engagement pin will hold the flap in the stowed position, and a release position, in which the flap engagement pin will not hold the flap in the stowed position; andan actuation pin coupled to the valve frame and configured to engage the flap engagement pin, and thereby move the flap engagement pin from the hold position to the release position, only when the first valve door is rotated to the first predetermined open position. 2. The valve of claim 1, wherein the flap is further configured to move from the deployed position to the stowed position when the first valve door is rotated to a second predetermined open position, the second predetermined open position closer to the first door closed position than is the first predetermined open position. 3. The valve of claim 1, wherein the flap engages one of the stop pin and the second valve door when the flap is in the deployed position. 4. The valve of claim 3, wherein the flap engages the second valve door when the flap is in the deployed position and the second valve door is in the second door closed position. 5. The valve of claim 1, wherein the flap engagement pin is spring-loaded toward the hold position. 6. The valve of claim 1, wherein the flap is rotationally coupled to the first actuator input structure to selectively rotate relative thereto. 7. The valve of claim 1, further comprising: a first actuator coupled to the first valve door and configured to selectively rotate the first valve door; anda second actuator coupled to the second valve door and configured to selectively and independently rotate the second valve door. 8. The valve of claim 1, wherein: the first valve door is rotatable to an angle of greater than 90-degrees with respect to the first door closed position; andthe second valve door is rotatable to an angle of greater than 90-degrees with respect to the first door closed position. 9. The valve of claim 1, wherein the first valve door and the second valve door are different sizes. 10. The valve of claim 9, wherein the first valve door is larger than the second valve door. 11. The valve of claim 1, wherein the first and second valve doors overlap when the first valve door is in the first door closed position and the second valve door is in the second valve door closed position. 12. The valve of claim 1, wherein: first and second flow passages are opened through the valve frame when the first valve door is rotated to a first door open position and the second valve door is in the second door closed position;the first flow passage is disposed between the first valve door and the valve frame;the second flow passage is disposed between the first valve door and the second valve door. 13. The valve of claim 12, wherein the flap covers at least a portion of the second flow passage when the first valve door is rotated to the first predetermined open position, to thereby at least inhibit flow through the second flow passage.
