Cabin pressure thrust recovery outflow valve and method that enable ram air recovery

摘要

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 (100) is mounted on the aircraft that includes a valve frame (102), a first valve door (104) and a second valve door (106). The first valve door (104) is rotated to a first predetermined open position while the second valve door (106) is in the second door closed position to thereby open first and second flow passages (402, 404) that place the aircraft cabin in fluid communication with the atmosphere. When the first valve door (104) is at a first predetermined open position, a flap (160) is rotated, relative to the first valve door to cover the second flow passage (404) and thereby inhibit flow through the second flow passage.
