A thrust recovery valve has two flaps, with each flap controlled independently via its own rotary actuator. Embodiments of the present invention also provide a cabin pressure control system that includes one or two thrust recovery valves and the controls architecture to efficiently operate the valves. On each thrust recovery valve, only one door can be operated during flight, making less effective area change per unit time (relative to the operating both doors at the same time), allowing higher resolution of valve control. Further, the valve doors can be...
1. A thrust recovery valve comprising: a first door;a second door;a first rotary actuator controlling travel of the first door;a second rotary actuator controlling travel of the second door independent of the travel of the first door;a first crank arm fixed at a first end to a first output shaft of the first rotary actuator wherein, when the first output shaft rotates, the first crank arm swings in a rotational arc;a first link pivotally pinned at a first end to a second end of the first crank arm;a first door swing arm pivotally pinned at a first end to...
