  • Patent number: 11124299
    Abstract: Transformable monuments may be positioned proximate to aircraft exit doors to utilize the doorway spaces as temporary workspaces for cabin crew or destination spaces for passengers once cruising altitude is achieved. A transformable monument includes transforming portions that extend or pivot into an aircraft cross-aisle upon actuation of an exterior latch by either hand. The transforming portions extend or pivot into horizontal surfaces for crew or passenger use while protecting the exit doors from unauthorized access by passengers inflight. Transforming portions of a single monument may extend partially or fully across the cross-aisle, or a system of two transformable monuments on either side of the exit door may collectively define the temporary space. The upper and middle sections of the monument may include additional storage or self-service compartments for providing refreshments or other amenities to passengers.

  • Patent number: 11072414
    Abstract: Aircraft and air scoop systems are provided. An aircraft includes an interior compartment, an outer skin, an air scoop, a movable element, and a passive pneumatic actuator. The interior compartment encloses a substantially constant interior air mass at a cabin pressure during flight and the outer skin at least partially defines a ventilated cavity. The air scoop is disposed on the outer skin and communicates air between the ventilated cavity and an external environment in which the aircraft is located. The movable element is movable between an open position and a closed position over the air scoop to define an air flow area through the air scoop. The passive pneumatic actuator is operatively coupled with the movable element and moves the movable element towards the closed position in response to an increasing altitude of the aircraft based on a differential pressure between the interior air mass and the external environment.
