Abstract:
A divan (10) includes a seating surface (32) and a backrest (34). In a first configuration, the backrest (34) is positioned adjacent to the seating surface (32) to support a person's back while the person is seated on the seating surface (32). In the first configuration, the seating surface (32) is disposed at a first predetermined height above a horizontal plane. In a second configuration, the backrest (34) establishes an upper bunk (94) above the seating surface. In the second configuration, the seating surface (32) establishes a lower bunk (92) beneath the upper bunk (94). In the second configuration, the seating surface (32) is disposed at a second predetermined height that is lower than the first predetermined height.
Abstract:
Trailing edge assemblies, couplers and methods for deploying a trailing edge flap of an aircraft wing are disclosed. An exemplary method disclosed herein comprises guiding an aft portion of the trailing edge flap (28) along an elongated track member (36C) as the trailing edge flap (28) moves toward the deployed position; guiding a forward portion of the trailing edge flap (28) along the elongated track member (36C) as the trailing edge flap (28) moves toward the deployed position; and accommodating transverse movement of the forward portion of the trailing edge flap (28) relative to the elongated track member (36C).
Abstract:
A ventilation louver (10) includes a first plate (52) defining a first opening (74) therein for permitting fluid flow along a first direction (128), a second plate (54) defining a vane (82) therein, the vane at least partially covering the first opening and directing the fluid flow along a second direction (130), non-parallel to the first direction, and a third plate (56) defining a louvered opening (108) therein wherein the louvered opening directs fluid flow along a third direction (138), non-parallel to both the first direction and the second direction. In a non-limiting example, the ventilation louver may be disposed in a belly fairing of an aircraft.
Abstract:
A seat (214) for an aircraft is provided that includes a seat pan (228), having a seat pan front edge and a seat pan rear edge, a backrest (218), having a backrest top edge and a backrest bottom edge, where the backrest bottom edge is articulately disposed adjacent to the seat pan rear edge, a headrest (216), having a headrest top edge and a headrest bottom edge, where the headrest bottom edge is articulately disposed adjacent to the backrest top edge, a tracking device (234) disposed beneath the seat pan and being attachable to a floor of the aircraft, the tracking device permitting the seat pan to translate in at least one of a lateral direction and a longitudinal direction, and a swivel (232) connected between the tracking device and the seat pan, permitting the seat pan to rotate with respect to the tracking device.

Abstract:
Tailplanes (24) and empennages (16) for aircraft (10) are disclosed. An exemplary tailplane (24) disclosed includes a stabilizer (30) having a fixed shape and an elevator (32) movably secured to the stabilizer (30). The elevator (32) is movable from a neutral position relative to the stabilizer (30). The stabilizer (32) and the elevator (32) define an airfoil cross-sectional shape (38) having a positive camber when the elevator (32) is in the neutral position. The positive camber of the airfoil cross-sectional shape (38) may facilitate movement of the elevator (32) during some flight conditions. Also disclosed are tailplanes (24) having camber distributions that vary along the spans of the tailplanes (24).
Abstract:
A landing gear system includes landing gear (22), an uplock (26) that is releasably engageable with the landing gear (22), an uplock hydraulic actuator (16) operably connected to the uplock (26), a landing gear hydraulic actuator (14) operatively connected to the landing gear, and a controller (C) operatively connected to the uplock hydraulic actuator (16) and the landing gear hydraulic actuator. In response to receipt of a command to deploy the landing gear, the controller (C) actuates the uplock hydraulic actuator (16) and the landing gear hydraulic actuator (14) to the UP condition and then actuates the uplock hydraulic actuator (16) and the landing gear actuator (14) to the DOWN condition. An alternative embodiment incorporates a piloted check valve (42) upstream of the landing gear hydraulic actuator. The piloted check valve (42) delays operation of the landing gear hydraulic actuator (14) until release of the landing gear (22) by the uplock (26).
Abstract:
A morphing wing for an aircraft includes a top surface, a bottom surface, a leading edge, a trailing edge, a tip, and a root. A plurality of structural ribs (76,78) is disposed between the root and tip so that they extend between the top surface and the bottom surface and intersect with a lateral axis thereof. At least one active member (88,90,92,94) connects between two adjacent structural ribs along or at a first angle to the lateral axis. The active member is actively adjustable. At least one passive member (80,82,84,86) connects between the two adjacent structural ribs along or at a second angle to the lateral axis. The passive member is passively adjustable. Adjustment of at least one active member moves the adjacent structural ribs with respect to one another, thereby morphing the wing from a first configuration to a second configuration.
Abstract:
A latch includes a first locking bolt, where a first extended position of the first locking bolt defines a first locked condition and a first retracted position defines a first unlocked condition. The latch also includes a second locking bolt, where a second extended position of the second locking bolt defines a second locked condition and a second retracted position defines a second unlocked condition. A biasing member operatively connects to the first locking bolt to bias the first locking bolt in the first extended position. A lever pivotally connects to the housing and operatively connects to the first locking bolt such that movement of the lever from a closed position to an opened position causes at least the first locking bolt to move from the first extended position to the first retracted position. A locking indicator is provided in associated with the second locking bolt.
Abstract:
An air duct includes a first chamber and a second chamber, the first chamber being defined between an air handling device and the second chamber, and the second chamber being defined between the first chamber and an environment exterior to the air duct, a plurality of first openings between the first chamber and the second chamber, a plurality of second openings between the second chamber and the environment exterior to the air duct, and a sound absorbing material defining at least a portion of an interior surface of at least one of the first chamber and the second chamber.
