A component alignment system for an aircraft includes a first component having a first surface including first shaped projections that repeat in at least two directions along the first surface. The component alignment system also includes a second component having a second surface including second shaped projections that repeat in at least two directions along the second surface. The first shaped projections are complementary to the second shaped projections such that the first surface is translationally and rotationally constrained relative to the second surface when the first and second shaped projections are in an interlocked position.

Particular embodiments include a mission payload mounting apparatus. The mission payload apparatus includes a pressurized door plug assembly on a side of an aircraft fuselage and a strut having a first end and a second end. The strut extends from an interior of the aircraft fuselage through the pressurized door plug assembly to an exterior of the aircraft fuselage. The first end of the strut is connected to the interior of the aircraft fuselage. One or more payloads are attached to the strut.

A reinforcing arrangement for an opening in an aircraft fuselage structure has a fuselage skin having an inner side, an outer side and a first opening with a first opening contour, and a one-piece reinforcing structure having a thickening section and at least one projecting profile. The first opening contour is surrounded on the inner side of the fuselage skin by an opening edge surface having a thickness corresponding to a thickness of the fuselage skin surrounding the opening edge surface. The thickening section has a bearing surface matched to the opening edge surface and has a receiving section facing away from the bearing surface and surrounding a second opening. The bearing surface is in surface contact with the opening edge surface, and the reinforcing structure is connected to the fuselage skin, with the result that the first opening and the second opening lie one above the other.

The present disclosure describes a bulkhead assembly for an aircraft interior comprising a pocket door mechanism (48) for supporting and guiding the movement of a pocket door; and a structural member (50) to which the pocket door mechanism is attached. The structural member is attached to a structure of the aircraft and provides support for the pocket door relative to the aircraft structure independently of any decorative member (32, 34) covering the structural member.

An assembly for arming/disarming a slide of an airplane door according to the invention comprises a system with two releasable connection mechanisms (2) linked with the door (1) and a cabin floor of the airplane, each mechanism (2) comprising a releasable connector (21b) secured to the door (1), extending at right angles to the floor on each side of a door bottom, and an anchor fitting (22b) fixed to the cabin floor. Each connector (21b) is equipped with an elastic centering element (70) and a locking/unlocking grab (25b) on the corresponding anchor fitting (22b), the connectors (21b) being linked by a girt bar (5). Each grab (25b) being rotationally mobile, one of the grabs (25b) is driven by a single command (5; 25b) which drives the other grab in rotation via the girt bar (5).

An emergency exit assembly for an aircraft, including a window frame, a window assembly having an outer surface abutting the inner surface of the window frame around its perimeter, and retaining elements spaced around the perimeter of the window assembly. The retaining elements are each connected to the window frame and bias the window assembly toward and against the inner surface of the window frame. Each retaining element has a force-release portion so that the window assembly can be disengaged from the window frame through release of the force-release portion. The force-release portion may be a frangible portion breakable upon application of the pulling force. A cable with one or more handle(s) may be connected to the retaining elements to apply the pulling force. A method of accessing an emergency exit of an aircraft is also discussed.

A cable release system configured to unlock a hold open rod mechanism or latch mechanism includes an actuator having a handle and a cable attachment. The cable release system also includes a cable connected at one end to the actuator and at another end to an unlocking mechanism associated with the hold open rod mechanism or the latch mechanism. The cable release system also includes the actuator being configured to move the cable and operate the unlocking mechanism associated with the hold open rod mechanism or the latch mechanism. The cable release system also includes the actuator and the handle being configured to be moved by personnel to move the cable and operate the unlocking mechanism associated with the hold open rod mechanism or the latch mechanism. The cable release system also includes the cable attachment including a lower slide and a release slide.

A hinge apparatus can include a frame component of an aircraft interior component, a door component coupled to an aircraft door assembly, and a linkage assembly operable to rotatably move the door component between an open configuration, a partially open configuration, and a closed configuration. The linkage assembly can include a first hinge body coupled to the door component, a second hinge body coupled to the frame component, a main link pivotably coupled to the first hinge body and having a main link surface, and a first link pivotably coupled to the second hinge body and pivotably coupled to the main link. The first link may have a first link surface that is sized and shaped to mate with the main link surface when the door component is in the partially open configuration, the mating preventing movement of the door component from the partially open configuration to the open configuration or the closed configuration. Related methods are also provided.

Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

An information projection and control system for projecting information onto a projection area provided by a vehicle door, comprising at least one control unit that generates information, for projection onto the projection area; at least one projection device that projects the generated information onto the projection area; and at least one movement sensor that detects movements in a sensing area associated with the projection area, wherein the at least one control unit is adapted to control generation of the generated information on the basis of the detected movements.
