Abstract:
This relates to a method for manufacturing a shell-like structural component for a vehicle using additive layer manufacturing. In a step of the method, a first material is applied to a region of the shell-like structural component. In another step of the method, the region of the shell-like structural component is heated by a laser beam such that the first material is added to the shell-like structural component. The shell-like structural component comprising the first material is cooled in another step such that an internal stress is generated within the shell-like structural component resulting in a bending of the shell-like structural component. This further relates to a shell-like structural component which is manufactured by a method using additive layer manufacturing.
Abstract:
A system for installing modules on a fuselage structure has modules with holders arranged thereon for fastening on a fuselage structure, assembly stands, which can be moved on a floor level, and a flexible connecting element, extending via all the modules and coupling them together. Each assembly stand has a base for supporting the stand on the floor level and a holding device, designed to support the module. The assembly stands, the modules and the at least one connecting element are designed to form a chain of assembly stands, such that two successive groups of assembly stands enclose a pivot point at which the mutually facing modules have a larger spacing relative to one another than the modules within the respective groups. The connecting element allows the pivoting of the groups relative to one another at the pivot point through an angle of at least 90°.
Abstract:

The body is adapted to provide a controlled heat transfer from said heat generating unit to said heat sensitive supporting structure.
Abstract:
A joint device rotatably connecting a functional component to a fixing structure includes a bearing shell having a first guide body with a curved first guide face, and a second guide body with a second guide face. The bearing shell connects to either the functional component or the fixing structure. An inner body having a connection portion and a guide portion is arranged between the first and second guide faces. The connection portion connects to the other of the functional component or the fixing structure. The guide portion is movably guided on the first and second guide faces about a first rotational axis defined by the curved first guide face. The connection portion or the bearing shell connects to the fixing structure by a pin. A second rotational axis extending transversely to the first rotational axis is defined by a pin central axis and/or the first guide face curvature.
Abstract:
A rotary joint includes an outer shell segment having the outer shape of a solid of revolution, the outer shell segment having a plurality of openings arranged in the outer surface; an inner shell segment having the outer shape of the solid of revolution of the outer shell segment, the inner shell segment being aligned concentrically with the outer shell segment and spaced apart from the outer shell segment by a compensation gap; and a plurality of strut holding fixtures, the strut holding fixtures having a hollow interior and a flange portion, wherein each of the strut holding fixtures is arranged in one of the plurality of openings and the flange portion extends within the compensation gap between the inner shell segment and the outer shell segment in each case.
Abstract:
A holding device for in particular panel-shaped interior lining parts of a fuselage, has a configuration that is easy and simple to mount, each holding device includes a supporting device, which is used to anchor the holding device on a primary structure of the fuselage and comprises a joint; a connecting tube, which extends out of the supporting device and one end of which is attached to the joint; a mounting for an interior lining part, to which mounting the other, opposite end of the connecting tube to the one end is attached; and a lanyard, which is fastened to the supporting device is and the mounting and extends through the connecting tube and the length of which is greater than the length of the connecting tube.
Abstract:
An aircraft structural component comprising a panel element made of a fiber reinforced composite material and provided with an opening extending fully through the panel element. A reinforcing element made of a fiber reinforced composite material has an opening extending through the reinforcing element from a first surface to a second surface of the reinforcing element. The opening extending through the reinforcing element is aligned with the opening extending through the panel element. A bushing extends through the opening provided in the panel element and the opening provided in the reinforcing element and is adapted to receive an attachment device for attaching a load to the aircraft structural component. A connecting element connects the reinforcing element to the panel element in a region of the panel element adjacent to the opening extending through the panel element by means of a hook and loop connection.
Abstract:
A holder for connecting a module to a component of an aircraft or spacecraft includes a first holder portion having a first adhesive face and a second holder portion having a second adhesive face. The first and second holder portions are movable relative to one another in an initial state of the holder such that a portion of the component can be received between the holder portions so as to glue the holder portions to the component by means of an adhesive layer in each case. The holder has two or more guided parts which are movable relative to one another by means of mutually cooperating guide faces in the initial state of the holder. The guide faces are suitably formed for being glued together using an adhesive. The holder can be used to counter peeling stress of an adhesive connection of the holder in the region of the first and/or second adhesive face.
Abstract:
An apparatus for fastening a component to an aircraft cabin attachment structure, the attachment structure having a fastening tube with a longitudinal axis. The apparatus has an internally bored sleeve rotatably positionable on the fastening tube and an external thread. A holding body connects to the component and has two spaced-apart limbs and a bearing surface enclosed by the limbs, and on which, an internal thread configured to the sleeve external thread, is arranged. A device fixes the holding body to the threaded sleeve and the fastening tube, the external and internal threads being non-self-locking. When the holding body internal thread presses against the threaded sleeve external thread, the threaded sleeve rotates until the external and internal threads align. The fixing device connects the threaded sleeve to the holding body in a rotationally fixed manner and fixes the holding body transversely with respect to the longitudinal axis.
Abstract:
A vortex generator apparatus for an aircraft includes a surface section having a receiving recess, a vortex generator having a first edge, an opposite second edge and a vortex generator surface component extending from the first edge to the second edge, wherein the first edge is fixedly arranged in or adjacent to the receiving recess. The vortex generator surface component includes at least one electroactive polymer assembly, wherein the at least one electroactive polymer is switchable into an extended state by applying an electrical voltage and into a neutral state by removing the electrical voltage. The electroactive polymer assembly and the vortex generator surface component are configured to retract the vortex generator surface component completely into the receiving recess in the neutral state of the electroactive polymer assembly and to extend the vortex generator surface component from the receiving recess in the extended state.
