Abstract: A structural element for a passenger cabin of an aircraft is built using biomimicry methods. The structural element includes a generative structure, and a functional component. The generative structure includes at least one accommodating space. The functional component is arranged within the at least one accommodating space. The generative structure includes a load topology optimized structure based on a bioinspired generative design that is configured to enable the structural integrity of the structural element while simultaneously providing integrated functionalities via the functional component. Further, an interior component for an aircraft is disclosed that includes at least one such structural element, and an aircraft including at least one structural element. For example, an aircraft galley may include a structural component that may therefore, for example, include integrated wiring, plumbing or other functionalities.

Abstract: A coupling member for coupling modules with each other. The coupling member comprises a coupling portion, which in turn has a coupling rim and at least two hook members disposed on the coupling rim. The coupling portion substantially corresponds in its outer contour to a spherical segment of a sphere with a predetermined spherical radius, wherein the coupling rim represents a circular disk of the spherical segment. In this case, an outer radius of the coupling rim is smaller than or equal to the spherical radius. The at least two hook members, in a lateral view, at least partially follow the outer contour of the spherical cap of the spherical segment. The at least two hook members are engageable with the hook members of a coupling portion of a second coupling member.

Abstract: An aircraft having a warning device for generating a whistling sound has a fuselage and a warning device. The warning device has a sound-generating element which is designed to generate a whistling sound if the aircraft is in an uncontrolled dive in the direction of the surface of the earth and there is a flow of fluid against the sound-generating element. The warning device is at least partially arranged on the fuselage of the aircraft.

Abstract: A coupling device for coupling modules with each other, comprising: a coupling surface, a primary coupling member and at least two secondary coupling members. The primary coupling member is disposed on the coupling surface. A coupling axis disposed parallel to a direction of action of earth's gravitational acceleration extends through the primary coupling member. The at least two secondary coupling members are configured to be complementary to each other and are disposed on the coupling face, and respectively have a predetermined distance from the coupling axis.

Abstract: A connection system includes a first adhesion segment, on which a first planar bonding region is formed; a second adhesion segment, on which a second planar bonding region is formed, which is shaped so as to be complementary to the first planar bonding region, and a solidifiable, liquid bonding substance. The first planar bonding region and/or the second planar bonding region are each provided with receiving openings. The receiving openings extend like capillaries through each bonding region into the interior of each adhesion segment and, in order to form an integral bond between the first adhesion segment and the second adhesion segment, are designed such that the receiving openings receive the liquid bonding substance due to capillary ascension during application of the liquid bonding substance onto each bonding region.
