Abstract: A composite sandwich panel comprises a top layer, a bottom layer, and a honeycomb core layer sandwiched between the top layer and the bottom layer. The honeycomb core layer includes an array of hollow cells formed between vertical walls. This array of hollow cells is recessed in the form of a channel network running from a first side face of the sandwich panel through the honeycomb core layer to a second side face, opposite to the first side face of the sandwich panel.

Abstract: A tie rod includes an elongate tie rod body of substantially uniform cross-section, the tie rod body comprising at least eight columns that run parallel to each other and are placed in a circumferential formation around a central axis of the tie rod.

Abstract: A passenger seat arrangement for a transport vehicle has at least one first passenger seat or row of seats having a first backrest, at least one second passenger seat having a second backrest which, by its rear side, faces the rear side of the first backrest, and a seat supporting frame. The seat supporting frame comprises a first backrest reinforcing strut which is arranged along the first backrest at a first inclination angle with respect to the horizontal, and a second backrest reinforcing strut which is arranged along the second backrest at a second inclination angle, supplementary to the first inclination angle, with respect to the horizontal.

Abstract: A rod connection system includes a first structural member having an angled pin connector integrally formed at an end portion of the first structural member with angled pins being spaced apart from and protruding parallel to an end face of the first structural member. The rod connection system further includes a second structural member having an angled socket connector integrally formed at an end portion of the second structural member with angled tubes as sockets for the angled pins of the first structural member. The angled tubes are spaced apart from and protruding parallel to an end face of the second structural member.

Abstract: A cover panel for a core panel of a structural aircraft component includes a protection cover having an outer shape corresponding to the outer shape of the core panel and including at least one cutout aperture, and at least one fabric panel mounted to the protection cover and covering the at least one cutout aperture.

Abstract: A computer-implemented method for space frame design involves constructing a load stress map in a geometrical boundary representation of a design space, defining attachment points and load application points in the design space, creating a starting network of interconnecting lines between each two of the attachment points and load application points in the design space, assigning load application factors to each line of the starting network of interconnecting lines based on values of the load stress map, generating potential space frame designs by culling different subsets of lines of the starting network of interconnecting lines for each potential space frame design according to variable culling parameters, evaluating the potential space frame designs with respect to optimization parameters, combining the culling parameters for the potential space frame designs the performance score of which is above a predefined performance threshold, and iterating the steps of generating potential space frame designs and e
