Lightweight structure, particularly primary aircraft structure or subassembly, as well as method for the manufacture thereof

摘要

A lightweight structure at least sectionally composed of a plurality of connected mosaic elements and/or skin mosaic elements. The lightweight structure allows an essentially load-appropriate arrangement of the mosaic elements and/or the skin mosaic elements including the optional skin. The lightweight structure requires a significantly reduced number of connecting elements, such that the assembly effort can be reduced and an additional weight reduction can be achieved. Also, two variations of a method for manufacturing a lightweight structure are provided. Large-format lightweight structures such as, for example, an aircraft fuselage cell or partial shells thereof can also be manufactured in a reliable and dimensionally accurate fashion because only mosaic elements and skin mosaic elements, with relatively small dimensions, need to be handled. Other applications of the lightweight structure include launch vehicles, rocket stages, space stations, space station modules, satellites and masts or towers of wind power plants.

1. A lightweight structure, wherein the lightweight structure is at least sectionally composed of a plurality of elements connected with each other comprising at least one of individual mosaic elements and individual skin mosaic elements, wherein the at least one of mosaic elements and skin mosaic elements each feature a base area that is bordered by a peripheral frame of the base defining closed geometric structures, which are individually joined to each other by an at least sectional connection between at least two respective adjacent sidewalls of their peripheral frames parallel to their base areas wherein the mosaic elements and the skin mosaic elements are at least sectionally connected to a skin and wherein at least one bracket is arranged between at least two adjacent mosaic elements and the skin.
