EP 1439121 A UPAB: 20040813 NOVELTY - The lightweight structure consists of at least one skin metal sheet (1) and stiffening elements (2), which are arranged longitudinally and/or vertically on the metal sheet and which are connected to the metal sheet using the feet (3) of the stiffening elements. The link (4) of the stiffening element consists of two legs (5,6) on the side that is turned to the metal sheet. Both legs are connected to the metal sheet using two separate joining areas (7,8). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also provided for a method for manufacturing lightweight structure components. USE - Especially for airplanes, also for liquid or gas tanks, pressure or vacuum containers, components of rockets, rocket driving mechanism, lightweight water vehicles. ADVANTAGE - Provides lightweight structure that has a differential failure behavior despite of integral design leading to reduced load tension and strain in the wing area and the immediate surrounding. Enables simple production.
