摘要

The bulkhead (1) has a bulkhead main section (3) with a flat shape in an unloaded condition, and a frame (2), which carries the bulkhead main section and connected with a trunk, where the main section has an air-tight structure with a netlike unit (5). The netlike unit has strip units that are interlaced strips, which forms a fabric (11) in an air-tight manner. The frame is made of metallic material and/or a composite material and aluminum 7150.
