摘要： The present disclosure relates to a coupling (100) for a double-walled pipe having an inner wall (50) and an outer wall (60), the inner wall (50) having an inner lumen (51), and the inner wall (50) and the outer wall (60) delimiting an outer lumen (61). The coupling comprises an inner section (119) forming a passage in fluid communication with the inner lumen (51), and an outer section (117) arranged radially adjacent to the inner section (119). A material of the outer section (117) is interrupted in a radial direction multiple times in an area corresponding to a radial range between the inner wall (50) and the outer wall (60). A further exemplary coupling may have an outer section that is interrupted multiple times in the longitudinal direction.

摘要： A gas distribution system (10) for aircrafts is provided. The gas distribution system (10) comprises a corrugated hose (1) having a first connecting end (2) and a second connecting end (3), and a shroud (4) surrounding the corrugated hose (1) concentrically along a longitudinal direction (5) of the corrugated hose (1), thereby building an intermediate space (7) between the corrugated hose (1) and the shroud (4). The first connecting end (2) is configured to be connected to a gas tank (130). The second connecting end (3) is configured to be connected to a gas consumer (120). The corrugated house (1) is flexible so as to compensate for in-flight deflections of the gas distribution system (10). Also, an aircraft (100) comprising a fuselage (110), a Hydrogen consumer (120), a Hydrogen tank (130), and the gas distribution system (10) is provided. The gas distribution system (10) fluidly connects the Hydrogen tank (130) with the Hydrogen consumer (120).
