Abstract (en)
[origin: US2002015641A1] The invention relates to a honeycomb structure (1) which is arranged on a stator of a gas turbine and which is arranged opposite the moving blades of the gas turbine. The honeycomb structure (1) is composed of metal sheets (5) in such a way that webs (3) having double the sheet thickness are obtained and connections (4) of single thickness are obtained between the webs (3). The angle (alpha) between the circumferential direction (2) of the stator and the webs (3) of double thickness is 5° to 175°. This serves to avoid undesirable effects such as, for example, overheating during friction at the honeycomb structure (1) of the moving blades of the gas turbine.
