FILM, FILM ARRANGEMENT HAVING A NUMBER OF AT LEAST THREE HOMOGENEOUS FILMS, RADIAL AIR BEARING, MICRO GAS TURBINE AND PRODUCTION METHOD FOR A RADIAL AIR BEARING

摘要

The invention relates to a film which is configured, as one of a number of at least three homogeneous films, to co-form a film ring arrangement, wherein the number of at least three homogeneous films can be assembled to form the film ring arrangement, and the film ring arrangement has at least one running-region circumferential section and at least one spring-region circumferential section. It is provided according to the invention that the film has a longitudinal extent L for use in the circumferential direction and a first surface section (2100) as running region, has a second surface section (2200) for forming a first spring region which adjoins the first surface section (2100) on one side in the longitudinal extent L, and has a third surface section (2300) for forming a second spring region which adjoins the first surface section (2100) on the other side in the longitudinal extent L.
