1. A wind turbine arrangement, comprising:
a wind turbine blade;
an inflatable platform positioned in the wind turbine blade, wherein after the platform has been inflated with a gaseous fluid, the platform has a circular shape or an oval shape having an area defined by a radius of the circular shape or by major and minor radii of the oval shape, respectively, and wherein the inflated platform comprises a material that contains the gaseous fluid and is continuously distributed throughout the area; and
an inflatable outer pressure ring that surrounds the platform, wherein the outer pressure ring, when inflated with a gaseous fluid, fixes the platform in the wind turbine blade by generating a normal friction force between the platform and the wind turbine blade.
