Definitions
- the closure element preferably projects at least partially into the core outlet opening.
- the axis of the connecting element which generally has a cylindrical shape, coincides with the axis of the core outlet opening.
- the area over which the connection to the blade is made is thus essentially the lateral surface of the connecting element. This is larger compared to the line that would be formed by a soldered seam, whereby a seal of the hollow interior of the turbine blade and the fixation can be ensured the connecting element is improved, ie a secure hold is guaranteed.
