Definitions
- a sound-repellent layer which has this structure, and a large number of funnels 24 can be provided distributed over the surface, can serve as a sound absorber for a strut according to the invention.
- the present invention makes it possible to largely absorb the tonal sound outflow, in particular from low-pressure turbines.
- the sound absorber By integrating the sound absorber into existing components, no additional installation space is required, the application can be carried out almost weight-neutral and aerodynamic losses are kept to a minimum.
