Method for increasing the service life of rotor blade locking means |
| 摘要 |
The rotor comprises a rim (10) on the periphery (12) of which several removable blades are fastened. The blade fasteners comprise a dovetailed groove (14) and a foot fitted in the groove. The groove is shot blasted by projecting balls (1) in order to create a pre-stressed compression in its surface. The shot blasting is carried out by ultrasonics, the balls being projected by the percussion of a vibrating sonotrode (30). The balls are contained in an enclosure (40) in which they form a mist. |
