Propeller blade bend repairs

Self-explaining videos uploaded


Hello @Philip.Argyropoulos. Thank you for sharing these videos. Such repairs are not very common.
Would it be possible to describe roughly the repair procedure?


Two main methods can be used to straighten a propeller tip: 1. Heat method.
2. Mechanical method.

In the heat method, heat from a torch is applied to soften the material & prevent cracking during straighten the bent tip. The mechanical method uses a press of fork that is applied to straighten the blade tip to a more reasonable value, and then wrap heated area to control the cooling process and minimize stress. Once cooled to ambient dress area by means of sanding to remove any fork marks. After completion perform dye penetrant check for the repaired area. The decision to use heat, mechanical or both methods will depend on the propeller bent value and deformation shape.
