Blade Repair Standard / V5 23022026
The participants shall:
Practise the ability to safely use a small grinder and a sander to remove small areas of surface damage like pin holes, scratches, and cracks, and to create the correct surface finish for the adhesion of subsequent repair layers
ELEMENT 26.3 - REPRODUCE SURFACE PROFILE
Learning objectives:
226) The participants can perform the reproduction of the surface profile shape using filler (Skills, intermediate level)
227) The participants can act independently in applying thin layers of filler to match the surrounding profile shape of the blade (Ability, intermediate level)
228) The participants can explain the limitations of using filler in terms of short pot life and layer thickness (Knowledge, intermediate level)
The instructor shall:
Demonstrate how to apply thin layers of filler to a surface repair to match the surrounding profile shape of the blade
Facilitate practice to improve the participants´ ability to apply thin layers of filler to match the surrounding profile shape of the blade
Give constructive feedback on the participants’ ability to apply thin layers of filler to match the surrounding profile shape of the blade
Describe how pinholes and surface defects degrade the aerodynamic performance of the blade
Explain the limitations of using filler by considering the short pot life of some fillers, and how ambient temperature and humidity can affect the pot life and limitations layer thickness
The participants shall:
Practise the ability to apply thin layers of filler to match the surrounding profile shape of the blade
