Technical training
Blade Repair Standard / V5 23022026
The participants shall:
Practise the ability to repair cracks running parallel to the trailing edge by using a temporary hardback repair to support the laminate repair on one side of the trailing edge and then removing the temporary hardback and completing the repair by laminating the remaining side of the trailing edge
Practise measuring the hardness using a Barcol and/or a shore D hardness tester
ELEMENT 29.4 - RECREATING BLADE PROFILE
Learning objectives:
277) The participants can perform the recreation of the trailing edge profile using filler (Skills, intermediate level)
278) The participants can act independently in recreating the trailing edge profile using filler (Ability, intermediate level)
The instructor shall:
Explain the importance of recreating the aerodynamic profile of the blade
Demonstrate how to:
a. apply filler to the repair to cover the repair and to approximately match the surrounding aerodynamic profile of the trailing edge
b. use a sander to shape the filler to match the surrounding aerodynamic profile and create the correct surface finish for the adhesion of the paint layer
Facilitate practice to improve participants’ abilities to:
a. use filler to cover the repair and to match the surrounding aerodynamic profile of the blade
b. use a sander to shape the filler to match the surrounding aerodynamic profile, and create the correct surface finish for the adhesion of the paint layer
c. apply the knowledge gained in Lesson 21 (Painting) by applying two-factor component paint to repairs using a roller
Give constructive feedback on the participants’ above practice
