GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
Explain how to position the holes so that adhesive can be injected from one side and flow across the area of debonding Explain how to inject structural adhesive into the area of debonding and how to verify that it has flowed across the de-bonded area
Explain the limitations of this method in terms of size and quality
Ask the participants relevant questions about how to drill injection and verification holes through the laminate without damaging the underlying structural parts of the blade Ask the participants relevant questions about how to inject structural adhesive into the area of debonding, and how to verify that it has flowed across the debonded area
The participants shall:
Describe in their own words and share their understanding of how to drill injection and verification holes through the laminate without damaging the underlying structural parts of the blade Describe in their own words and share their understanding of how to inject structural adhesive into the area of debonding and how to verify that it has flowed across the de-bonded area
INJECTING MATERIAL IN THE TRAILING EDGE
Learning objectives:
The participants can act independently in determining the correct dimensions of the bond line in the trailing edge from a blade drawing or blade manufacturer’s work instruction (Ability, intermediate level) The participants can act independently in drilling injection and verification holes in the trailing edge (Ability, intermediate level) The participants can act independently in injecting appropriate adhesive into the trailing edge in accordance with a work instruction (Ability, intermediate level)
Training staff shall:
Demonstrate how to determine the correct dimensions of the trailing edge bond line on a blade from a blade drawing or manufacturer work instruction Demonstrate how to drill injection and verification holes along the trailing edge so that the spacing does not compromise the integrity of the trailing edge
Demonstrate how to inject structural adhesive into the trailing edge
Facilitate practice to improve the participants’ ability to:
a. determine the correct dimensions of the bond line in the trailing edge from a blade drawing or blade manufacturer’s work instruction
b. drill injection and verification holes in the trailing edge
c. inject adhesive into the trailing edge in accordance with a work instruction
The participants shall:
