ELEMENT 32.3 - INJECTING MATERIAL IN THE TRAILING EDGE
Learning objectives:
303) 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)
304) The participants can act independently in drilling injection and verification holes in the trailing edge (Ability, intermediate level)
305) The participants can act independently in injecting appropriate adhesive into the trailing edge in accordance with a work instruction (Ability, intermediate level)
The instructor shall:
Demonstrate how to:
a. determine the correct dimensions of the trailing edge bond line on a blade from a blade drawing or manufacturer work instruction
b. drill injection and verification holes along the trailing edge so that the spacing does not compromise the integrity of the trailing edge
c.
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
d. apply the knowledge gained in Lesson 21 (Painting) by applying two-factor component paint to repairs using a roller
