Incredible😍 Can you share some details about how to get into this work. I am already working in composites industry in automotive sector but i want to move into wind turbine area. Please let me know.

Hello, nice video! Can i ask what type of tape is used to fix the plastic bad used in the vacuuming?
@kymchapman1110 Жыл бұрын
This is sealant tape/ tacky tape.

@0:26 seems like you overlapped the last BX over the paint. Why is that?
@kymchapman1110 Жыл бұрын
This was the direction given by the engineers who created the repair procedure. This was an additional cover ply, which was later sanded down, exposing the original coating prior to applying fillers/coatings.

What were the repair materials used? Fiber glass type? Resin type? Would appreciate if you can mention the materials used in the repair process

I saw the bubbles coming through on the vacuum pipe, was it not full of porosity? Do you not clamp the resin intake off after infusion is complete?
@andrewlaing9801 2 жыл бұрын
Vacuum pipe will go to a catch pot. So the pump will be protected from the resin.
@BobMarley-yq3wi 2 жыл бұрын
@@andrewlaing9801 that’s not what I mean. I’m talking about the component not the pump. Porosity is caused by an air leak on the intake or resin that was not gassed off after mixing. Clamping the intake after infusion not only stops further porosity, it helps locks the resin and gives a more consistent matrix.

I would be interested to see the resin intake setup. Can you describe what you did there?

Hi Frank, this is a pretty typical Resin Infusion Lamination. Easy Composites have some excellent tutorials with great explanations. I've linked one of their videos below. kzfaq.info/get/bejne/p7OAhqx8y9HIpIU.html

What i dont understand is why u did round corners on the first 2 or 3 layers and the other layers not?... Usually u make none or when need to make it, you make in all layers, not only the first 2 or 3 layers...

So it was hard to assess from the video how long did it take.. So how many days or hours did it take to do this three bearing replacement?
@kymchapman1110 3 жыл бұрын
About 2 days for the work captured in this video, but there's about 4 days work from shut-down to restart of the turbine.

This is totally different from how we lay up glass on the blade. This looks so much better then how we do here at GE. Im amazed cause i was wondering why he was putting the glass down dry and then all of the sudden saw the resin coming in to the repair……MY MIND IS BLOWN

In the factory, it is normally by infusion method. In the field, depending on the size of the defect and the number of fibers affected, the manufacturer may or may not require infusion rather than manual lamination, to ensure quality of the repair. But for most repairs, it's no infusion required.

Hey mate thanks for the video! What was the cause of the damage ?
@JoaquimdeOliveira 2 жыл бұрын
Manufacturing defect. These type of repairs of this dimension are manufacturing defects. or design defect (in new blade models sometimes it happens)

Hi Kaneda, this particular blade was damaged during transportation. The Trailing Edge of the blade struck an object causing the bond line adhesive to crack and delimitate the surrounding fibreglass.

Why resin?. Use film adhesive and a controlled Heater mat. Resin to heavy, less tensile strength , and will mess up final balance moments. I did the Engineering side helicopter blade repair for 35 years.

Great video! I love how your videos show the realities of wind turbine maintenance 😀 It would be cool to see footage of the technicians climbing as well. Until I climbed myself I could never believe how much effort it is to get up there, even for a five minute job. Once I did that a few times I really understood that reliability is so much more critical for wind turbines than most other engineering applications.

This is great footage, I would love to use it in one of my upcoming videos on the concept of design lifetime, to illustrate why pitch bearings are designed to last the full turbine lifetime without being replaced. Could you let me know if you would give permission for me to use the video?

How often does typical commercial blade bearings needs to be replaced or repaired?
@kymchapman1110 4 жыл бұрын
This is a difficult question to answer, and one that I'm probably not entirely qualified to answer. However, I do know that they aren't typically a component that is replaced, they're usually expected to last the life of the turbine.
