i wonder what they do with the parts that do not pass spec.. saw off most of the installation base to prevent aerospace use but leave enough to mount some on my ceiling fan..
Good point to mention, this material is not recyclable and on the other hand, the process involves kind of probability which statistically leads to a percentage of losses
Tony Liu Don't quote me on this but I think they are about $35k each. I'm a studying engineer and wanted one as a art piece but... well money, so I ended up just 3D printing one for my desk
+Timothy Nguyen The production involves a percentage of rejected products, you could have just refereed to the assembly line and asked them for a rejected piece! they would have loved to give it to you since they are not recyclable
Although carbon fiber composites are typically stronger than metallic materials, in the case of fans, the rotor blades need to be a bit thicker than their titanium counterparts as far as I am aware. The major benefit of CF is its weight, though. Lower fan weight results in higher propulsive efficieny and allows for greater fan speed (important since the drive for heigher bypass ratios to improve efficiency requires larger fans and hence the tip speed increases at the same rotational speed). Furthermore, it allows for supporting structure to be lighter (1 lbs saved on the fan allows for 5-8lbs saved in supporting structure) and secondary components such as bearings, mounts, and fan containment structures to have decreased weight as well. In terms of safety, the fan containment of CF fans is safe, as is the one of titanium (It is very unlikely that they will hit someone). As far as I am aware, CF is even a bit safer in that regard owing to the lower weight and hence lower momentum. Foreign object damage such as bird strike or icing is a different story, though. With advances in layering and trailing as well as leading edge reinforcements (NASA reports from the 70s) this problem is no longer critical.
Laminate layup is surprisingly still a manual process. Too complex for machines, yet. Note the lack of skin or hair coverings - there's detritus in your airplane's fan blades, people! Note the lack of lung protection - epoxy resins can be damaging.
@@V0YAG3R it is you that have no idea. Rolls-Royce did experiment with carbon composite fan blades in the late 60's and was one of the reasons they went bankrupt.
It seems incredible to me that a process that is so hands-on can produce such a high degree of precision.
Im A FAN of these videos.
Beautiful piece... I want one at home :')
hahahaha.
I came here by googling fan blades specifically for home decoration :)
With the low cost of just $54,300
(actual price)
for your ceiling fan? whoa.....
At TM 0:28 How did that guy survive in the Autoclave???
Saw that too. What a way to go.
Scrolling down to find this comment 😂
play thwe video 0.25 speed
the guy is not inside when they close the doors.
A work of art.
Is there titanium on the leading and trailing edges?
This was really cool to see. One note: the editing made it look like they autoclaved a guy.
excellent work
they don't show the titanium joining the carbon fiber composite....when how?
1:39 the last thing many unfortunate birds see
No thermal treatment ?

Your workers are really fast,, is it piece work
How much money does a single piece of blade cost and how many hours dose it take be made?
Not so wild ass guess: >$1,000,000 for the entire fan assembly

Can someone tell me the processes done here?
Which engine model is this?
Nice video
Amazing.
Awesome
Composites vs titanium:
Cost-wise?
Strength-wise?
Safety? (As in, which one is less likely to pierce the fan case and hit someone?)
For the compressor even Aluminium works! a simple die-cast mold and one shot production

мне нравится! годное видео
Wow!
Just a one sided layup?? or did they skip several key steps.
And it's not a metal leading edge, just paint? Seems simple

Omfg soooo much physics and math
Buzz Mas That's the fun part.
Thanks, but the rapid-fire scene cuts are more seizure-inducing than interesting. :)
I needed 0.25 speed to see what was happening
looks like cfan plant.
(per blade)
These are the types of jobs where it's critical we protect from globalization.
Not really, its a source of pollution
God bless Titanium
One day they will find out how to not make carbon fiber brittle after a few years.
Chinese Spys
this kind of work cannot be outsourced to India
this is why i only fly in planes with rolls royce engines
Zachary Story. And now RR is trying to develop their own composite fan blades 25 years after GE did. Future is in composites.

Actually RR did it in late 60's , that was the reason they went bankrupt on 1970 and were taken over the the government
