Amazing composite fan blade production… in high speed! 

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.....

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.

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

Not so wild ass guess: >$1,000,000 for the entire fan assembly

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

For the compressor even Aluminium works! a simple die-cast mold and one shot production

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.

Buzz Mas That's the fun part.

I needed 0.25 speed to see what was happening

Not really, its a source of pollution

Zachary Story. And now RR is trying to develop their own composite fan blades 25 years after GE did. Future is in composites.

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

@@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.
