The style of this video - especially the interaction between the models and the narrator, was really watchable. Well put together!

Both informative and fun. Not sure why YouTube's algorithm sent me here, but I'm looking forward to the next video Safran!

Great presentation! Shows how much of advanced technologies are needed for a single component.

I remember the days, when a lot of jet engine and rocket engine parts manufacturing processes were top secret under. Some of those key manufacturing steps are still protected as classified under Missile Technology Control Regime (MTCR) even for parts destined for the civilian aerospace industry. For this reason, I find videos like this a miracle of freedom of information.

Great video, showing also the so important grinding operation, done with Tyrolit creep feed grinding wheels :-) ! Proud to be part of this great Leap engine manufacturing process!

The component isn't a turbine blade - it's a nozzle guide vane!

Whoever you hired to direct this video deserves every penny.

I think on of the best "how it's made" videos I've ever seen!! great work

[mikeletaurus]

This was fun, and also fascinating. The intensity of the complexity and detail on which successful production depends is quite amazing.

It's interesting how "artisanal" it feels (despite the abundance of high tech tools) compared to high volume manufacturing such as car components, no wonder these engines cost so much.

French engineering is excellent! Lots of love from a German to my French brothers and Sisters this festive season <3

Great video. Whenever I'm a passenger in a plane, I think about a blade that self destructs and causes massive engine failure and explodes and we're all gonna die. Now I feel better.

[CrookedSkew]

A beautiful blend of old world and cutting edge technology working in harmony.

[lbgstzockt]

Fascinating, I never knew how much effort went into each turbine

[JudgeFredd]

More of these "making of" videos please !

Turbine Blades....one great turn...deserves another.
Beautifully produced communication.

Well done, this is the best vid of this process that I've seen to date! Full process spectrum in there, design, mold, investment cast, cmm, ndt. 👍
Give whoever made this an attaboy!

[OnerousEthic]

So cute! 0:21 Damien: “Who, me?”

1:30 The mold for casting is designed to create four parts. How cool!

Best video! hats off o the director, producer, actor

It is not a turbine blade, but a stator vane to redirect the exhaust flow into a more optimal angle to strike the next set of blades. They are whirling by at a very rapid pace. 100 to 500 times per second. Each redirect gains efficiency. All the little holes and passages allow cooling air to blast the heat away and cool the exhaust, preserving the turbine blades, while expanding even more air which is the source of thrust.
During the early '80's we had a situation and I was tasked with keeping Engine assemblies available for 2 squadrons in Bermuda. 1st, they are last in line on the supply line for aviation parts.
2 squadrons means 18 4 engined airplanes complete with propellers, gearboxes, and wonderful turbines.

3 large drums full of 1st stage stator vanes was my only hope. Empty one on a huge table, divide scrap from emergency, and that can go a couple thousand more hours. Reclaimed enough to maintain those birds for 6 months.
4 months at that effort in 130 degree hangar working 18 hrs per day 7 days per week.
You would think a nice thank you would be in order but the CNO said crossrate or get out.
