Why Don’t Jet Engines Melt?

@kktmg
that bubble demonstration is gold!

@Simple_But_Expensive
I operated gas turbine power plants for 43 years. I remember when RR announced they were manufacturing single crystal blades. Everyone at the time considered it voodoo.

@kylebailey669
This is why Materials Engineers are so underrated. As an Electrical Engineer, my hats off to you, I could never do this, absolutely insane engineering!

@CBWX
The fact that they literally grow the blade as a SINGLE crystal to prevent it from stretching is actually insanity. We tricked a rock into being one giant diamond just so we can fly.

@realSatvikAgarwal
I work at Rolls-Royce, and I have to commend you because this is such a wonderful explanation of Nickel superalloys and investment castings! I hope we make this part of our company-wide mandatory learning; it would do everyone working here a world of good. Thank you, Derek.

@AngelaPrabhu
Wow! For 40 years I’ve been wondering how single crystal blades were made. We learned about it in aircraft maintenance training but we didn’t have the fancy graphics to explain it so well then. This channel is amazing

@hollisterab
Bring back memories. I spent 10 years with GE, as a Senior Manufacturing Engineer for the F-110 and F-101 exhaust ducts, which are forward of the nozzles. Also in charge of Fan Frames for commercial and military engines, including TF-39, 80-C. Machining the HPT casing was done without coolant, using ceramic inserts, always a show, like the 4th of July, sparks galore, and .080 cut on inconel needs about 25hp to power through. I was also in charge of planning for the fan frame for the F-120, which we lost to Pratt. Back in the late 80's we were doing stuff that still today would sound pretty incredible to most people.

@gregrees9146
Most of the hot section is not just steel a lot of it is inconel which has a much higher melting temperature. Also a lot of the parts in newer engines are ceramic or ceramic coated.

They cancel you for telling the truth. Not for lying. They love the lying.

To quote the amazing Candace Owens: "Everything is fake & gay." it is the golden age of scams💯

The Fed Reserve is a Rothschild invention to destroy America. And it’s working!

@DeathByProxxy
Dude, your level of commitment, time, and detail that you put into these videos exposing the truth blows my mind! Thank you for doing what you do, brother!

@infosyphongaming4309
The thing about corporations... We work for them and make them billionaires, and they spend that money trying to find ways to eliminate us from the workforce.

@WinthropQuach
It’s almost like printing trillions of dollars and handing it to defense contractors, bankers and pharmaceutical companies might’ve hurt the working class and made the younger generation lose hope

@NelsonSenten
I was full republican. Now I’m in the middle. Some of my views have changed. How I see them attacking Candace and Tucker has made me sick. Trump hasn’t done most of what he said. No wall is built. Israel owns the White House and influencers. Israel is in everything. My views of Gaza changed after seeing that Candace interview. My 9/11 views have changed. I’m like damn dude.

What an amazing video. This should be mandatory viewing for every U S. Citizen. The sad thing, most people don't care what happens. And they won't care until it impacts their life. And then, it's too late to do anything


Ian Carroll presents a video analysis of global empire collapses through history, drawing parallels between Spain, Britain, the Soviet Union, and the current state of the United States. It argues that empires collapse from internal economic exhaustion rather than war, following a pattern of military overextension, currency debasement, debt spirals, loss of productive capacity, social decay, loss of reserve currency status, and ultimately collapse.

The United States is described as deep into this decline, with massive debt, military overstretch, currency inflation since leaving the gold standard, and social issues like rising crime and drug overdoses.

It also discusses the AI industry's current state, highlighting its rapid growth, massive investments, and the interdependent, circular financial deals among companies like Nvidia, OpenAI, and tech giants. It warns of the AI bubble's potential collapse alongside the fragile American economy, emphasizing how these dynamics fit into the broader pattern of imperial rise and fall.

Cheryl Hines x Tucker Carlson

@lloydbraun6026
She’s what a liberal was like in the 80’s. Pleasantly surprised. She’s a sweetheart.

@NicoleRoeder-h9f
You can tell by her facial expressions when she’s talking about Bobby that she really loves him! Great interview I really enjoyed it

@realderek
Great interview. My dad would have loved this. He liked Cheryl and wondered what she thought about Bobby teaming up with Trump. He died in the beginning of October or else we would have watched it together. Love you, dad.

@kathygrant8733
Wonderful interview… Cheryl just remember there are friends for a season, friends for a reason and friends for a lifetime ❤

@goddessgirl5891
Two years ago, after hearing RFKJ's News Nation town hall interview, I was absolutely blown away, and I joined his campaign as a volunteer the next day. I knew almost nothing about him, except that people said he was anti-vax. When I told my friends about joining his campaign, nearly everyone of them literally yelled at me. Not a single one of them was genuinely curious enough to ask me why I was supporting him. Not one. I'm a Republican now.

@l.w.paradis2108
I am impressed by how Cheryl Hines is still surprised at the abject rudeness she encountered. That shows a unique measure of innocence. She's just fairer than most people.

@margiewalker1808
I love Cheryl after watching this interview. She seems to be such an amazing, intelligent, strong woman. Praying for her and her family.

@knockonolan
Before Bobby ran for POTUS, Cheryl was known in Hollywood as a rare individual who had zero enemies. Everyone loved her.

@Tippycanoe-y2i
This interview with Cheryl Hines is very good. You can tell she’s thinking before she says anything and she’s very cognizant of how any words or phrase can be taken out of context. She’s the epitome of a class act. Wish there were more people in Hollywood that were as classy as her.

@michelejones4821
Cheryl seems to have a very sweet spirit, a lot of kindness toward others. She's too good for Hollywood!

@CJinSD1
They can't tolerate her presence any longer because they know that they are wrong and she's a reminder that they're lying.

@yourname1200
We all love Cheryl... thanks Tucker.

@pon1952leod
How cool is this…👍👋🇨🇦. I’m a graduate of Environmental Science in Alberta and have long admired Robert Kennedy Jrs crusade to stop corporations from poisoning us. He is a a modern day hero facing insurmountable odds but it is heartening to know that he has a kind, brave steadfast partner.❤
