As a kid in the 70's, a teen smoker in the early 80's and worked in and around foundries, forges, and presses, and mixed and sold casting materials and binders, I LOVED Hanging out and smoking in the "mold/pattern rooms" the carpentry was JUST AMAZING! I could lite up on hot casting parts. Basically wood machinists? got this done. As a millwright, pipefitter, electrician I built or maintained the equipment and facilities. They tell me gramps was a Seabee, Pacific.
The use of the azipod propulsion system sounds revolutionary! I wonder how much more efficient it will make marine transport in the long run compared to traditional methods.
Ballasting on a new ship is different from the ballasting on a fully loaded ship. Many ships have been lost at launching from Improper ballasting. They roll over, fill with water and sit in the mud.
@@JohnSchofield-j4iexplain why ! . When he's explaining what and why he's doing what he's doing. But it could do with a graphical explanation of what his actions are going to do and achieve, that's the only thing that's what I think is wrong or could be added as part of the dialogue.
Stainless steel props for a big cargo ship...hmmm. Never seen one . I have more than 17 years experience at sea as licensed seafarer and more than 5 years experience as ship repair engineer working in shipyard. Small props in SS, yes, they are available for other type of vessels (or fitted on outboard engines).
The stainless steel ones are made for outboard motors. We saw something Yamaha makes in the video, especially for saltwater environments. You can see by the size and the pitch they're made to move fast while minimizing cavitation. Props for container ships, etc. are made from a marine-grade brass alloy and look very different from modern props for speedboats and recreational vessels.
Thats a little propeller. The prop of a giant ship can have diameters over 15 meters. By the way are made of different brass alloys. Appart from this, good video.
About the stealth tech of a carrier… Realy? How can you not see a floating island? Who needs a radar when you can just track it 24/7 from the satelite?
I’m not exactly sure what casting of Yamaha outboard motor propellers has to do with giant ships And what does machining crankshafts have to do with giant ship propellers?
I wish people would quit using clickbait images that to the knowledgeable who already know about the material are absurd, and to those who come to gain knowledge make the actual truth seem like a let-down when it's actually quite impressive.
safety is super important or kids will have a hard time in school They will burn stuffed animals without boat safety protocol. SOme will lose their pronoun ability if the narrator isnt following safety rules,
That happens to be not quite true about it not do you need to be seen by radar admittedly the radar signature is reduced, but it’s still detectable. Typical Americans

Wow 😳 just amazing how much effort and work is put into perfection.
My dad was a pattern maker for over 40 years and made propellers up to 26 ft for multiple navys
Awesome love to watch them.

Excellent 👍👏👏
We usually use foam instead. These are usually cast once
Excellent work!
No Machining, pretty un-comprehensive presentation....

Brilliant commentary and information.
Hardly.

This is supposed to be about “Giant Ships”. Where do SS props come into that?
Impressive
good stuff 👍
Shipment is the right word for a propeller...
Why are we making outboard motor props and grinding engine crankshafts for the last 2/3rd of the video?
I don’t know what I’m talking about, but it seems like a 3D printer for sand casts wouldn’t be impossible to make
This is 2024? Surely CAD had a place here.
So good 🎉

Nerf propellers are superior
Almost nothing fits the title of the video. Click bait!
Yes it does.
This would be very hard to produce without computers and remarkable software. But it takes a human make it so.

'why would they call an aircraft carrier after a person who was known for not being able to walk and chew gum at the same time!
They've already named the Dopey Joe?
Didn’t know we had a USS joe biden?
Yea, kind of sad a crook, (Nixon), got pardoned by a crook, (Ford). As far as I’m concerned when he pardoned a crook he’s one also!!!!!!
Why name one after anyone that chewed gum?!
About the stealth tech of a carrier…
Realy? How can you not see a floating island? Who needs a radar when you can just track it 24/7 from the satelite?
Showing there is rust even in a new ship!!
how giant propellar is made for giant govt.
Nothing about the machining. Sad.
I’m not exactly sure what casting of Yamaha outboard motor propellers has to do with giant ships And what does machining crankshafts have to do with giant ship propellers?
The Gerald R Ford is undetectable to radar??

AI narration should be illegal!
It’s “ how a giant.” Or “how giant “
The casting process never progresses
FIRE THE AI
Thanks for your comment. We will try more in next videos.
how about less time for your narration. It is really offputting.
15/11 ths of a kilowatt? That's an odd way to express it.
It's more fluid than 1 & 4/11
not done with computer design.. don't believe it

nothing worse then the computer narrators , SUch a joke of ignorance
用铜合金 不是因为耐腐蚀 而是因为铸造性能略好 而且好加工 论耐腐蚀 不锈钢远好于铜合金
Of course, the material must resist corrosion, but even more important is the resistance to cavitation
