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.
@@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.
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.
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.
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.
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?
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.
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

Awesome love to watch them.
Excellent 👍👏👏
Brilliant commentary and information.
Hardly.

My dad was a pattern maker for over 40 years and made propellers up to 26 ft for multiple navys
Impressive
good stuff 👍
Excellent work!
No Machining, pretty un-comprehensive presentation....

Shipment is the right word for a propeller...

This is supposed to be about “Giant Ships”. Where do SS props come into that?

Nerf propellers are superior
how giant propellar is made for giant govt.
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.
We usually use foam instead. These are usually cast once
Why are we making outboard motor props and grinding engine crankshafts for the last 2/3rd of the video?

Commentary and people in the video wearing PPE👍
Almost nothing fits the title of the video. Click bait!
Yes it does.
'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!!!!!!

This would be very hard to produce without computers and remarkable software. But it takes a human make it so.

AI narration should be illegal!
Showing there is rust even in a new ship!!

The Gerald R Ford is undetectable to radar??
Nothing about the machining. Sad.
The casting process never progresses
how about less time for your narration. It is really offputting.
It’s “ how a giant.” Or “how giant “
FIRE THE AI
Thanks for your comment. We will try more in next videos.
not done with computer design.. don't believe it
15/11 ths of a kilowatt? That's an odd way to express it.
It's more fluid than 1 & 4/11

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
