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.
@@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.
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.
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.
'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?
Such a well-done video, congrats!
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.
Wow ! Didn't think I'd watch the whole video !
Brilliant commentary and information.
Hardly.

Shipment is the right word for a propeller...
good stuff 👍

Commentary and people in the video wearing PPE👍
This would be very hard to produce without computers and remarkable software. But it takes a human make it so.
The casting process never progresses
Nothing about the machining. Sad.

FIRE THE AI
Thanks for your comment. We will try more in next videos.
It’s “ how a giant.” Or “how giant “
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

現在有能力製作螺旋槳的木模技術人才越來越少了。慢慢由CNC製作木模來取代。
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
