I don't have $420 :(

[@AH-gt7my]

I am very impressed with your ability to make a job that is so detailed in the manufacturing process, it's amazingly good

[@savree-3d]

Thank you very much!

[@WanJae42]

Excellent stuff! I assisted (held tools) with the overhaul of a C130 (Hercules) prop when I was small, and never fully internalized the mechanism despite having seen it in bits. It shares a similar concept.

[@hanleypc]

Very interesting, you can apply reverse thrust allot more quickly than slowing down your main shaft and reversing rotation. Good video.

[@savree-3d]

Thanks

Thanks for the info I had a hard time understanding how hydraulic lines were working on something that’s rotating never realized its more like a shaft inside a shaft.

Thanks Sir... Explained very well... Subscribed for more videos...

[@nitroxssss]

Thanks and i have a question. Does the control rod inside the shaft rotates with the shaft or not?

[@vardhaniattili4724]

Nice

[@MrRoan00]

Nice vid! Got curious how the fluid gets in to the shaft, I suppose the whole assembly is rotating together :)

[@savree-3d]

Will have a look at doing a video about it.

[@65gtotrips]

I have the same exact question; As in constant speed variable pitch aircraft propellers. The one article I read states the fluid comes from inside the crankshaft, but there’s got to be a pump and a sump somewhere.

[@pankajdhaka4544]

How is the hydraulic oil supplied to the tube?

[@user-jq6ey9xk8w]

its very good tanks how application used to design animation?

good one!

[@savree-3d]

Thanks!

[@user-tg4nu5mq9g]

Hello John What kind of sensor is used for measuring the pitch ?

[@imranla3619]

Hi, may I know what is the best software to use for propeller designing ?

[@verminer7]

Could you please do another type or design of cpp?

[@wyskass861]

Good animation of the actuation, but the one thing I can't seem to find an understanding for is, how you connect hydraulic pressure lines from outside the prop shaft into the spinning interior and on two concentric levels.

[@cougarten]

what rotates and what doesn't, how does it seal in between?

[@boris2997]

Who ever invented that is a genius,

[@eflaaten]

Nice! What software is this?

[@chandrashakhernogia8712]

Sir what is the feedback for electrical signal control in this CPP

[@canunal6048]

İs this one action or double acting piston ?

[@musasky2274]

How can i get this propeller?

[@isimioluwasuyi-dw4ht]

That rotation bit on changing the pitch is Propriety information. Right? 🙂

[@thesmallterror]

How does the hydraulic fluid get into the shaft? Isn't the shaft really long? Is it pumped in a hundred feet away at the engine?

[@savree-3d]

Will plan a video for this.

[@savree-3d]

It's planned!

[@ekorobianto8408]

WOW, what's name aplication ?

[@meridianhopper1315]

In forward motion, which pitch is the most efficient? Shallow pitch or a greater angle of attack? I hear conflicting answers from others.

[@abnormaalz]

The propeller blade is optimized for a certain Angle of Attack. This is the angle between the direction of the water flowing into the leading edge of the blade and the chord line (google angle of attack for a better explanation). The optimal AoA depends on the shape of the blade. The actual AoA depends on the speed of the ship moving through the water, the rotational speed of the shaft, and, of course, the pitch of the propeller blades. There is no single optimal pitch setting that can be used at all times, but there is a single optimal AoA.

[@naveenharish7151]

Please explain flash point and fire point

[@savree-3d]

Will add it to 'the list'. Nice Peeky Blinders avatar.

[@larrys1996]

I have a better way to change pitch, can interface with electronics and act like automatic transmission. you did very well
