me too! Also, try to make it better, it is just an idea.

😁

SOLIDWORKS. After you design the parts you do the animation. If you know what you're doing it should take several hours.

John, @ 1:12 says it is a 30 pin. Did you watch the video ?

At 20,000+ rpm. This concept shows how this guy has no experience whatsoever. Another iPhone generation. By the way - show me thrust bearings that can work longer than 5 minutes without lubrication. Show me open thrust bearings that will go above 5,000 rpm.

yes, the very same it's happening in helicopters swashplate

Its for helicopter, called swash plate mechanism. It can easily handle 600-800rpm. If we put it on a plane it will turn into a suicide machine

@@AbdulMuntakim-j3nthen how should we control the angle of attack (pitch) of the propeller if we mount it on an airplane? Any other ideas ?

I hope you don't mean the blades changing pitch angle, cause they do. If you meant the whole prop rotating... I feel bad 😔

@@johnnygritz2065 yes. I really wanted to see it rotate.

Read description please.

I am not an expert on this and I cannot guarantee this would work. Maybe, try to make a search if someone has done it before. Best of luck to you.

AND ALSO HOW U MADE THIS ANIMATION

Hi, you post something 14 hours ago, I should be allowed to answer within a day or two. I saw your comment the first time you wrote it, and I am still trying to figure out, which part you do mean. Please have a look in the description, the files are all available for download. If you are a Soldworks user, the animation is included in the part. If you do not how to create animations in Solidworks, you should search for tutorials on the matter. Explaining is not possible through comment posting. First of all, there is nothing flexible on that assembly. Flexible is something that is able to bend, twist etc. If you mean the part that has a ball joint, that should get from a R/C helicopter main rotor. That mechanism on the helicopter, is also capable to rotate the blades. Also, search for videos on "rc helicopter main rotor assembly". Again, to ne honest, this video is missing a lot of details on many points. My experience comes from building remote controlled airplanes and helis and this is where this video is aimed at. I hope I helped a bit.

@@johnnygritz2065 thank u so much sir

It really helps me a lot

Hi, I don't know what happened with YT, I see double posts and I cannot find your previous comment on the ball joint so I can reply. Anyway, here's my answer. The flat part that has a hole for the ball joint, it has actually a sphere cut, NOT a cylinder cut, so the constraint is a concentric surface to surface mate. Hope this was helpful.

@@johnnygritz2065 sure sir, i will look on animation and thank you again

This was designed in Solidworks, maybe version 2016. Do you know how to use that program?

@@johnnygritz2065 yes I know

@@johnnygritz2065 yes we know

Can you help me in add assembly constrains and animation part

@@kashyapamble1452 Hi, files are available for download in the description.

Do you mean the propeller assebmly? Do you have any experience with remote control helicopters? What exactly do you want help with?

@@johnnygritz2065 im sorry i have responded late. Can u provide me ur mail so that i can message I have some doubts regarding how that front propeller assembly rotates

@@johnnygritz2065 can you please make a video on how you designed the propeller or can you send me some drawing of the propeller

Since many have asked for the design, I will soon make the file available for download. This one was created using solidworks. This one is a basic design and more detailing and improvement is needed. If someone is interested in making a working prototype, I would be happy to further help. Thank you all for your comments.

@@johnnygritz2065 we are making a design prototype for our minor project

lo siento, Yo no hablo español

Hi, www.laptopscreen.com/

Ha ha, sorry for that.

Thanks

Hi, as you saw there is a servo trying to keep the desired pitch of the prop blades. So, yes indeed, this isn't a how a CSP works. I have seen the videos. It was intended for a radio controlled aircraft. Also, this seems, as a rather stressful job for the servo to keep the desired pitch. A more sturdy mechanism is needed there. Thank you for your comment.

Thank you, Thank you, Thank you, :)

I hope it helps.

Thank you, that was the idea.

Thank you for you comment. This rough design is an idea of a mechanism constructed of aluminium and steel parts for a wooden prop about 25in in dia and spinning around 2500 rpm. I haven't work the math, I am thinking something like the parts of a rc heli main rotor where the main blades are attached to. Your comments are welcome.

i think to do it but forces are problem so i made some design that could be enought powerfull with ordinary materials. second problem is part of centrifugal force that pushes blades on low pitch and it is bigger as rpm rises , so must install counter weights but it starts to grow in dimensions, but i need it small. i have rc airplane with big flaps and i need variable pitch to be able for revers thrust after touch down because runway is short

@@makantahi3731 I am thinking more like a 50 -100 cc gas engine warbird airplane, where I can live with heavier stuff in my construction. Thanks for pointing out the change of pitch with more rpm. Definitely that servo alone won't be able to keep the blade pitch steady, I 'll keep that in mind. A mechanism with a leadscrew or something similar might be able to keep the pitch at the desired angle more efficiently. Thanks again for your comment.

for bigger things is easier, in shop can be found standard bearings that can hold high axial forces of blades and you can use normal size screws , for my plane it has to be about 2 mm screws, and bearings belovw10mm

@@makantahi3731 Could you modify the tail rotor of a Heli?

Hi, I don't know how to pm.

@@johnnygritz2065 do you have any social media accounts?

what oil, there is no oil, it works as on helicopter, mechanical movement of servo changes pitch through bearings and levers?

Parts seen at 0:54 are rotating, blue parts at 0:28 are rotating, while the part in the middle isn't. Notice all the bearings between the blue and middle parts. Also the bearings between it and the shaft shown just before it.

Thanks, practiced only a few hundred times :)

Hi, no laser cutting here. At least not yet. This machine cuts mostly wood. You can see a Makita router at some point. The blue DOW you see is used for fast cuts in order to get an idea of the final result without sacrificing wood. You can also see, two blue pipes for coolant for tool lubrication and cooling when the machine cuts aluminium. The big gear reduction is not that big. It is 3.75:1 It offers both torque and resolution. Even so, this machine manages rapids of 6000 mm / min (236 ipm).
