This is a customer project I am working on right now. The whole propulsion system will be installed in a 1:4 Pilatus PC-6. Planned wingspan: 4m MTOW: 25Kg
Interesting mechanism translation at the front. Kind of reminds me of older telescoping mechanisms for long range camera lenses. Same kind of idea, only those operate only on the cylinder wall of the lens, so things are a bit more compact.
Nice stuff. You got the capitalization of kW correct in your video, but your title I was looking at before I started the video had it reversed. Nice devices you create. I thought I was going to mention the Kw kW thing, then I saw where you already got it right. Of course, most lay persons will read it as kilowatts in either case for the most part. Not digging on you. It was just a mention.
Curious why client wants a variable pitch prop on an electric motor? Is it for the realistic looks of a real thing? In theory, you shouldn't need a variable propeller on an RPM scalable motor. They are only used on fuel powered engines due to the the powerplant RPM limitations and the power curve. Otherwise, excellent craftsmanship and a beautiful project!
Thanks! One thing is the sound but with variable pitch you can brake or slow down on ground and perform very steep, slow descents in the air - just like the real plane does.
The control forces will be less than 50N. The key is balancing the blade holder and blade assembly around their rotational axis. I have already made a 4kW variable pitch propeller. It can be controlled by a 10Kg Servo no problem.
@@christiansprojects-cgmanuf1426 Your work is amazing! in any case since I saw what you were doing I installed fusion360. So far I draw more in 2D or sometimes in 3D with Freecad but of course Fusion is clearly much better! Now I have to work on it and hope to be able to do what I want with 😅.
Any Chance to make a 3 bladed 26 inch like this. But for a Twin with 2 BX-120 Kolm engines? I will only need the prop to feather in case of an engine failure
I really like your videos... actually they are very practical and also technical!! These days I work on my VTOL with coaxial blades with swashplate blade control mechanism. Last night it worked for first time and I test it for first engine run up... use some of you video for my job👍👍😊🙏
Very interesting. What is the advantage of a cp prop setup? How much does a motor that size cost without the upgraded mechanism? Thank you for sharing.
Я тоже думал об этом в самом начале. Но поскольку усилия приведения в действие всей механики компенсируются противовесами на держателях лезвий, сервоприводу требуется очень небольшое усилие. Пока все работает следующим образом.
Hi again. Loving your videos. What is the smallest scale you can make this variable pitch propeller system in? Would it be possible for 8" to 9" props?
Hallo Christian, habe deine handwerkskunst auf deinem RUclips channel gesehen. Allllller größten Respekt! sag mal wie weit ist dein neues variable pitch prop Projekt? Hab auch eine vq pc6 mit einem 6374 und würde die gerne wie deine mit vp ausstatten. handwerklich für mich kein thema, währe es möglich nähere Infos zu deinem pc6 prop zu kriegen? Fotos von der Mechanik, Details, oder Pläne? Würde es sehr gerne bauen. Gruss Vitali
Why would you want to have variability in the pitch of the prop when you can change the speed of the motor so easily? (If you like robots, I'm building a 2 legged full size walking robot on my channel. Check out it out and let me know what you think thanks)
Hi. These are carbon reinforced nylon blades from a guy called Christian Ramoser. They are originally designed to fit his hubs but they can be modified to fit hubs of your own design. Here, "Propellergrösse" means Propeller size. There are 6 different hub sizes and various blade designs and lenghts: www.ramoser.de/home_d/varioprop_d/varioprop_d.html
Was ist das klobige Ding zwischen hinterstem Stab-Ende und Kipphebeln??? Box mit sogenannten Druck-Nadellagern??? Der Stab dreht sich doch mit der Motor-Welle mit, oder??? Wenn da Nadellagern drinne sind, hab ich immer gedacht, das dieses Ding flach & rund sein sollte, aber nicht so klobig, also, bin ich durcheinander... 😞
That is really interesting in it. What is the name of the application you make your drawing and desgin on it. Does it able to work for big projects the concept
What about if he isn’t comfortable speaking in English? Maybe he just doesn’t want to. Can’t you just be grateful that he took the time share his amazing project with us.
@@DMSparky Exactly Right Sir, Christian has us in awe of his talent but there is always someone (8%) Still Complain about something, He should learn the Volume Knob and keep to him self
hi bro, we are making the drone for the purpose of main project, we need a help from you, design specifications of contra rotating propeller drone for carrying loads bro, and also we need a design also bro. and also we want how you designed a drone in fusion 360, please give your mail bro.
"It is stable during high Revolutions per minute, due to the adjustable track sliding sleeves."👍
I hope you are successful with this project. Very interesting,
Thanks! I am manufacturing the parts right now. There will be a new video soon.
very nice work thanks for posting and sharing
Awesome work, would love to see a flight and function video
Thanks! There will definitly be such a video but it will take some time. The first parts will probably be manufactured in spring 2021.

Bravo......ok I know u thinking rc........they make a base speaker with variable pitch blades........cheers

SUPER! Really love! Congrats... I am super happy!
i would stick a centrifugal governor on it to control the pitch instead of using a servo. nice design
Gorgeous! Very nice engineering!

That servo needs to be huge. Because it's gonna take a huge load.

Would be interested if you would do the same for a gasoline engine ... DLE xyz for example.
Thank you for the video. Fantastic topic. The music on the video is too loud and annoying. Hearing you describe stuff would be so much better.
Perfect👍👍

Вместо рулевой машинки, лучше поставить электромотор с винтовым штоком, надёжней будет.

Gibt es eine kleine Serienanfertigung?
Vielen Dank! Das steht noch in den Sternen. Geplant habe ich etwas... Aber dafür muss ich diesen Frühling erstmal meine Werkstatt etwas aufrüsten.
@@christiansprojects-cgmanuf1426
Ich wäre auf jeden Fall daran sehr interessiert 😊😍

Bitte. Bitte, lass diese Musik weg, das ist unglaublich nervig. Tolles Projekt!
manche Kommentare sind auch nervig :D oder manche C Musiker.
There is a Volume slider you know.
Did you get to make this prop?
Nice👍🇲🇬

Everything is super. But the blades are very confusing. They don't have to be flat. The angular velocity is different along the length of the blade.
The blades are only there for the looks of it. They will have a proper airfoil profile.
Ret lækkert❤️❤️❤️🏁🇩🇰
Have you finished this project ? I am interested in this for my PC6. Do you want to give me a price ?
Needs thrust bearings at the base of the blade too...
There are some ;)
I see the motor is rated at 9kw max power. What max trust do you expect? 30kg?
It will be in the 25Kg range I hope. Maybe slightly more at zero speed due to the adjustable blades.
Please show us more about the PC-6, what an amazing plane! : D
What CAD package is that?
Hi. It's Fusion 360.
Amazing good jod
R you taking orders?
If so,
I am very interested in a contra rotating pusher prop. for my project
Hi. Thank you for your request. At the moment, I can't take any orders. Sorry!
you should upload more and more video
That is really interesting in it.

Autodesk Fusion 360

You are open to join big project.
Do you sell these I'll by one
Good
Help me please
That's awesome, could you please send me your designs? it's important for my project
Hi, thank you but I want to keep the design for my own purposes. I hope you understand.
Baue mir bitte einen 6 Zoll prop VPP quadcopter für 3D mode FPV freestyle. Muss extrem leicht sein und stabil. :D Beste Grüße aus Luxemburg.
No reverse pitch? 😋
In a small RC, probably not the best idea.
can you share the CAD file
I won't share the files as there might be further projects based on them in the future, sorry.
He can share it for free... or become rich by selling it. What would you choose? I'll would choose being rich ;D
good grief dude! ditch that sorry ass music..
I don’t like the music but don’t really care when I’m focused on the actual to to focus on... the design process.
@@stevenm3914 the idiotic thought, that anyone would want to hear that shit whilst watching, just blows my mind.
Spielerei
Forget the terrible music. How about a narrative of how it works instead.
What about if he isn’t comfortable speaking in English? Maybe he just doesn’t want to. Can’t you just be grateful that he took the time share his amazing project with us.
