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
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
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.
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... 😞
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.
@@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 😅.
Hallo Christian, habe deine handwerkskunst auf deinem RU-vid 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 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?
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.
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.
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
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.
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
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👍👍😊🙏
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.
