  • Superb video and job building the blades, very interesting and thanks for sharing it. Where did the blades balance in the chord-wise direction ? How close was the weight of each blade to each other? Not sure what adhesive you are using but I had an adhesive failure because I didn't etch prime or acid treat the aluminium. I was using 3M 2216 B/A adhesive, very expensive stuff but I didn't do a test sample. I suspect what you have done will be fine but you could add some trailing edge rivets just to be sure. Laminar flow separates way before the trialing edge so they won't make a difference to blade efficiency. Regards Ben

    @Ben-Dixey@Ben-Dixey Жыл бұрын

    • Thanks Ben. The chord-wise balance is close to 25% from leading edge. I had to replace some steel tubes (as requested in the plans) with aluminum tubes at the back side of the blade to get the chord-wise center of gravity more forward to the leading edge. Had planned to use rivets you can see the bore markings here: 21:57 but after bonding the blade the adhesive seems holding the trailing edges super strong so i wait with riveting and keep a eye on it how it will hold up after the first spin ups... I weighted the blades, they both show the same weight but my scale is only to 0.1kg exact... Cheers

    • @@ultralighthelicoptersounds good to me 👍 if you do have any trouble with higher than expected collective forces then you can always add springs to the mechanism, many helicopters have springs on the collective when the blades chord mass isn't perfect. Look forward to seeing some blade spinning. That's when the fun really starts.

  • This video came up in my feed somehow, but all hail the algorithm for it,,, I’ve watched a few a have a number of questions, but will wait until I get through the series as I’m sure it’ll become clearer. But you, my friend, are a madman,,, lol ;) I wish you the best on this journey, you appear to have a handle on it and know what you’re doing. Unfortunately, so many people through the magic of video editing and KZhead, may appear and come off as an engineer, far too many have earned their degree’s from the University of KZhead. I myself am not an engineer, though I play one on TV,,, (or YT),,,, ;) Tho through my 30 years of fabrication I have learned a thing or two and can speak confidently on a few things. Again, I haven’t made it far in the series yet, but did you have to address any heat-treating issues after welding any of the aluminum? With all your bell cranks pivoting on threaded / partially threaded stainless (it appears) fasteners, I would think that bushings of some sort would be appropriate? Some, from what I could see, are pivoting on the shank, but some appear to be riding on the threads, and with the constant cycling and vibrations,it would seem a bit safer a long wearing. Yet again, I’m no one but a stranger from the internet making an observation and offering you a well deserved "Atta’ Boy".

    • Better to use tip weights as inertia is a function of weight and speed. There’s not much speed at the root end of the blade. There are many areas of this helicopter where modern composites would provide superior strength, lightness, durability, or fatigue life. The rotor blades are just one of them. But it’s still a pleasure to watch it being built.

I am though surprised that the trailing edge skins are not mechanically fastened, relying on adhesive only, but being a free-edge and prone to flutter, at leat a rivet at the tip, and a few other radial places? The root of course is dealt with by the incidence control plate.
