Observation. It seems that the contra-rotor helicopters’ rotors are separated further apart. It seems as though yours are really close together. How does distance affect rotor wash? How does rotor blade design compare to the standard helicopter blade? It occurs to me that blade design history, both with single and contra-rotor machines, might guide current applications.
Seems premature to give up this guickly.its facinating to watch.also did you think of shortening the cables on the single rotor the install a low tension sppring in the cable ends, to effect a small amount of flapping effect?
This is awesome. You could get some flexible gardening or flowerbed edging to put on the outside of the wooden blocks to prevent the small indentations you spoke of. Or use stacked plywood.
It looks a little bit terrifying, at least in a video. Not sure what is the tension there, but I would maybe add a little bit of support to prevent tube from popping out.
Nice. I suggest you don't pull the tubing from the center. Use some pulleys that can pull at the 90 degree position at the near radius. Install guides to separate the two tubes as they approach each other. They will cross the midway under tension but can be easily aligned into a circular shape as they are released from tension.
Don't give up with levitator! And check out Angel Aerial Systems, they are building a drone with a 2 hour flight time with the exact same idea! Love your channel, keep making the videos!
wonderful idea very much like steam bending wood If your line starts deforming the inner wall of the tube try lubricating the the line with paraffin. If you need to weld the tube be sure to clean them very well with alcohol or acetone.
That is awesome! I have garden foil tent, however original tubes for its structure ware destroyed by wind and rain. I was planning for some time to buy beefier tubes and replace damaged ones, but wondered how to bend them nicely.. And that will work - THANK YOU!!
Very good idea, seems to work nicely. As others have mentioned, a standard way is to fill it with sand. One alternative to sand is salt, which has the advantage that if the filling is difficult to get out, then salt can be dissolved and totally rinsed out with water. But your idea seems better for simple convex shapes, like circles.
@EngelsCoachShop uses a comparable setup for steambending wood only with an additional flexible backing strip to keep the bend object under compression along the bend line. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b9UPihp04xY.htmlfeature=shared&t=337 I think that in your setup the string serves the same purpose. In the beginning of the bend when the friction around the edge on the end of the tube is high it keeps the inner bendline under compression. In any case, looks like a very clean bend. Thanks for sharing!
