I think you should revisit this topic and study more of the fact that the particular shape of the seed may cause it to spin up faster than the three bladed rotor. The reason I say this is because when the seed first falls The air drag will cause the blade to go vertical and it will start to spin very rapidly which will cause centrifugal force to pull the blade out horizontally. Therefore I think that a single blade with the correct design will actually fall slower than a three blade design by a significant margin

The same kind of rotary effect happens when helicopter engines fail. We saw this in the Australian fires recently where a firefighting helicopter went down and the pilot walked away from the crash landing. People expect helicopters to go down like a rock, but unless they have rotor damage, or the pilot loses control, the fall causes the rotors to spin and slow the descent. It is called autorotation. The record for this was set in 1972 when French aviator Jean Boulet had an engine flameout at 40,814 feet and he was able to use autorotation to safely land the helicopter. Incidentally, that flight is still the highest that any helicopter has ever flown and the flameout is the reason no one else has tried to beat it. BTW, the American military has a decoration called the ‘broken wing’ for any pilot who successfully autorotates in an emergency and saves lives as a result.

Please do this

I haven't finished watching yet, but I just wanted to let you know something. I occasionally fly RC autogyros, and to save from breaking blades and hubs, we use soft balsa shear pins and one of our two points connecting the blade to the hub. The other being a bolt that allows for rotation, so when there's a blade strike, the sheer pin breaks, and the blade can fold back and hopefully not break.

In my final year at uni I had a very similar concept for slowing down payloads dropped from a UAS. The rotor would be tensioned on a wound spring to provide that initial spin once dropped and allow the payload to be dropped at a lower altitude without plummeting. Unfortunately it would have been heavier than parachutes and mass was at a premium to keep it below the 7kg limit. This was for the IMechE UAS Challenge by the way and well worth checking out if you haven't already. The design would also have changed the pitch of the rotors to benefit from auto-rotation, then use that momentum to produce a lot of lift nearer the ground. I'm really happy you made a video on this as it was something I obsessed over for the better part of a year. Great work!

In WW2, the U.S. Army used a single blade case, like a very large version the leaf shown in the video, to airdrop a vacuum tube radio without damage. The spinning case was less subject to wind drift allowing more accurate drops.

We tried putting one of these on a rocket in our latest video.... didn't go so well tho

its pretty obvious when you think about it because its using some of its potential energy to spin rather than using it all to fall.

As you were talking about this I envisioned a parachute, but different than the vortex one. I imagined one that was similar to a regular parachute, but with flaps that start of closed, until the pressure gets to a certain amount, then they open, causing it to spin, with some connector in the middle that allows the chute to spin, but not the cargo below it.

Nice drone, looks clean and simple!

To put things simply, it transfers the energy into spinning.

@AttilaAsztalos

4 жыл бұрын

That sounds like putting things too simply. Can't be just that. To avoid converting _all_ potential energy into kinetic energy after some arbitrary point (which would be freefall from that height) this thing would have to _continue_ converting _some_ part into rotation all the way as long as it's falling - however, that would have it spinning faster and faster all the time, which is simply not the case. More likely it immediately transfers on that "spinning" into air propelled downwards.

I wonder what a "parachute" that is 3d print everywhere BUT where the rotor is would do. . .

I like this video, its an easy idea to wrap your mind around idea but an interesting and relevant one, tested in simple and direct ways I noticed that the normal parachutes had a tendency to have a slight spin to them as well, interesting. One thing to talk about that I think is relevant is that the thing has to get a pretty good spin rate going to slow down, and at a certain point you might have to worry about nausea from the human in the parachute, or additional engineering complexity to make it so the chute can rotate freely without the attached body

i love this watching for second time on your vids i learn more

That's a major reason why people could never imploy auto rotation; along with the fact that people don't like to be spun at speeds, making any landing difficult if not impossible. You HAVE TO hit with your feet first, and collapse to distribute the force of impact, if you were incredibly dizzy, this would not be possible and you will end up with a broken leg.

There's limited potential energy from dropping something, spinning requires energy that would otherwise go to falling.

You could shape the parachute like one of those pinwheels that kids make out of paper for school projects. It might work better than the spinning parachute you made. Or, you may also want to try two counter-rotating spinning parachutes, or perhaps even four counter-rotating parachutes arranged in a square formation. This way there is no net spinning force imparted on the payload.

The eaten by a bird and then later crapped out is stellar distancing method.

FYI, the design of a sycamore seed (and its rotation characteristics) have been used for 40+ years in the design of Maximum Time Aloft (MTA) boomerangs. By having a shape like a hockey stick, there is a differential lift that makes the boomerang fly upwards, somewhat along an exponential curve that circumscribes an inverted cone (near enough). So, when the 'rang is released (spinning vertically about a horizontal, transverse axis), the precession of the spinning 'rang makes it 'lay over' so by the time it's at the top of its flight (30-50m), it's spinning about a vertical axis, much like a sycamore seed. Placing weights around the centre of gravity of the boomerang shape also affects the rate of 'layover' (which is like the 'bias' of the seed/'feather' combination -- we're talking about modifying the moment of inertia here). I haven't thrown competitively for over 20 years now.. but back in the '80s/'90s it was relatively easy to get 50m 'stabilized' flying heights and 60+ second flight times for a 'rang that's something over 35cm across its tips. If you were 'lucky'(!?), you could get the 'rang into a thermal and with a stable spin, it could rise and fall a handful of times so 200+ second flight times were possible. Rotary wing dynamics is such a *fun* study... (errr, ... yeah). :) Edit: An old reference, f'sure... but it shows when I had the Australian record for MTA flight (with a return within a 50m radiuscircle) - I was kinda disappointed that it took more than 10 years for the record to be broken (!) ... www.boomerangpassion.com/competition/records/
