I'm trying to figure out the pin blade helicopter.

So everybody knows these things, right?


Imagine if you had one of these, but cylindrical with the pins arranged along the shaft of the cylinder. Now imagine the pins could rapidly extend out to several yards and be controlled with a high degree of fidelity.

Now imagine we've commanded the pins to take the form of a helicopter rotor, extending and retracting in sequence to create the illusion of rotation.
Something like this:



Would our pin art helicopter rotor actually generate lift?

Mine was always too big to fit between the glass and the pins, but I imagine someone probably could.

a plane on a treadmill doesn't work because air isn't passing over/under the wings at differents speeds, which is what generates lift. similarly, the air in your thing is moving away from the extending pins radially to each pin and over the ends, so no differential in air pressure will occur to generate lift. sorry op, your not going anywahere

What if the pin assembly were covered by a sheet of an infinitely flexible substance that would allow the pins to more closely mimic the form of a helicopter blade?

How the gently caress does the whole long-rear end pin fit into the circle dealy in the middle? Some part of the pin is always going to be sticking out of one side or the other.

The pins are flaccid when inside the rotor hub, kind of like a coil of wire in a weed whacker. When they extend out, they become rigid and erect.

Well does a weed whacker go flying up into the clouds every time you fire it up?

If your weed whacker helicopter has to extend it's strings to take off and land, how is this saving any room? I'm assuming the whole point of this would be to save room, but it wouldn't, unless you're just trying to figure out a way to fit a helicopter in the back of your van.

I mean, what's the point of a helicopter with retracting rotors? It can't be to save space, since in order to take off or land it would have to have them all the way extended.

At least the plane on a runway would save space, and probably make aircraft carriers look a lot different.

Look I'll figure out how to use the drat thing all I'm asking from goons is whether it will work.
