[Merged] Ion drive aircraft

Not a rocket but an ionic wind for a drone with no moving parts.

Wow. I don't care if it has no practical applications for many years, that's just mind-blowingly cool.

Pretty much my view too

Giordano · 21st November 2018, 02:46 PM

Really neat. Although if widely adapted for drones, etc. would this not generate a lot of ozone pollution?

Bikewer · 22nd November 2018, 06:42 AM

Well, baby steps, anyway:

Small-scale demonstration of no-moving parts aircraft..

You can make these with wire and tin foil, there are instructions on youtube.

Of course, those ones need external power, the clever thing here is the very light power packs.

And scale.

Very cool, love where his inspiration came from.

Ah, yes, good point. I'd failed to note that - Five metres!

This needs to be turned into a Hoverboard ASAP!

There are drone aircraft that are powered by batteries. I wonder if these will be replaced by the new type of aircraft? They will be quieter.

I'm fairly sure that these new craft, driven as they are by pushing air across their lifting surfaces, can't hover like today's quad- and hex-copters can. Not that that's a requirement for all drones.

Ion drive sounds great until you see that isn't the power source, a battery creates the ions.

What am I missing?

I suggest you are missing nothing. The ions are generated and then accelerated backwards moving the plane forward.

As has been said before, nothing really. I should have said that it wasn't a spacecraft as ion drives are pretty mature technologies.

The Mythbusters tested one years ago, when they were investigating supposed antigravity devices found on the internet. One device floated in the air when connected to power, but didn't move when placed in a vacuum chamber, showing that it was actually ionizing the air to generate thrust.
