Invisible Unmanned Aircraft

MattSparkes writes, "A Minnesota company, VeraTech, has applied for a patent on an unmanned drone that is nearly invisible to the naked eye. The Phantom Sentinel takes advantage of the phenomenon where fast moving objects appear as only a blur, so it fades out of view once it speeds up. This is achieved by rotating the entire craft. The center of gravity is in open air between two of the blade-like wings. There are some videos of a prototype in action on the VeraTech site." The company says you could get usable video of the terrain by processing the images from a spinning camera. One version of the drone is small enough to launch by throwing it like a boomerang. And it folds for travel.

Videos?

And what exactly would we not see there?

No it isn't invisible

but it is close.... Yet another misleading /. subject header.

The basic idea is that the plane flies by rotating and, just as a fan blade or propeller becomes close to invisible when spinning, this aircraft might too.

Of course visibility to the naked eye is only a very small part of invisibility. This thing probably sticks out like dogs balls on radar.

This looks designed to be robotic, so don't worry about the pilot.

And, while not completely invisible, it has a much lower visual signature than anything else of comperable size. I'm just not quite sure what the use is: it probably has a higher radar cross-section, so it's fairly useless as a spy-plane. The only thing you are really hiding from are people. Or civilians. Might be usefull as a close-rage spybot on a battlefield, but anybody with smart weapons can see and hit it quickly.

Waste of money...

Military drones fly at extremely high altitudes. Thus, they don't have to worry about being spotted by the naked eye. They're also very small, so they have a little tiney-tiny radar cross-section, too -- making them look like a bird on most radar screens.

Basically, this sounds overly-complicated and expensive to implement and is utterly unneeded. So... the military may well go for it! But it's still completely retarded.
