Deflectors

[All Seeing Eye]

Ive thought up an idea for a type of deflector shield that could be built today.
You take an object and surround it with something similar to turbine fins like this:

the fins could be built with reinforced Titanium or Carbon nano tube stuff and be charged with electrons. When a missile is detected incoming the fins could be turned on at a fantastic speed, the missile will hit the blades/fins protecting the target and the fins wouldnt take too much damage as they constantly moving, when the missile detonates the fin it hit has already passed by.

The deflector could be scaled up and extra fins added as the millitary building or object being protected gets larger, this tech could be utilised to great effect for space travel.

how about the centrifugal force?

So you want to surround a ship (on the sea or in the air or space) with fins that spin around really fast?

How would that be possible, wouldn't work to well on the sea, wouldn't work in the air it'd interfere with lift, might work better in space

Two sets of fins both spinning in opposite directions.

Incoming missile hits the blades and explodes. OK.

Now you've not only got the shrapnel from the missile and its warhead still coming at you, but the shrapnel from the fins, too.

....so you double-kill yourself. Not good. Back to the drawing board.

Have you ever considered pursuing a degree in mechanical engineering, or physics?

I don't know about that. presumably these things are travelling pretty fast - so they are building up alot of energy that will be released upon contact with another object. Even dust in space causes damage when its travelling fast enough.

Maybe a better approach would be to have lots of expendable nanotube threads attached to your fins.

Still, your shield will still be quite vulnerable at the axis of rotation at the very least.

this scheme seems to offer little for all the overhead and trouble of setting it up.
For missles, a shotgun type active defense system would seem to be more efficient.
For particle beams or energy weapons...well you'd be pretty much toast anyway.

Hey, im just throwing some ideas out there, someones gotta do it.
