Stick your had outside the car going 60+. You can't breathe. Wouldn't that be the same here? There is a vacuum around the craft, so where would they get the air? I mean I am sure DARPA can figure it out.... Like all the other shit they did....and who will lose? We will.
whatever, the idea is good for surveilance drones
not so much for fighter drones that have to change course QUICK
you need rockets for that
How is it better than fan blades? How’s it compress the air to get enough velocity to move it? Seems like the electrical draw of a compressor is more than what we already have.
Internal fan like a bow thruster maybe, but small drones don’t need small adjustments. Large drones yes, when they are going 1000miles at speed like a rocket ship.
Just my take.
