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.
