The Bladeless Drone designed without blades, that makes it safer and quiet.
The Bladeless Drone by Edgar Herrera, is a Red Dot Design Concept Award winner.
It takes advantage of the headwind to generate downward flow.
The main propeller system positioned in the center, supports take-off and landing. The three other ones control the direction.
The two front propellers programed to work according the amount of headwind, can also rotate 20 degrees forward and backwards, for quicker maneuverability.
