    Abstract: The invention relates to drones for a combat game, preferably a drone (1) and at least one opponent drone (2), said drones comprising radio control means, signal transmitters, receivers, and cameras. The invention further relates to a system for a combat game, the system comprising a drone (1) comprising a weapon (3), and at least one opponent drone (2) comprising an opponent weapon (4), wherein the drones are equipped with radio control means, signal transmitters, signal receivers and cameras. The drones and the system are characterised in that the opponent signal transmitters (6) disposed on the opponent drone (2) and on an opponent weapon (4) are in control connection, via a control unit (15) of the drone (1), with the signal receivers (7) of the drone (1), the connection being adapted for transmitting the signals generated through targeting by an opponent player (26) utilizing a display (22) of the opponent player as control means, and for controlling the rotational speed, position, and operation of the light source (9), sound source (11), and smoke source (13) disposed on the drone (1), and the motors (19) of the propellers (17) thereof, and in that the signal transmitters (5) disposed on the drone (1) and on a weapon (3) are in control connection, via a control unit (16) of the opponent drone (2), with the opponent signal receivers (8) of the opponent drone (2), the connection being adapted for transmitting the signals generated through targeting by a player (25) utilizing a player's display (21) as control means, and for controlling the rotational speed, position, and operation of the opponent light source (10), opponent sound source (12), and opponent smoke source (14) disposed on the opponent drone (2), and the opponent motors (20) of the opponent propellers (18) thereof.

    Abstract: Rotor noise cancellation through the use of mechanical means for a personal aerial drone vehicle. Active noise cancellation is achieved by creating an antiphase amplitude wave by modulation of the propeller blades, by utilizing embedded magnets through an electromagnetic coil encircling the propeller blades. A noise level sensor signals the rotor control system to adjust the frequency of the electromagnetic field surrounding the rotor and control the speed of the rotor. An additional method comprises of incorporating a phase lock loop within the control system configured to determine the frequencies corresponding to the rotors and generate corrective audio signals to achieve active noise cancellation.
