The present invention relates to an unmanned aerial vehicle with multiple rotor blades, and the purpose of the present invention is to control the posture and the direction of the aerial vehicle without controlling the pitches of rotor blades to simplify a fuselage, not to have a large main rotor to prevent the occurrence of deadly accidents, and to overcome restriction on a coverage area for spray resulting from ascending air currents around the rotor blades. The unmanned aerial vehicle in the present invention for achieving the above purpose comprises a support which is arranged horizontally with respect to a forward direction of the fuselage; a plurality of motors which are installed horizontally in a long row with respect to the forward direction of the fuselage at front and rear portions of the support; a plurality of rotor blades which are connected to the output shaft of each motor to rotate; a motor drive control means which controls the rotation of the motor; and a battery which supplies power to operate each motor through the motor drive control means, wherein the motors are arranged at opposite positions of front and rear sides, and right and left sides to rotate in an opposite direction, the rotor blades positioned symmetrical to each other have pitches in the opposite directions rotate so that the rotor blades correspond to the rotational direction of the motors connected, and the motor drive control means controls electrical power supplied to each motor to have different electrical power according to the inputted operating signal so as to change the orientation of the fuselage. |
