Title: DRUG SPREADING DRONE
Abstract:
[Problem] To provide a drug spreading drone (unmanned aircraft) which uses a simple construction to minimize scattering of a drug outside an agricultural field, without additional equipment or complex control. [Solution] Provided is a drug spreading drone which is provided with a drug spreading nozzle and a rotor (preferably a two-stage rotor), wherein the airflow of the rotor is actively utilized for spreading by positioning the drug spreading nozzle on the underside of the rotor, below a circular region which is centered at a point offset a certain distance to the rear, in the direction of travel, of an axis of rotation of the rotor and which has a radius of 90% of the radius of the rotor, and on a straight line at an angle of depression of approximately 60 degrees to the rear in the direction of travel from a horizontal line passing through the axis of rotation of the rotor. The position of the drug spreading nozzle may be made dynamically controllable.
