The invention relates to the technical field of artificial rainfall and discloses an artificial rainfall aircraft and method. The artificial rainfall aircraft adopted in the method comprises a multi-rotor craft, a dispenser 8 and aircraft bases 9. The lower portion of the multi-rotor craft is fixedly connected with the dispenser through a connecting board 7. The multiple folded aircraft bases 9 are arranged at the bottom of the dispenser. The dispenser is composed of transmitting devices evenly distributed in a rack 10 and an executing mechanism 11. Each transmitting device is composed of a transmitting pipe 12 and a silver iodide rod arranged in the transmitting pipe in a filling manner. The executing mechanism 11 controls the ignition time of the silver iodide rods. By the adoption of the artificial rainfall aircraft, a rainfall agent can be accurately dispensed to a rainfall region in a carpet manner to achieve an accurate rainfall purpose, the artificial rainfall aircraft can be folded as well so as to be conveniently transported, and the artificial rainfall aircraft further has the basic functions of vertical take-off and landing, hovering, advancing, backing, turning flight course planning, memorizing and the like.
