Flying object, flying object system, and method for painting object to be painted

A flying object comprising:

• a flying object body;
• a blade that enables the flying object body to fly;
• a paint ejection mechanism that ejects paint in a first direction at a first discharge rate;
• a fluid ejection mechanism that ejects a fluid in a second direction differing from the first direction by 90 degrees or more at a second discharge rate, wherein the second discharge rate is determined based on the first direction, the first discharge rate, and the second direction, such that flight of the flying object is stabilized;
• and
• a nozzle provided in a lower portion of the flying object body,
• wherein the paint ejection mechanism includes a first ejection port provided at one end of the nozzle, and the fluid ejection mechanism includes a second ejection port provided at the other end of the nozzle;
• wherein the one end of the nozzle and the other end of the nozzle are disposed outside of outer ends of the flying object body and outside of a rotational axis of the blade;
• and
• wherein a bottom surface of a lower portion of the nozzle is provided with a paint supply port configured to receive the paint supplied to the flying object from a paint supply container that is external to the flying object, a fluid supply port configured to receive the fluid supplied to the flying object from a fluid supply container that is external to the flying object, a first gas supply port configured to receive a first gas supplied to the flying object from a first air compressor that is external to the flying object to eject the paint from the first ejection port, and a second gas supply port configured to receive a second gas supplied to the flying object from a second air compressor that is external to the flying object to eject the fluid from the second ejection port.
