농업용 드론 분사 노즐 위치의 최적화

다국어 초록 (Multilingual Abstract)

Drones, which are autonomous flying machines range from large unmanned aerial vehicles (UAVs) flying thousands of kilometers to small vehicles flying in confined spaces, are utilized in carrying out a variety of operations including military tasks, search-and-rescue missions, reconnaissance, and load transportation. Much of the research related to these UAVs has concentrated on the autonomous control of UAV’s position, altitude, and attitude. Recently, the endurance is another issue in commercial applications. In addition to the control and endurance, a spray system is also important for an agricultural use. Although the spraying system has been well developed for agriculture, the design for an installation of the spraying nozzle on drones depends on designer’s experiences. In this study, a simulated spraying system having two blades and two nozzles was constructed to provide useful data for the design. Uniform spraying is required in an agricultural application, and the distance between nozzles is a major parameter for the uniformity of spraying. The spraying performance was measured with various nozzle distances from 0.8 to 1.2 m and it was evaluated by calculating variation coefficient with a digital image processing. The effective spraying width was 1622 m at the nozzle distance of 0.8 m. This study would be useful for a design of agricultural drones.
