Research of crop-sprayer for dotted farmland using airflow induced by UAV

Typically, crop-sprayers are designed to be used at the farmland located far from residence. However, farmlands may be found often in the middle of residence. Crop-sprayer for such dotted farmland should be designed specifically not to distribute chemicals outside of the farmland. The purpose of this research is to figure out the optimum configuration for spraying chemicals for dotted farmland.
