The spray characteristics of drone sprayers are significantly influenced by the downwash
airflow produced by Drone multi-rotors. The present study aimed to study the influence of
downwash airflow and the operational parameters of Drone sprayer, viz., flight height, travel
speed, rotor configuration, payload and wind velocity on the spray distribution pattern for
boom sprayer attachment to Drone. The boom type sprayer consisted of four numbers of flat
fan nozzles placed at three different spacing viz., 30, 45 and 60 cm between each nozzle …
