Abstract


Abstract: Aerial application is a critical component of modern agriculture, and it is crucial for aerial application of pesticides to be environmentally protective and efficacious.  The spray nozzles involved in the application process are a vital component in the precise and safe delivery of applied products.  This paper reviews and summarizes the state-of-the-art in aviation nozzle technology and the physical processes of nozzle atomization on manned platforms.  Highlights are two main aerial nozzle types along with their working principle, the factors that influence atomization performance and new technologies for reducing drift and enhancing application efficiency.  Moving forward, the research mainly focused on the development and evaluation of drift-reducing and variable-rate technologies, enhanced atomization models, the impacts of aerial tank mix adjuvants, and non-conventional application technologies (such as electrostatic or pulse-width modulation systems) are likely to have the most significant impact on the aerial application industry.  This review provides a summary of the history and advancements in nozzle technologies and encourages further development.

Keywords: aerial application, nozzle, droplet size, atomization performance, drift-reducing
