The USDA’s Aerial Application Technology team developed this app, which allows aerial applicators to easily predict spray droplet size parameters based on their specific setup.
Potential Uses/ Testimonial:
Select from the 19 nozzle models available for use, including 10 nozzles for fixed-wing aircraft and 9 for helicopters. Calculate results based on variable airspeed ranges. Spray droplet size is based on the following four factors: nozzle orifice size, nozzle orientation, spray pressure and airspeed. These models have been available for several years as a series of downloadable spreadsheets. This app has utilized those spreadsheets to make them more mobile and with a streamlined interface. Users are able to review, save and share results as needed.
