Settings Parameters for Aerial Pesticides Application Using Gyroplane

Abstract

The operational effectivity of pesticide application on small areas of forests (<5 ha) could be improved e.g. by using gyroplanes. The gyroplane is powered by standard automotive fuel, and can be operated without airport infrastructure. For safe and efficient use of such technology an elaboration of working settings is needed. Three most widely used insecticides for protection of Polish forests were tested. In the conducted study new applications parameters (forward speed, flow rate) adapted to gyroplane were used. The rotating atomisers AU 7000 were adapted to gyroplane, to receive the application of insecticides, similar to quality received by aircraft. Additionally, the same dose rates of tank mixes were tested, but for application speed optimized for gyroplane (100 km/h).

Optimization of variables for maximizing efficacy and efficiency in aerial spray application to cotton using unmanned aerial systems

“…Efficacy and efficiency of aerial spraying are significantly influenced by spraying application parameters (atomizer or nozzle type, spray pressure, flight altitude and speed) [13] , the physical and chemical properties of the tank mix [14] and the meteorological conditions such as air temperature, relative humidity, wind velocity and direction [15] . Hewitt et al [16] have shown the relative effects of the nozzle and application parameters compared to the tank mix physical properties in affecting the size spectrum of the droplets in sprays applied by air.…”
