Abstract: An apparatus and method are disclosed for the aerial spraying of agricultural chemicals with improved spray deposition and reduced drift. The spraying apparatus includes two oppositely charged sets of spray nozzles which may be fitted onto an aircraft. Both sets include one or more nozzles having spraying tips which produce a hollow cone spray pattern, and at least the tips of these nozzles are constructed of a substantially non-conducting material. Cylindrical electrodes are positioned concentric to the nozzle tips for inducing an electrostatic charge upon liquid spray emitted from the nozzles. The electrodes are in turn connected to high voltage power supplies, with the electrodes corresponding to the first nozzle set being connected to a power supply of opposite potential than the electrodes corresponding the second nozzle set. Consequently, the spray issuing from the nozzle sets will be oppositely charged. For effective electrostatic aerial spraying from an aircraft, the corona discharge of the airframe must be substantially near zero. In practice, this is accomplished by maintaining equal mass flow rates of the fluid dispensed from each nozzle set, and adjusting the charging voltage of the each power supply such that the fluids provided to each nozzle set have equal charge to mass ratios which are at a level of at least 0.8 mC/kg.

Abstract: An isolator system for an attachment to an electrostatic field sprayer discharging liquids having an electrostatic potential thereon comprising a series of spaced apart flat discs that shed water in both directions, and which are made of an insulating material and mounted concentrically on the attachment. The attachment has a length that extends substantially vertically downward, and said discs are spaced apart in vertical direction. The discs are graduated in size with the smallest disc on the bottom, and any discs above the bottom disc are of larger diameter than the next adjacent lower disc.

Abstract: An apparatus is disclosed suitable for electrostatic spraying from fixed wing aircraft. The apparatus includes a linear electrostatic spraying nozzle 2 and electrodes 4 placed near the nozzle's spraying edge to intensify the electric field strength at the spraying edge sufficiently to produce ligaments of the liquid to be sprayed from the spraying edge. In order that the airstream due to the aircraft's movement does not destroy the ligamets, the sprayhead and the electrodes are positioned so that part of the airstream flows between them. The spray head and the electrodes are so shaped and positioned that when directed to spray in substantially the same direction as the airstream, a turbulence free wake is left in the region of the ligaments.

Abstract: Aerial spraying apparatus includes two sets of nozzles located at spaced locations on an aircraft. Each nozzle has an electrode associated with it to induce a charge on the cloud of droplets issuing from the nozzle. A high potential is maintained on each electrode by a power pack that induces an equal and opposite potential on the electrodes of each set. By virtue of the opposed polarity of the electrodes, the aircraft is maintained at a neutral potential. To prevent a potential being imposed due to spray being deposited on the electrodes, a pair of corona needles are provided to establish a leakage current and maintain the electrodes at the required potential. This prevents the system becoming imbalanced and a potential being established on the aircraft.
