ABSTRACT:
An apparatus for spraying liquids from a vehicle, suitably an aircraft or other airborne vehicle. The apparatus includes at least two sprayheads, each having adjacent thereto an associated electrode or an associated electrically conducting or semiconducting part of the vehicle. A generator applies potentials to the sprayheads and to the electrodes or conducting or semiconducting parts of the vehicle so that an intense electrical field is developed between the liquid which emerges from each sprayhead and the adjacent electrode or part. The intensity of each field is sufficient to atomise the emerging liquid. The polarities of the applied potentials are such that liquid emerging from one sprayhead is charged positively while liquid emerging from the other sprayhead is charged negatively. Connections to the generator are such that electrical current flows from a target to the generator via spraying liquid and one of the sprayheads and then back to the target via the generator, the other sprayhead and liquid emerging from that other sprayhead.
