ABSTRACT:
A spray distribution system for discharging liquid pesticides and the like from a crop-spraying aircraft includes a double spray header arrangement. One main header extends beneath the wings of the aircraft and is fitted with spray discharge nozzles only beneath the aircraft wings. An auxiliary header extends beneath the aircraft engine, forward of the main boom, and is fitted with spray discharge nozzles beneath the aircraft body. The auxiliary boom is located far enough forward of the main header that it is out of the prop blast region. Each spray discharge nozzle emits liquid through an elongated discharge tube that substantially prevents misting. The spray discharge nozzles are each mounted on a downcomer conduit thus being located sufficiently below the aircraft wing so as to further reduce turbulence around the emitted liquid. The nozzles may be modified so as to accommodate more than one discharge tube.
