Abstract
Abstract A spray boom for aircraft involving an elongate reservoir having the exterior shape of an air foil designed to minimize drag and assist in the lifting of the aircraft. The reservoir is interiorly divided into a plurality of separate compartments, each of which is sealed from one another and each of which is capable of handling a different type of material such as liquids, powders, granules, or even gases, if so desired. These compartments extend the full length of the boom and each of the compartments is provided with its own discharge nozzle whereby the contents of each or any of the compartments can be individually discharged therefrom along the entire length of the boom so that the contents of each compartment can be sprayed across the entire spray pattern of the aircraft.
