A series of dispersal nozzles is placed along the wing of an airplane near the hinge line of its edge flap which extends virtually from wing-root to wing-tip and is made up of numerous individual spanwise flap segments. Adjacent flap segments deflect in opposite directions so that a discontinuity exists in the trailing edge and, locally, high turbulence results. By placing the nozzles in this region, and ejecting the dispersants at these points, rapid and controlled distribution of these dispersants is made. This trailing edge flap arrangement is also us...
An aerial dispersal system for the distribution of chemicals from an aircraft having a pair of fixed wings comprising: a segmented trailing edge on at least one of said wings, the individual segments of which are hinged at and along a common line; a nozzle mounted on and carried by said at least one wing at each of the adjacent edges of said segments, each said nozzle being located forward of said common hinge line and facing in an aft direction; a source of dispersant; ducting between said dispersant source and each said nozzle; a control connected in s...
