ABSTRACT:
A method and system for the abatement of fog in a designated air space over an aircraft approach zone and runway, consisting of gapped air jets laden with electrically charged droplets of low mobility, a ground corona guard in the form of a shallow water-and-oil basin, and a charged-collector-drops emitting device on the ground, arranged in such a manner that the low-mobility charged droplets blown aloft by the air jets form a virtual electrode suspended at appropriate height above the ground, toward which the oppositely charged high-mobility collector drops move, thereby collecting the neutral fog drops in their paths. The perforation ratio of the gapped air jet array is chosen such that the wind flux which penetrates the jet array is substantially equal to the entrainment flux at the lee side of the jets, thereby providing for a virtual canopy over the spatial region in which the fog is to be abated. A corona guard prevents neutralization of the collective electric field set up by the charged droplets blown aloft by the air jets, and also prevents premature neutralization of these droplets.
