Abstract
This invention relates to a porous panel for use principally, but not exclusively, for the distribution of a freezing point depressant liquid on an aircraft surface in order to provide protection against atmospheric icing. The panel comprises an outer porous sheet over the surface of which the fluid is to be distributed, a backing sheet of microporous material in contact with one side of the outer sheet, and a sheet of fluid impervious material which is spaced from the microporous sheet. The sheets may be secured to one another by adhesive bonding over a region located outwardly of the space. The outer sheet may be a porous material, a reinforced porous plastic material or a drilled sheet material.
Claims22
A porous panel for the distribution of fluid, comprising an outer sheet of porous material over the surface of which the fluid is to be distributed, a backing sheet of microporous material in contact with one side of the outer sheet, and a sheet of fluid impervious material which is spaced from the microporous sheet so that fluid can be introduced into the space between the microporous sheet and the impervious sheet whence it can pass through the porous sheets to the outer surface of the outer sheet, the sheets being secured to one another by adhesive bonding over a region located outwardly of the said space.
A porous panel for the distribution of fluid, comprising an outer sheet of porous material over the surface of which the fluid is to be distributed, the outer sheet comprising a porous, reinforced plastic composite material, a backing sheet in contact with one side of the outer sheet, the backing sheet comprising a porous plastic material having a lower porosity than the outer sheet, and a sheet of fluid impervious material spaced from the backing sheet so that fluid can be introduced into the space between the backing sheet and the impervious sheet whence it can pass through the porous sheets to the outer surface of the outer sheet.
A porous panel for distribution of a fluid, comprising an outer, front sheet having holes drilled therein, a back sheet which is impervious and is secured at a peripheral region to the front sheet and defines a cavity therewith, whereby fluid can be introduced into the cavity whence it can pass through the front sheet to the outer surface thereof.
