Abstract: A hydrophobic coating and a method for applying such a coating to a surface of a substrate. The method includes applying a coating composition to the surface and heating the coated surface at a cure temperature from about 300° C. to about 600° C. for a time from about 2 hours to about 48 hours. The coating composition is applied to the surface by an application method selected from the group consisting of flowing, dipping, and spraying. The coating composition comprises a yttrium compound, an additive selected from the group consisting of a cerium compound and a dispersion of yttrium oxide nanoparticles, a water-soluble polymer, and a solvent solution of de-ionized water and a water-soluble alcohol.

Abstract: The present invention is embodied in a transparent, polyurethane laminate or multi-layer coating comprising a first transparent polyurethane layer, a middle conductive material layer disposed on the first transparent polyurethane layer, and a second transparent polyurethane layer disposed on the conductive layer. In one embodiment, the subject invention addresses the problem of static charge buildup on aircraft transparencies by allowing charge to drain through the second transparent polyurethane layer to the conductive material layer and then to the edge of the conductive material layer, where it is mated to the airframe. The present invention is also embodied in a method for forming a transparent polyurethane laminate on a transparent substrate and a method for forming a free-standing laminate.

Abstract: A low drag passenger-cabin window for use on an aircraft fuselage having a generally cylindrical shape, in which the as-manufactured geometry of the window is modified so that the shape of the window at cruise altitudes is aerodynamically optimized. The window comprises a pane of transparent material. The inner and outer surfaces of the peripheral portion of the pane as manufactured conform to a generally cylindrical shape, while the inner and outer surfaces of the medial portion of the pane as manufactured are depressed inwardly in a prescribed manner relative to the peripheral portion. The surfaces of the medial portion are adapted to deflect outwardly to conform to a generally cylindrical shape in response to a predetermined air pressure differential and/or a predetermined temperature gradient experienced at cruise altitude.

Abstract: The present invention is embodied in environmental seal technology incorporated into a double-paned window, the environmental seal technology comprising an inner desiccant seal and a structural spacer. The subject invention solves the problem of moisture between the window panes by keeping the internal gap dry using a desiccant system. The invention also incorporates a durable structural spacer that will not rupture under normal military vehicle loads and environmental conditions. The spacer is bonded to the window panes using pressure-sensitive adhesives, thus allowing for easy manufacture.
