Abstract
An aircraft windshield transparency includes a base frame defining an opening into which an inboard-positioned transparency is mounted with at least one outboard-positioned transparency and an interlayer between the two transparencies. The interlayer exhibits a stronger adhesion to the outboard transparency than to the inboard transparency. The peripheries of the outboard transparency and interlayer carry a means which functions to expose a groove penetrating to the surface of the inboard transparency such that the outboard transparency and interlayer may be removed and the inboard transparency thereafter functions as the primary windshield transparency of the aircraft.
Claims8
A transparency for an aircraft windshield and the like comprising in combination:
- a base frame defining an opening and adapted for receiving transparency material therein:
- a first transparency mounted at an inboard position with the base frame;
- at least one additional transparency mounted at an outboard position within the base frame with respect to the first transparency;
- an interlayer between the transparencies characterized by exhibiting a stronger adhesion to the outboard transparency than to an inboard transparency;
- and
- means associated with the outboard transparency and with the interlayer, said means positioned within a groove which is cut peripherally about and within the opening defined by the base frame and which penetrates through the outboard transparency and interlayer to the surface of an inboard transparency, said means maintained within the groove by a sealant material and which may effect cutting through the sealant to expose the groove to the surface of an inboard transparency and permit removal of the outboard transparency and interlayer from within the opening defined by the base frame without otherwise demounting them from the base frame such that an inboard transparency is exposed to function as the outboard windshield transparency of the aircraft.
A windshield for an aircraft and the like comprising at least one pair of transparencies mounted within a window framework and an interlayer material between them, the interlayer material exhibiting a stronger adhesion to a transparency that is positioned outboardly within the framework than to a transparency that is positioned inboardly within the framework and a means associated with the outboardly-positioned transparency and interlayer material to expose a peripheral groove penetrating to, but not including, the inboardly-positioned transparency such that the outboardly-positioned transparency and interlayer material may be removed from the window framework and thus expose the inboardly-positioned transparency.
