Abstract
A window for a vehicle includes at least one transparent pane suspendable within a frame. The transparent pane comprises a deformable material. The transparent pane defines a first surface position h1 when not subjected to a pressure differential thereacross and a second surface position h2 when subject to the differential pressure thereacross. The first and second surface positions are defined with reference to an outside mold line. The first surface position h1 defines a reverse curvature with respect to the outside mold line. In response to the differential pressure ΔP, the second surface position h2 includes bulging of the transparent pane by a predetermined distance Δh. The frame is constructed to be positioned within the vehicle such that the transparent pane presents a surface, when subjected to the pressure differential ΔP, that is substantially consistent with the outside mold line of the vehicle.
