An aircraft window assembly (10) includes a first panel (12) having a first surface (14) and a second surface (16). In a first state in which there is no pressure difference between the first surface (14) and the second surface (16), the first panel (12) has a cross-sectional shape selected from pla
An aircraft window assembly (10) includes a first panel (12) having a first surface (14) and a second surface (16). In a first state in which there is no pressure difference between the first surface (14) and the second surface (16), the first panel (12) has a cross-sectional shape selected from planar, outwardly convex, or inwardly convex. In a second state in which there is a pressure difference between first surface (14) and the second surface (16), the first panel (12) has an outwardly convex cross-sectional shape.

1. A deformable aircraft window assembly, comprising: a cast-to-shape polyurethane first panel having an outwardly-facing first surface and a second surface, wherein in a first state in which there is no pressure difference between the first surface and the second surface the first panel has a first cross-sectional shape, and wherein in a second state in which a cabin of an aircraft is pressurized and the aircraft is at a cruising altitude so that there is a pressure difference between the first surface and the second surface, the first panel has an outwardly convex shape;a second panel spaced from the first panel; anda functional coating positioned on one or more of the first and the second surface of the first panel,wherein the functional coating comprises a gradient coating having a thickness that varies across a width of the gradient coating, such that the gradient coating is thicker at a periphery of the first panel and thinner toward a center of the first panel, the gradient coating being configured to counteract a lensing effect caused by deformation of the first panel when the first panel is in one or more of the first state and the second state,wherein the first cross-sectional shape of the first panel is selected from the group consisting of planar and outwardly convex, andwherein the first panel is an outer panel with an outer surface defining an outer fuselage contour when in the second state. 2. The window assembly of claim 1, wherein the second panel is a cast-to-shape polyurethane panel. 3. The window assembly of claim 1, wherein the first panel is configured to engage a frame such that the outer surface of the first panel is offset from an outer contour of an aircraft fuselage. 4. The window assembly of claim 1, wherein the first cross-sectional shape of the first panel is planar. 5. The window assembly of claim 1, wherein the first cross-sectional shape of the first panel is planar and the second panel has a planar cross-sectional shape. 6. The window assembly of claim 1, wherein the second panel includes at least one pressure equalization hole. 7. The window assembly of claim 1, wherein the first cross-sectional shape of one or more of the first panel and the second panel is planar. 8. The window assembly of claim 1, wherein a first cross-sectional shape of the second panel is inwardly convex. 9. The window assembly of claim 1, wherein the first panel comprises a cast-to-shape rabbeted edge engaging a groove in a seal. 10. The window assembly of claim 1, wherein the functional coating comprises a solar control coating comprising at least one infrared reflective metal layer. 11. The window assembly of claim 10, further comprising a protective coating over the solar control coating, wherein the protective coating is selected from the group consisting of a metal oxide coating and a polymeric coating. 12. The window assembly of claim 1, wherein the functional coating comprises at least one metal oxide layer. 13. The window assembly of claim 1, wherein the first panel comprises a cast-to-shape rabbeted edge and the functional coating further comprises at least one infrared reflective metal layer, the assembly further comprising: a seal having a groove, wherein the rabbeted edge of the first panel engages the groove; anda protective coating over the functional coating, wherein the protective coating is selected from the group consisting of a metal oxide coating and a polymeric coating. 14. A deformable aircraft window assembly, comprising: a cast-to-shape polyurethane first panel having an outwardly-facing first surface and a second surface, wherein in a first state in which there is no pressure difference between the first surface and the second surface the first panel has a planar cross-sectional shape, and wherein in a second state in which a cabin of an aircraft is pressurized and the aircraft is at a cruising altitude so that there is a pressure difference between the first surface and the second surface, the first panel has an outwardly convex shape;a second panel spaced from the first panel; anda functional coating positioned on one or more of the first and the second surface of the first panel,wherein the functional coating comprises a gradient coating having a thickness that varies across a width of the gradient coating, such that the gradient coating is thicker at a periphery of the first panel and thinner toward a center of the first panel, the gradient coating being configured to counteract a lensing effect caused by deformation of the first panel when the first panel is in one or more of the first state and the second state, andwherein the first panel is an outer panel with an outer surface defining an outer fuselage contour when in the second state.
