Abstract : An aircraft window clamping ring is used to hold an optical sensor window against an aircraft wall. The ring has a plurality of cantilevers having upper contacts that bear directly down on the window. Because of the flexibility in the vertical direction, thermal expansion is compensated for by movement of the cantilevers. Horizontal expansion of the window creates no additional stress because the upper contacts bear perpendicular to possible horizontal movement. The cantilevers can be designed to preload the window to take into account maximum thermal expansion.
