Internal fluid cooled window assembly

摘要

An interceptor missile including an infrared radiation detection subsystem and a window assembly in the hull of the missile optically coupled to the infrared radiation detection subsystem. The window assembly includes an inner window, an outer window, and a support subsystem between the inner and the outer windows defining a plurality of infrared transparent fluid flow cooling channels between the inner and outer windows. A source of fluid coupled to the cooling channels for cooling the outer window without adversely affecting the optical properties of either window.
