High Performance Cooled Seeker Window

Infrared (IR) windows operating in the environment experienced by endo-atmospheric interceptors are limited in performance by the high heat fluxes, temperatures, and pressures characteristic of these environments. Window temperature can exceed 900 C from exposure to the high heat fluxes and temperatures associated with hypersonic flight. Existing materials are limited by poor mechanical and optical performance at these temperatures. Mainstream proposes to design and build a cooled window optimized to operate in a high speed environment.A patent pending process will then be used to produce the window and cooling geometry. For the Phase I, Mainstream will design the cooled window, predict its performance, and demonstrate the manufacturing process. In Phase II, Mainstream will continue the development of the manufacturing process which will then be used to build a full-scale window prototype and test its thermal and optical performance.Approved for Public Release | 17-MDA-9395(24 Oct 17)
