Endo-Atmospheric, IR-Seeker Window Technology Development

"Stratonics, Inc. will develop interceptor technology for IR-seeker windows.The aero-thermal and aero-optical properties of an external, wedged seeker windowwill be the starting point of the project, which will also cover other possibleconfigurations. The technology will advance the window component of the StandardMissile BLK IVA dome, the Army Atmospheric Interceptor Technology (AIT) or otherendo-atmosphere interceptor programs. Endo-atmospheric systems must contend withthe aero-themal loads and aero-optic distortions presented by the flow fields overthe IR-seeker aperture, during high Mach number maneuvers. As proposed, theexternal wedge design has the potential to provide a simpler and better solution toseeker performance with enhanced window survivability. This would replace theexisting dome designs, which require complicated cooling systems. The windowtechnology will be general enough to be appropriate for applications where it islocated at the front of the interceptor or along its side. For the THAADconfiguration, the window is located near the forebody, whereas for the StandardMissile BLK IVA, or AERO system, the window is located further along the body, wherethe boundary layer is thicker. This range of conditions will insure that the newtechnology has wide application to missile defense. The innovative window technology has the potential to become next generation technology for ballistic missile defense systems. As su
