  • Vehicle having a nanocomposite optical ceramic dome
    Patent number: 9012823
    Abstract: A vehicle, such as a missile, is disclosed. The vehicle includes an optically transparent dome, a vehicle body, and a brazed joint directly coupling the dome to the vehicle body. The dome is formed of a Nanocomposite Optical Ceramic (NCOC) material comprising two or more different types of nanograins dispersed in one another. Each nanograin type has a coefficient of thermal expansion (CTE), and an aggregate CTE of the NCOC material is based on the CTE of each nanograin type.
    Type: Grant
