Dome Attachment with Brazing for Increased Aperture and Strength

摘要

Missile domes made from Sapphire or other ceramic materials must be attached to metallic structures with different Coefficients of Thermal Expansion (CTE's) without blocking aperture or causing optical deformation due to mounting. High speed, high temperature environments are demanding requiring a strong, robust mount while maintaining optical location and figure. Brazing using compliant, CTE matched materials and active braze alloys have been highly successful in solving these problems for missiles. Descriptions of several different design approaches will be discussed and the advantages of each presented.
