Abstract:

The development of alumina radome attachments was divided into 2 phases. Phase I was devoted to chemical bonding of both the active metal seal type and the metallized ceramic type. In preliminary tests, the active metal technique, whereby the alumina is coated with titanium hydride and placed in contact with a braze foil which in turn is in contact with the refractory metal, appeared to be superior. Excellent, but lower, use temperature bonds were formed initially. Phase II consisted of mechanical attachment engineering studies. A polariscope technique was employed to analyze stress distributions of various attachment configurations. An advanced investigation of simulated elevated temperature 2500F attachment conditions, utilizing room temperature substitutes for alumina and refractory metals at 2500F, was initiated. Author
