[i]The heat shield is fabricated of a special stainless steel honeycomb sandwich manufactured by the Aeronca Co., Middletown, Ohio, and serves as the outer structure of the vehicle. The shield is assembled from 40 individual panels produced by means of a special electric-blanket brazing process. The brazing material used to join the steel skins to the honeycomb is a silver-copper-lithium alloy in a nickel matrix. Each panel is subjected to X-ray inspection after brazing to assure quality.[/i]
[i]Blanket Brazing simply uses a resistance-heated blanket to transfer heat to the brazement by a combination of radiation and conduction. The process is good for contoured parts.[/i]
