The throat approach was fabricated from vacuum-bag-cured V-44 elastomeric insulation; the entrance cap from a Kraft paper composite; the throat inlet from carbon-phenolic; the throat from carbon-polyphenylene; the throat extension from silica-epoxy novolac and the exit extension from asbestos-epoxy novolac. 收起
