Development of an Advanced High-Temperature Fastener System for Advanced Aerospace Vehicle Application

摘要

This report documents the results of a program to develop a light-weight high temperature reusable fastening system for aerospace vehicle thermal protection system applications. This feasibility program resulted in several fastener innovations which will meet the specific needs of the heat shield application. The results indicated that a lightweight, reusable, high temperature fastening system can be developed for aerospace vehicle application.nIn the course of this program, a survey was conducted in which all available aerospace and commercial type fastener designs were reviewed and considered as candidates in the program. It was apparent after this review that new designs with adoption of some present fastening technology could satisfy the requirements of the heat shield application.
