Hypersonic Weapons Technology Shear Testing of Hypersonic Heatshield Materials at the NASA Hot Gas Test Facility
Abstract
During the past three years, a team consisting of the Naval Air Warfare Center (NAWC), the U,S, Army Aviation and Missile Command (AMCOM) and ITT Aerotherm has been developing thermal protection systems for advanced high-speed missile applications. To date, the development has consisted of evaluating 32 different thermal protection systems (TPS) in representative flight environments. The 32 materials were comprised of proven and unproven aerospace TPS materials ranging from low density ablators to higher density intumescents. Aerothermal tests were performed at the NASA Marshall Hot Gas Facility (HGF). For these tests, materials were subjected to aerothermal heating conditions representative of high altitude and high velocity flight conditions. Two separate test series were conducted with the latter consisting of the best performing 16 of the 33 materials. Since all materials were tested at the same nominal thickness, the top performing material selection was based on a derived performance parameter that equally accounted for weight and volume thereby allowing for a direct comparison between the higher and lower density materials.
