Materials Development for Hypersonic Flight Vehicles

The DARPA/Air Force Falcon program is planning to flight test several hypersonic technology vehicles (HTV) in the next several years. A Materials Integrated Product Team (MIPT) was formed to lead the development of key thermal protection system (TPS) and hot structures technologies. The technologies being addressed by the MIPT are in the following areas: 1) less than 3000°F leading edges, 2) greater than 3000°F refractory composite materials, 3) high temperature multi-layer insulation, 4) acreage TPS, and 5) hightemperature seals. Technologies being developed in each of these areas are discussed in this paper.
