Ultra High Temperature Ceramics For Hypersonic Vehicle Applications

Ultra high temperature ceramics uhtcs are a class of refractory ceramics that offer excellent stability at temperatures exceeding 2000 c being investigated as possible thermal protection system tps materials coatings for materials subjected to high temperatures and bulk materials for heating elements.

Ultra high temperature ceramics for hypersonic vehicle applications. For more than a decade the materials and structures department dmas of onera has been actively involved in several programmes to develop such materials for different applications hypersonic flights propulsion systems. Ultra high temperature ceramics uhtcs are materials of interest for use in extreme environments that are beyond the capabilities of other materials. Current shuttle rcc leading edge materials. Ultra high temperature ceramics uhtcs are good candidates to fulfill these requirements.

Ultra high temperature ceramics are desirable for applications in the hypersonic vehicle rockets re entry spacecraft and defence sectors but few materials can currently satisfy the associated high temperature ablation requirements. Ultra high temperature ceramics are good candidates to fulfil the harsh requirements of hypersonic applications. Ultra high temperature ceramic matrix composites uhtcmcs are a new subfield within the wider grouping of cmcs that offer applications in rocket and hypersonic vehicle components particularly. Broadly speaking uhtcs are borides carbides nitrides and oxides of early.

Ultra high temperature ceramics are good candidates to fulfil the harsh requirements of hypersonic applications. Some proposed applications for uhtcs include scramjet engine components leading edges and thermal protection systems for hypersonic vehicles plasma facing materials in nuclear fusion reactors solar power concentrators fuel forms in nuclear. 3 sand2006 2925 unlimited release printed june 2006 ultra high temperature ceramics for hypersonic vehicle applications ronald loehman1 erica corral1 hans peter dumm1 paul kotula2 and raj tandon3 1ceramic processing and inorganic materials department 2materials characterization department 3materials reliability department sandia national laboratories. Hypersonic flights re entry vehicles and propulsion applications all require new materials that can perform in oxidizing or corrosive atmospheres at temperatures in excess of 2000 c and sometimes over the course of a long working life.

Ultra high temperature ceramics uhtcs are a class of materials that can be used in environments that exhibit extremes in temperature chemical reactivity erosive attack etc. Temperature requirements on the materials. In our laboratories monolithic and composite materials. For more than a decade the materials and structures department dmas of onera has.
