Sharp UHTC leading edges composites for hypersonic applications

2012
Hypersonic vehicles need sharp leading edges to enable vehicle manoeuvrability during atmospheric exit and re-entry. The edges are expected being hit with corrosive plasmas from atmosphere at ablative speeds with temperatures inexcess of 2000°C. Such extreme conditions limit the field of material candidates to ultra-high temperature ceramics (UHTCs ...

Fabrication and plasma wind tunnel testing of UHTC structures

2011
The ultra-high-temperature ceramics (UHTCs) are currently the most studied key enabling technology for thermal protection structures (TPS) like wing leading edges, surface control components to be applied in the next generations of space vehicles flying at hypersonic speed or/and re-entering the Earth's atmosphere.

Sharp composite UHTC leading edges for hypersonic applications

2012
Borides of early transition metals are considered very promising materials for several applications, the most appealing one being currently in the aerospace. The present contribution deals with two UHTC ZrB2-based materials reinforced, respectively, with SiC in form of chopped fibre or fine particulate.

High temperature characterization of an UHTC candidate materials for RLV's

2003
Nose and wing leading edges of the future generations re-entry vehicles will withstand very high temperature in an oxidizing environment. UHTC (Ultra High Temperature Ceramics) materials are very promising candidate materials for such applications. An innovative, proprietary methodology was developed to produce, by plasma spraying deposition, a ceramic
