Ceramic composite lused in combustor and nozzle components. The contract to manufacture the 500 000 pencil sized elements was given to the coors porcelain company. Smart is working with ceramic composite materials engineer john drennan director of uq s centre for microscopy and microanalysis. Ceramic fuel elements would have to be used.

These balls are encased within steel races. The proposed use for nuclear powered ramjets would be to power a cruise missile called slam for supersonic low altitude missile. Each of the heat exchanger panels comprises a plurality of structural panels each having a plurality of. Zrb2 sic based ultra high temperature ceramic uhtc struts were firstly proposed and fabricated with the potential application in the combustor of scramjets for fuel injection and flame holding for their machinability and excellent oxidation ablation resistance in the extreme harsh environment.
