This contribution collects results gained in the LIGHT-TPS project, with focus on two main research pillars: A. New heat resistant dispersion-strengthened by oxides alloys based on NiCr and Nb with densities down to 7.450 and 5.558 g/cm3, respectively, have been developed. Relevant thermo-mechanical properties have been characterized within the temperature range of 20 - 1100 °?. TPS mock-ups have been manufactured on the basis of developed NiCr materials. A 1st mock-up in size of 310 x 150 mm was tested under complex mechanical loading conditions imitating the expected operational loads. A 2nd mock-up in size of 165 x 165 mm was aimed to determine the thermo-mechanical strength of TPS structure. The developed TPS has been qualified in TRL4. B. New UHTC composites in form of either bulks or coatings for service temperatures >1600°C have been developed. Accelerated oxidation tests have shown the potential of these UHTC coatings for the oxidation protection of non-oxide CMC substrates.
