Heat and oxidization resistant titanium alloys applications

Objective

According to aircraft market statistics, there is an increasing demand for new helicopters and NC, because European and American citizens are more and more sensitive towards environmental problems. Due to further hardening of environmental standards, A/C and Helicopter manufacturers will have to reduce the noise, CO_2 and Nox levels. Concerning the noise reduction, engine manufacturers have demonstrated high exhaust noise reduction by developing mixers and/or noise exhaust nozzles. But these studies reveal that the weight of these components will be a real challenge, related to the use of conventional technical approaches:
(1) loss of one paying passenger over six for a twin engine helicopter;
(2) cost increase of the noise damping exhausts due to additional devices compared to simple untreated exhaust nozzles;
(3) thrust to weight ratio degradation inducing increased CO_2 emissions. Therefore, Research Centers and Industrials gathered in HORTIA programmed, creating a complementary consortium, to scan all the aspects of the final applications, from the identification of the available materials and associated properties to the performance validation including not only technical criteria but also costs, productibility and maintainability.
