Description
Summary:Engineers have continuously sought to increase fuel efficiency in gas turbines, more than halving fuel consumption over the last 3-4 decades. This was achieved mainly by increasing firing temperatures. Apart from new alloys and cooling methods, thermal barrier coatings (TBC) have played a major role in this development. These coatings were first used on jet engines in the 1970's and are now a common feature on power generation turbines. TBCs allow components to survive higher temperatures and have acceptable service times. TBC technology will continue to play a dominant role in future energy solutions. TBCs are refractory coatings, usually based on yttria stabilized zirconia, that are used to provide thermal insulation and indirectly provide oxidation protection on turbine blades, vanes and combustion chamber liners in gas turbines used in power generation and aviation. This paper has demonstrated for the first time the feasibility of implementing an entire sensor coating system on an operating engine and successfully detecting highly precise measurements.
