An earlier report outlined research in progress on the reheat gas turbine under the 'Moonlight Project.'[1] This report deals with the various problems involved in the structural design of the pilot plant 'AGTJ-100A' that is presently under research and development. The AGTJ-100A is basically a heavy-duty gas turbined designed to develop high efficiency in combined cycle operation. Regarding thermal efficiency, in particular, the reheat intercooling cycle is adopted to endow the gas turbine with high efficiency even under partial load conditions, as well as at rated output. With the result that a total pressure ratio of 55 and high-pressure turbine inlet temperature of 1,300℃ are attained. Besides to this, low-pressure turbine inlet temperature of 1,200℃ also requires substantial improvement over normal design practice associated with conventional industrial gas turbines, but for this very reason, various technical problems not encountered before have cropped up-as, for example in connection with structural design works.
