It is known that Melt-Growth Composite (MGC) material maintains its mechanical strength at room temperature up to about 2100 K, which is ideal for the high temperature gas turbine. The purpose of the present study is to develop the innovative cooling structure of the gas turbine combustor liner with MGC material. The structure of the combustion liner applying to the 1973 K class gas turbine combustor was proposed, and its structure was estimated by the combustion test. Experimental result showed that the surface temperature distribution of MGC panel was obtained and MGC panel installed inside the model sector combustor was healthy at the condition of 1973 K for the combustion gas temperature, and the sector combustor needed less cooling air than conventional combustors.
