In a gas turbine the transition duct is subject to high temperature since it conducts the combustion products to the power turbine. It is normally cooled by air from the compressor. This invention improves the uniformity of cooling by forcing the cooling air to pass over all surfaces of the transition duct. Air flow passages are formed between the ducts and saddle shaped members which direct the flow of air from the compressor over the outer surfaces of the ducts.

In a gas turbine including a compressor for producing an air flow, a plurality of radially arranged combustors for producing hot combustion gases supplied with air from said compressor, a power turbine, transition ducts coupling said hot combustion gases from said combustors to said power turbine; means to equalize the surface temperature of said transition ducts comprising saddle shaped members overlying a substantial portion of the radially outward surfaces of said transition ducts to direct the said air flow from said compressor to said combustors substantially uniformly over said outward surfaces of said transition ducts, a seal wall through which said transition ducts pass, said seal wall separating the compressor output from said combustors and forcing all of said airflow from the compressor to flow through apertures in said wall in its path to said combustors.
