Abstract: The stator vanes and rotor blades of a gas turbine engine are cooled internally by the circulation of a fluid coolant in a closed and sealed system, the heat absorbed from the blades and vanes by the coolant being extracted in a heat exchanger cooled by bleed air from the compressor, and the air thus heated then returning its heat load to the power cycle by being fed into the combustion chamber to take part in the combustion reaction. The engine is designed in such a manner that the turbine rotor with its blades and sealed internal cooling system, and the stator ring with its vanes and sealed internal cooling system, can be disassembled from the engine as units without breaking the sealed cooling system.
