Abstract
A gas turbine engine comprises a compressor, a combustion system and a turbine, the compressor and the turbine being interconnected by a shaft. The combustion system has an initial diffusing section and duct means are provided to convey cooling air from at least part way down the diffusing section, to the turbine. At least one aperture is provided in the duct means and adapted to allow part of the cooling air to flow forwardly of the shaft on its outer surface to cool it.
