摘要： A dirt separator for a gas turbine air supply is provided to prevent a cooling channel from being clogged by dirt, by removing the large amount of dirt found in a radially outer air flow before air reaches a cooling chamber. A gas turbine engine(120) comprises a housing(140) covering a stationary vane(22) and a rotating rotor; a turbine section including the stationary vane and the rotating rotor, wherein at least one of the stationary vane and the rotating rotor is provided with a radially outer cooling air flow from the position adjacent to a radially outer position in the housing; and a dirt separator(130) arranged in a flow path(26) of the radially outer cooling air flow. The dirt separator operates to remove impurities from the radially outer cooling air flow, and air moving downstream of the dirt separator and at least one of the stationary vane and the rotating rotor carries less impurities.
