Dirt separator for gas turbine air supply

摘要

A gas turbine engine (120) is provided with a radially outer cooling air flow (26). A dirt separator (130) is placed in the path of the radially outer cooling air flow (26), and includes a radially outer leg (134) that defines a space (133) to capture dirt or other impurities. A radially inner leg (135) of the dirt separator (130) includes open air flow passages (136) to allow air to flow through the inner leg (135) and downstream to cool various components within the gas turbine engine (120).
