Gas turbine engine with dirt separator and method of removing impurities from a gas turbine engine

摘要

A gas turbine engine (120) is provided with a dirt separator (140) placed in a path of the radially outer cooling air flow (26), and includes a radially outer leg that defines a space to capture dirt or other impurities. An access port (142) is provided in a turbine engine case in an area adjacent to the dirt separator (140). The access port (142) has two openings (154) at a tangent to the centerline of the gas turbine engine covered by access port covers (156) which can be removed to allow a cleaning tool (150) to have access through the access port (142).
