Abstract: The present disclosure concerns removal of entrained contaminant particles in a coolant airflow for a gas turbine engine. Example embodiments include a coolant airflow assembly for a gas turbine engine, comprising: a coolant feed passage connected between a supply of coolant air and an inlet of a component to be cooled, the coolant feed passage defining a coolant airflow path and comprising first and second opposing internal faces (305, 306), the inlet of the component connected to the coolant airflow path through one of the first and second internal faces (305, 306) of the coolant feed passage; and a particulate filter for removing entrained particles from the coolant airflow path, comprising: a first filter panel extending from the first face into the coolant airflow path upstream of the inlet of the component; and a second filter panel extending from the second face into the coolant airflow path upstream of the first filter panel.

Abstract: A vane assembly includes an aerofoil having a leading edge, a trailing edge, and a pressure surface and a suction surface defined between the leading edge and the trailing edge. The aerofoil includes a blade member forming the trailing edge, at least a portion of the pressure surface and at least a portion of the suction surface. The blade member is formed of a first material. The aerofoil further includes a spar at least partly enclosed by the blade member and forming at least a portion of the leading edge. The spar further forms at least one cooling channel and supports at least a portion of an interior surface of the blade member. The spar is formed of a second material different from the first material. The second material has a greater impact resistance than the first material.
