    Abstract: A method of communicating flow through a gas turbine engine having multiple flow paths according to an exemplary embodiment of the present disclosure includes moving core flow along a core flow path from a compressor section to an exhaust section, selectively communicating a first amount of bypass flow from a bypass flow path defined by a bypass duct to the exhaust section or a second amount of bypass flow from the bypass flow path to the exhaust section, the first amount different than the second amount.

    Abstract: A turbine component comprises a platform and an airfoil extending radially away from the platform and extending from a leading edge to a trailing edge. A leading edge portion defines the leading edge of the airfoil and a trailing edge portion including the trailing edge. One of the leading and trailing edge portions also includes the platform. The leading edge portion is formed of a first material distinct from a second material forming the trailing edge portion. The first material has an operating temperature capability at least 100° F. higher than that of the second material. A gas turbine engine is also disclosed.

    Abstract: An air seal includes a sealing gland configured to retain a ferro-fluid and one or more seals. A portion of the one or more seals is configured to extend into the sealing gland. A gas turbine engine, includes the air seal. A method of sealing low pressure air from high pressure air, includes the steps of providing a sealing gland configured to retain a ferro-fluid, distributing the ferro-fluid into the sealing gland, providing one or more seals, wherein a portion of the one or more seals is configured to extend into the sealing gland, and removing the ferro-fluid from the sealing gland.
