摘要： A gas turbine engine includes a compressor section, a combustion section communicating with and disposed downstream of the compressor section relative to a direction of airflow, and a gas turbine section communicating with and disposed downstream of the combustion section relative to a direction of airflow. One of the sections has a wall defining an opening to access an airflow through the sections. A bleed diffuser assembly is disposed over the opening, and includes a housing including inlet and outlet ends. A diffuser having inlet and outlet ends is movably disposed within the housing. An actuator is coupled to the diffuser for moving the diffuser generally toward the inlet end of the housing and into an operative position when the actuator is energized. A biasing member is provided for urging the diffuser generally toward the outlet end of the housing and into a retracted position when the actuator is de-energized.

摘要： A hybrid airfoil for a gas turbine engine is provided that includes a body and a panel. The body has a first side and a second side orientated opposite the first side. The first and second sides extend between a tip, a base, a leading edge and a trailing edge. The body includes a plurality of cavities disposed in the first side of the body, which cavities extend inwardly toward the second side. The cavities collectively form an opening. At least one rib is disposed between the cavities. A shelf is disposed around the opening. The panel is attached to the shelf first mounting surface and to the rib, and is sized to enclose the opening. The panel is a load bearing structure operable to transfer loads to the body and receive loads from the body.

摘要： A turbofan engine includes a fan driven by a low pressure turbine through a gear reduction. The gear reduction has a gear ratio of greater than or equal to about 2.4. The low pressure turbine has an expansion ratio greater than or equal to about 5. The fan has a bypass ratio greater than or equal to about 8. In other features, a turbofan engine includes a variable geometry fan exit guide vane (FEGV) system having a multiple of circumferentially spaced radially extending fan exit guide vanes. Rotation of the fan exit guide vanes between a nominal position and a rotated position selectively changes a fan bypass flow path to permit efficient operation at various flight conditions.
