Abstract: A blade assembly including an outboard blade segment is provided. The outboard blade segment includes an outboard blade shell, first and second outboard bulkheads situated within the outboard blade shell, and an outer box supported by and aligned by the outboard bulkheads. The blade assembly also includes an inboard blade segment including an inboard blade shell, first and second inboard bulkheads situated within the inboard blade shell, and an inner box supported by and aligned by the inboard bulkheads. Further, the inner and the outer boxes are tapered to facilitate insertion of the inner box into the outer box and coupling of the inner and outer boxes.

Abstract: An application and infusion system for applying a resin to one or more fiber tows and for infusing the fiber tows with the resin, wherein each of the fiber tows is moving at a respective fiber speed. The application and infusion system includes a deposition and infusion system comprising one or more nozzles configured to deposit the resin on a respective one of the fiber tows. The system further includes a controller configured to control a flow rate of the resin through each of the nozzles relative to the fiber speed of the respective ones of the fiber tows. Other aspects of the application and infusion system are also provided.

Abstract: A fan containment casing includes a core comprising a number of tows. The core has a central region and two end regions. The tows are grouped into a number of bands and form a number of filament-wound radially disposed layers. The bands of tows are interleaved as a number of direct bands and indirect bands along at least a portion of one or more of the layers. A method of forming a fan containment casing includes winding a number of tows on a liner to form a number of radially disposed layers, where each of the layers is continuously connected to at least one adjacent one of the layers across one of the end regions via at least one of the tows.

Abstract: A steam turbine system for use in conjunction with hybrid last stage(s) LP buckets. The system is adapted to cool the bucket tip region during low VAN windage conditions whereby the beneficial design and efficiency outcomes of the use of hybrid blades can be realized.

Abstract: In accordance with certain embodiments, a wind turbine blade includes an outer skin and an internal support structure. The skin has a closed airfoil shape and includes an outer surface, an inner surface, and opposite sides along a length of the blade. The internal support structure is disposed within the closed airfoil shape. The internal support structure includes at least one shear load bearing member disposed across the opposite sides and oriented lengthwise along the length of the blade. The internal support structure further includes a plurality of bending load bearing members disposed along the inner surface in a lengthwise direction along the length of the blade. The internal support structure is configured to position a shear center and a center of aerodynamic pressure loading of the blade at different locations relative to one another.

Abstract: A system for controlling blade tip clearance in a turbine. The system includes a stator including a shroud having a plurality of shroud segments and a rotor including a blade rotatable within the shroud. An actuator assembly is positioned radially around the shroud and includes a plurality of actuators. A sensor senses a turbine parameter and generates a sensor signal representative of the turbine parameter. A modeling module generates a tip clearance prediction in response to turbine cycle parameters. A controller receives the sensor signal and the tip clearance prediction and generates at least one command signal. The actuators include at least one actuator receiving the command signal and adjusts a position of at least one of the shroud segments in response to the command signal.
