摘要： A reduction in excitation amplitudes affecting turbine blade durability in a turbine nozzle assembly having a plurality of vanes and turbine blades, includes: identifying a turbine blade design of the turbine nozzle assembly; performing a modal model analysis of at least one of the turbine blades in the turbine blade design; reducing aerodynamic impact by ensuring that each of the turbine blades is free of aero-excitation from an upstream flow at the vanes in an operating speed range; identifying blade natural frequencies with respect to the nozzle vanes; and modifying a trailing edge of at least one of the vanes to reduce the excitation amplitudes.

摘要： The present disclosure is directed to a suspension system for a wind turbine rotor blade and methods for suspending said rotor blade from a hub thereof. The method includes positioning the rotor blade in a substantially six o'clock position. Another step includes removing at least one root attachment assembly from an adjacent rotor blade and providing at least one passageway from an exterior surface of the adjacent rotor blade to the root attachment assembly. Still another step includes inserting a cable through the passageway such that the cable engages an interior surface of the adjacent rotor blade and extends from within the adjacent rotor blade to the lowered rotor blade. The method further includes securing the cable to the rotor blade at an attachment location. Next, the method includes lowering the rotor blade a vertical distance from the hub until the blade is supported by the cable.

摘要： A propulsion system for a tiltrotor aircraft includes an engine supported by the airframe and a fixed gearbox operably coupled to the engine. Inboard and outboard pedestals are supported by the airframe and positioned above the wing. A pylon assembly is rotatably coupled between the inboard and outboard pedestals. The pylon assembly includes a spindle gearbox having an input gear, a mast operably coupled to the input gear and a proprotor assembly operable to rotate with the mast. The spindle gearbox is rotatable about a conversion axis to selectively operate the tiltrotor aircraft between helicopter and airplane modes. A common shaft, rotatable about the conversion axis, is configured to transfer torque from an output gear of the fixed gearbox to the input gear of the spindle gearbox. Each of the inboard and outboard pedestals includes a pillow block housing such as a full or a split pillow block housing.

摘要： A system for enabling servicing of a rotor of a wind turbine is provided. A rotor servicing fixture attaches to a first and second rotor blade, and contacts a wind turbine tower. A clamp assembly is connected to the rotor servicing fixture, and clamps onto a third rotor blade. The clamp assembly lowers the third rotor blade from a hub and raises it back to the hub. A lifting assembly is connected to the rotor servicing fixture and the clamp assembly, and is configured for raising and lowering the third rotor blade via the clamp assembly. A slide assembly is connected to the rotor servicing fixture, and is configured to support the rotor part and to slidably move the rotor part away from or towards the wind turbine. The system enables the rotor part to be removed or replaced without requiring the rotor to be removed from the wind turbine.

摘要： A gas turbine includes an exhaust cylinder comprising an inner circumferential slot, a diffuser shell disposed at least substantially concentrically within the exhaust cylinder and one or more baffle plates extending between the exhaust cylinder and the diffuser shell, a proximal end of each of the one or more baffle plates being fixed to the diffuser shell by one or more holding rings and a distal end of each of the one or more baffle plates being slidingly received within the inner circumferential slot of the exhaust cylinder. The one or more holding rings are secured to the diffuser shell, at one or more holding segments disposed along an inner diameter of the diffuser shell, via a plurality of radially inserted fastening members.
