The blade device has a shroud, an airfoil extending from the shroud along the radial direction, the shroud has at a circumferential end a wedge face having a recess extending with a component along the axial direction, and a damping wire arranged within the recess such that the damping wire is adapted for contacting the shroud and a further wedge face of a further shroud of a further blade device arranged adjacent to the shroud along the circumferential direction. The recess includes an inclining side surface which has a normal, non-parallel with the radial direction, the further wedge face has a plane surface onto which the damping wire is abuttable. A method of manufacturing a blade system includes arranging the further shroud adjacent to the shroud and arranging a damping wire within the recess.

    摘要: A turbine rotor has a row of turbine blades associated with a circumferential groove in a disk, each turbine blade having foot received in the groove, a blade profile above the foot, and a shroud plate above the profile. Each blade foot and each shroud plate have end surfaces and side surfaces which form a rhomboid, the end surfaces of each shroud plate tapering toward each other along respective radii and abutting the end surfaces of adjacent shroud plates to form a closed ring. The blade profiles are torsionally stressed by applying a force to each plate in a direction parallel to the axis of the disk, thereby twisting the cover plates through an angle alpha so that the side surfaces of adjacent cover plates are circumferentially aligned in a plane perpendicular to the longitudinal axis. This force is maintained by clamping devices applied to the combs of adjacent blades.

    摘要: A steam turbine that passes more turbine driving steam by off-setting the turbine moving blade throat•pitch ratio before operation and, when a blade untwist is generated during operation, causing more turbine driving steam to flow by maintaining an appropriate value, and, at the same time causing the turbine moving blade throat•pitch ratio to swell by giving the blade untwisting angle to the blade cross-sections in regions where the aerodynamic loss is small. The steam turbine is one in which the throat•pitch ratio (S/T) distribution of a turbine moving blade is offset by forming a curve providing at least one minimal value and maximal value by giving blade twist angle to the blade cross-sections in the blade height direction from blade root to blade tip and, at the same time, the distribution of throat•pitch ratio (S/T) taking into consideration blade untwist generated during operation.

    摘要: A compressor blade vibration reduction mechanism for a high-speed radial impeller for minimizing fatigue failures from various excitation sources. The vibration reduction mechanism includes a plurality of loose-fitting lashing pins coupling each impeller blade to an adjacent impeller blade. Each lashing pin extends through a first aperture in a blade located adjacent to the blade tip and through a second aperture of an adjacent blade. The second aperture of each blade is located a greater distance from the leading edge of the blade than the first aperture. The second aperture is located in an area of the blade having lower vibration during operation than the blade location where the first aperture is located.

    摘要: A rotor includes a disc having a plurality of blades extending therefrom. The blades include tip shrouds, each having first and second axial ends, and first and second circumferential faces. The first and second faces of adjacent tip shrouds are spaced from each other to define gaps therebetween. The first and second ends each include U-shaped slots, each having an arcuate damper wire disposed therein. The slots are aligned generally parallel to an axial centerline axis of the rotor for allowing ease of manufacture and assembly while providing effective frictional damping by the damper wires urged by centrifugal force against the slots.
