摘要： A high-efficiency compressor section (10) for a gas turbine engine is disclosed. The compressor section includes a vane carrier (12) adapted to hold ring segment assemblies (16) that provide optimized blade tip gaps (28,29) during a variety of operating conditions. The ring segment assemblies include backing elements (30) and tip-facing elements (32) urged into a preferred orientation by biasing elements (40) that maintain contact along engagement surfaces (44,46). The backing and tip-facing elements have thermal properties sufficiently different to allow relative growth that strategically forms an interface gap (42,43) therebetween, resulting in blade tip gaps that are dynamically adjusted operation.

摘要： A method for making a tower for a wind turbine includes: making tower sections, which can be arranged one on top of another; defining two separation lines running in a longitudinal direction for one of the tower sections and providing a longitudinal profile for a separation line, wherein the profile is formed as a single piece with two legs running parallel at a mutual distance; connecting the profile to the tower section, wherein the legs are connected to the tower section on opposing separation line sides; severing the tower section along the separation line into segments mutually separated by a segment boundary, wherein the monolithic profile is severed and each of the legs remains connected to a segment on a different side of the boundary; connecting segments by the legs of the severed profile to a tower section; and, connecting several tower sections to form a tower.

The method can include removing a first selected stator bladerow from the plurality of compressor stages, the first selected stator bladerow having a first inlet swirl angle and including a first plurality of fixed stator vanes. Each stator vane of the first plurality of fixed stator vanes can have a first stator vane angle. The method can also include providing a first improved stator bladerow to replace the first selected stator bladerow. The first improved stator bladerow can have a second plurality of fixed stator vanes, each having a second stator vane angle smaller than the first stator vane angle. The method can also include replacing the first selected stator bladerow with the first improved stator bladerow to produce an increased pressure ratio and flow rate compared to the first selected stator bladerow.

摘要： A hydraulic wave energy converter, for converting wave energy into high-pressure water energy, includes a rectangular upper floating body (1) floating on water surface, a cylindrical housing-shaped lower floating body (2) under water, a first cable (3), a second cable (4), a hanging rod (5), a ball hinged hook (6), a sea floor anchor pile (7), and other mooring facilities. A plurality of water hydraulic cylinders (8) are vertically fixed at two wider sides of the upper floating body (1) and are reliably connected with the lower floating body (2) through piston heads (27), piston rods (28) and piston rod seats (29). The hydraulic wave energy converter can convert the vertical component and the horizontal component of the wave motion into high-pressure water energy for impacting a hydraulic generator set to generate power, and is lower in cost, simple in maintenance and high in wave energy conversion efficiency.
