摘要： A rotor blade having a rotor blade trailing edge which extends between a rotor blade root and a rotor blade tip over a rotor blade length, and having a profile depth which is established between the rotor blade trailing edge and a rotor blade leading edge. For the purpose of improving efficiency, at least one profile element having a continuous profile section, for the purpose of changing the profile depth of the rotor blade, is able to be attached at or in the region of the rotor blade trailing edge, wherein the extension of the profile section beyond the rotor blade trailing edge is determined in a manner dependent on a standardized load-dependent dimensioning of the profile depth of the rotor blade and a load level which is established at an erection location of the wind turbine.

摘要： A seal apparatus for a casing of a turbomachine. The seal apparatus may include an annular body having first and second annular body portions and an appendage. The second annular body portion may extend axially from the first annular body portion and may have an outer annular surface radially offset from an outer annular surface of the first annular body portion. The appendage may extend axially from the first annular body portion and may have an outer annular surface and an inner annular surface. The inner annular surface of the appendage and the outer annular surface of the second annular body portion may define an annular cavity therebetween, and at least a portion of the appendage may be configured to be displaced radially outward in order to maintain contact with first and second inner cylindrical surfaces of the casing during radial expansion of the casing.

摘要： A method for manufacturing a rotor blade panel of a wind turbine includes placing a mold of the rotor blade panel relative to a computer numeric control (CNC) device. The method also includes forming one or more fiber-reinforced outer skins in the mold. The method also includes printing and depositing, via the CNC device, printing and depositing, via the CNC device, a plurality of rib members that intersect to form at least one three-dimensional (3-D) reinforcement grid structure onto an inner surface of the one or more fiber-reinforced outer skins before the one or more fiber-reinforced outer skins have cooled from forming. Further, the grid structure bonds to the fiber-reinforced outer skin(s) as the structure is deposited. In addition, the plurality of rib members include, at least, a first rib member extending in a first direction and a second rib member extending in a different, second direction. Moreover, the first rib member has a varying height along a length thereof.

摘要： A surgical apparatus includes a rotatable shaft and a turbine assembly. The rotatable shaft includes a cutter located thereon. The cutter is configured to cut an object when the shaft is rotating about a rotational axis. The turbine assembly includes a turbine and a turbine housing. The turbine housing is configured to receive a fluid that enters the housing parallel to the rotational axis, and to steer the fluid to impinge on the turbine in a direction that is not parallel to the rotational axis. The turbine is configured to rotate the shaft so as to cut the object by the cutter.

摘要： A radial turbine impeller includes a turbine wheel module including a first surface and a second surface being mutually opposite in the axial direction of the radial turbine impeller. The radial turbine impeller includes blade modules attached to the turbine wheel module. Each blade module is a single piece of material and includes a body portion and blades connected to the body portion and protruding in the axial direction from the body portion. At least the first surface of the turbine wheel module is provided with one or more annular grooves opening in the axial direction and containing the body portions of the blade modules so that, in each of the grooves, the blade modules are successively in the circumferential direction. The radial turbine impeller further includes a securing system for keeping the body portions of the blade modules in the one or more grooves.

摘要： A compressor housing defines an inlet bore having a first inlet collar disposed therein. The inlet collar is connected to the housing with a first plurality of radially extending posts. The first plurality of posts is removed to detach the inlet collar from the housing, and the inlet collar is removed from the housing. The same or another inlet collar is concentrically located within a liner. The liner can be located at a radial distance around at least a portion of the inlet collar. The inlet collar is connected to the liner by radially inserting a second plurality of posts through the liner and into the inlet collar. An assembly of the liner containing the inlet collar is inserted into the inlet bore of the housing such that the inlet collar forms the inducer bore of the compressor housing.
